although digital cameras and solar panels have different purposes-one measures light while the other converts light to power-both are constructed from essentially the same components.
The same photodiode is used also in solar panels to convert incident light to electric power. The photodiode in a camera pixel is used in the photoconductive mode
while in a solar cell it is used in the photovoltaic model. Nayar, working with research engineer Daniel Sims BS'14 and consultant Mikhail Fridberg of ADSP Consulting, used off-the-shelf components to fabricate an image sensor with 30x40 pixels.
This research outcome potentially allows for great flexibility in the design and optimization of electronic and optoelectronic devices like solar panels and telecommunication lasers.
That alliance also has led to important advances in the use of quantum dot materials to create highly efficient solar cells and sodium batteries,
#Nanoscientists Improve the Stability of Perovskite Solar cells UCLA researchers have taken a step towards next-generation perovskite solar cells by using a metal oxide andwich.
UCLA professor Yang Yang, member of the California Nanosystems Institute, is renowned a world innovator of solar cell technology
whose team in recent years has developed next-generation solar cells constructed of perovskite, which has remarkable efficiency converting sunlight to electricity.
This is a significant advance toward stabilizing perovskite solar cells. Their new cell construction extends the cell effective life in air by more than 10 times
Postdoctoral scholar Jingbi You and graduate student Lei Meng from the Yang Lab were the lead authors on the paper. here has been much optimism about perovskite solar cell technology,
In less than two years, the Yang team has advanced perovskite solar cell efficiency from less than 1 percent to close to 20 percent. ut its short lifespan was a limiting factor we have been trying to improve on since developing perovskite cells with high efficiency.
Endowed Chair in Engineering at UCLA, said there are several factors that lead to quick deterioration in normally layered perovskite solar cells.
The next step for the Yang team is to make the metal oxide layers more condensed for better efficiency and seal the solar cell for even longer life with no loss of efficiency.

#Graphene and Perovskite Lead to Inexpensive and Highly Efficient Solar cells Perovskite is the new buzzword in photovoltaics.
Now researchers at Hong kong Polytechnic University have combined these two materials to make a semitransparent solar cell capable of power conversion efficiencies around 12 percent, a significant improvement over the roughly 7-percent efficiency of traditional
semitransparent solar cells. The semitransparent design of these solar cells means that they can absorb light from both sides
and could allow them to be used as windows that serve the dual function of letting light into a building
The researchers were able to improve the energy conversion capability of the solar cells by employing a multi-layer chemical vapor deposition process in
They claim that their solar cells cost less than US$. 06/watt, which they reckon is more than a 50 percent reduction in the costs of silicon solar cells.
They believe that the whole process is ripe for scaling up because the mechanical flexibility of the graphene enables the possibility of roll-to-roll processing o

#Japanese Paper Cutting Trick for Moving Solar cells To maximize the amount of electricity that solar cells generate,
solar panels can be tilted to track the position of the sun over the course of a day.
Now materials scientist Max Shtein and his colleagues at the University of Michigan at Ann arbor have developed novel solar cells that integrate tracking into their design.
The scientists cut kirigami designs into a 3-micron-thick flexible crystalline gallium arsenide solar cells mounted on plastic sheets.
A solar cell array of this type can tilt in three dimensions in a highly controllable manner
The researchers found that their new devices could generate roughly as much power as solar cells mounted on conventional trackers.
Shtein and his colleagues suggest that kirigami solar panels could be simple, inexpensive and lightweight, and have widespread rooftop, mobile,

When Bearings Inside Wind turbines Will Fail Engineers from the University of Sheffield have developed a novel technique to predict
when bearings inside wind turbines will fail which could make wind energy cheaper. The method, published in the journal Proceedings of the Royal Society A and developed by Mechanical engineering research student Wenqu Chen,

#How Sunport Delivers Solar energy Without the Panels At of the end of 2014, the amount of electricity from solar power being generated in the US was only 0. 8%of the total energy mix in our electrical grid.
Last year, nearly 645,000 US homes and businesses were using power from the sun. That like saying every person in Nashville,
what you see in the chart above to about 3%of our grid energy mix coming from solar by 2040 (note that the chart above doesn account for rooftop solar power).
with the hope of boosting all renewable energy generation by 2030 by 30%.%Yet, even with these measures, nonrenewables will still dominate our energy mix
but today most people are locked simply out of participating in solar energy, says Paul Droege inventor of the Sunport. he expense of solar panels and required ownership of a roof limit solar growth.
The Sunport smart device plugs into the wall between the electricity grid and your powered devices
serving as a portal to the solar energy on the grid. Sunport is the world first smart grid solar delivery device,
It does this by leveraging the same solar renewable energy certificates (SRECS) market that large corporations use to reduce their carbon footprints.
Solar panels are required still to make this solar energy, but you don need to own them. Sunport platform lets you access expensive solar infrastructure,
plugged into an enabled Sunport consumes solar energy without requiring any additional steps. Sunport simply measures the power from the wall
validated solar energy. In the late 1990s, the government created renewable energy credits (RECS) as a way to separate renewable from nonrenewable energy.
Serving as tradable environmental commodities, RECS represent proof that 1 megawatt-hour (MWH) of electricity was generated by an eligible renewable energy source.
A certifying agency gives each REC a unique identification number to make sure it doesn get double-counted.
but money goes to a solar power producer when you buy an SREC. Today SRECS are used primarily to help fund a portion of new solar projects.
and legitimately claim use of any grid-connected renewable energy. This process matches energy use against a solar energy supply (using SRECS) in strict accordance with
what the US Federal trade commission (FTC) requires to claim use of solar energy. Moreover, for each dollar Rechoice spends to acquire SRECS,
it spends a matching dollar to install new solar on other nonprofits, which get free electricity from those installations.
#First Offshore wind farm In U s. Under Construction In July, American offshore wind developer, Deepwater Wind, installed the first foundation for
what is expected to be the first offshore wind farm in the United states. The project will be located three miles southeast of Block island, Rhode island.
the Block island Wind farm is expected to come online in 2016. Deepwater Wind, the developer, is also planning two larger offshore projects along the Atlantic coast,
The National Renewable energy Laboratory (NREL) estimates that the United states has 4 200 gigawatts (GW) of developable offshore wind potential, compared to its estimate of 11,000 GW of onshore wind potential.
Wind resources are classified on a scale of zero to seven based on their power density, and more than 66%of offshore wind in the United states is in wind power class six or seven.
In addition, offshore wind turbines are built to take advantage of the more consistent wind speeds present over the ocean,
allowing higher utilization rates for offshore generation capacity when compared with similarly sized onshore wind turbines.
However, offshore wind is significantly more expensive to build and maintain than onshore wind. Although there are currently no operating offshore wind projects in the United states
offshore wind turbine technology has grown steadily in Europe, and, to a lesser extent, in Asia. As of 2014, Europe accounted for 90%of the estimated 8. 8 GW of installed global offshore wind turbine capacity.
Offshore wind power development in Europe began in 1991 when the first offshore farm was installed off the coast of Denmark,
although the industry had little growth from that point until the 2000s. In the United states, developers have proposed building nearly 4. 9 GW of offshore wind capacity off the coasts of nine different states,
but some challenges remain even for projects that have advanced through key regulatory and market milestones.
For example Cape Wind, a 486-MW project proposed in 2001, faced significant challenges and litigation that halted its progress.
In 2014, National grid and Eversource Energy terminated the power purchase agreements with Cape Wind because of missed project development deadlines.
This past March, Cape Wind canceled its lease in New Bedford, Massachusetts, for its planned project-staging area.
Other projects such as the Virginia Offshore wind Technology Advancement Project and Fisherman Energy Wind of New jersey have faced development hurdles despite making significant progress in project development.
Compared with Western europe, the current leader in offshore wind energy the United states is estimated to have more abundant and favorable onshore wind resources,
which are located largely in areas with low population density. So far, the high cost of domestic offshore wind projects has made them economically unattractive,
despite the availability of federal tax incentives and state policies to promote use of renewable energy.
In contrast, onshore wind capacity has grown by more than a factor of 25 since 2000. Building and maintaining offshore wind technology is compared expensive with onshore wind projects because of challenges such as transporting equipment and workers to the sites
securing turbines to the seafloor, and operating in fewer periods of fair weather. The harsher offshore environment not only makes it difficult
the Kochi airport in the south Indian state of Kerala switched to solar power and created headlines across the world.
Now, another airport is set to adopt solar power to meet a majority of its power needs.
The Netaji Subhash Chandra Bose airport in Kolkata will have a utility-scale solar power project of 15 to 20 MW capacity.
The Airports Authority of India (AAI) recently announced that major airports in the western state of Rajasthan would also set up solar power projects to meet a part of their power demand.
The Jaipur airport already has a 100 kw rooftop solar power system and is planning to set up a 1. 8 MW ground-based power project.
Other Indian airports have also set up solar power projects to meet a part of the demand, as well as earn additional revenue.
