#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
and generating electricity. In the design of the Hong kong researcherssolar cell, the perovskite serves as active layer for harvesting the light,
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 i
#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,
whether mounting solar cells onto more durable materials such as spring steel could make kirigami systems even more robust t

The UK government has been criticised for guaranteeing the price that will be paid for any electricity the new Hinkley Point reactor produces.
The Solar Trade Association thinks solar power could provide the same amount of electricity for half the subsidy cost.
The government has maintained all along that it will not provide any public subsidies to the nuclear industry. It would not actually be illegal to do so,
or £89. 50 if EDF develops another new reactor in Sizewell, Suffolk. This simply reflects the fact that EDF's costs will be lower per reactor
if it builds two of them. If the market price of electricity falls below this level, the government has said in effect it will make sure EDF receives the difference between the two prices.
The wholesale price of electricity at the moment is about £45/Mwh. If the wholesale price remains at this level
then EDF will receive an additional £47. 50/Mwh. In practice, this money will not come from taxpayers (that would count as a subsidy),
but from consumers of electricity. The strike price works the other way as well-EDF has to refund the difference
if the price of electricity is above £92. 50/Mwh. For example, if the wholesale price is £110/Mwh,
For example, if the price of electricity falls, or becomes more volatile, the company could lose a lot of money.
For this reason, EDF needs an added incentive to build the reactors. Knowing it will receive a guaranteed price for the electricity generated at Hinkley provides some kind of certainty that the investment will be worthwhile-in other words, profitable.
For its part, the government has been unable to play different energy companies off against each other, as German power giants RWE and E on decided long ago against building new plants in the UK.
Until we know the price of electricity on the open market when Hinkley Point C starts generating power,
If the electricity price is below the strike price, then bills will probably be higher than they would otherwise be.
In other words, how much of your electricity is generated by nuclear power. At the moment, almost 20%of the UK's power is generated by nuclear reactors
but why are we building new nuclear power plants? Precisely because there will be a shortfall in electricity generation as a result of existing nuclear-and coal and gas-power stations shutting down.
The question then is how to make up this shortfall. The government is committed to renewable energy, such as solar and wind power,
paving the way for other power companies to invest in new reactors in the UK, because two new reactors will not be enough

#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,
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.
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.
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

#Stanford Engineers Develop Solar cell Cooling Coating To Boost Efficiency A report published by Stanford details the development of a novel cooling technology that its engineers claim can improve solar panel performance.
that at higher temperatures resultant from prolonged exposure to sunlight, solar cells become increasing inefficient at converting sunlight photons into electricity.
In response to this problem the engineers developed a visibly transparent overlay more technically a silica photonic crystal overlay that increases solar cell efficiency by radiating the heat of cells away from them much like how we naturally radiate heat from our bodies to prevent overheating.
This design means that the overlay can be laid on top of an unaltered solar cell this is important since it infers that the new solution requires no additional tampering with the solar cells themselves to achieve cooling effects and enhanced cell performance.
The critical feature of the silica overlay is found in its micron-scale pattern, which is designed to maximise the radiating of heat, in the form of infrared light, out and away from the cell into space.
thereby preserving the energy that required to produce electricity. But as the researchers noted in a statement,
During testing, an overlay was fitted to a solar absorber a device that provides an analogue to the properties of a solar cell and measures absorption of solar radiation,
but doesn actually produce electricity. Several other absorbers were also set up in control conditions. The photograph above kindly provided by Linxiao Zhu,
The bare solar absorber here has structure similar as solar cell, and is bluish. ne can observe that the structure with verlay (the second from left) has same color as the other samples,
in a typical solar cell that difference would confer a significant improvement in overall cell efficiency.
he experimentally demonstrated temperature reduction of 13°C (23°F) would translate to an absolute solar cell efficiency improvement larger than one percentage point a significant solar cell efficiency improvement.
The Stanford Report additionally noted that such a gain in energy production is predicted for a typical crystalline silicon solar cell with an efficiency of 20%.
we are actively looking into directly demonstrating solar cell efficiency improvement from our cooling strategy, by measuring the generated electricity,
explained Zhu. Clearly this is an important step. The overlay has demonstrated successfully its ability to cool a solar absorber,
when paired with a solar cell that is at the same time generating electricity. But still this must be shown under controlled conditions before we may imagine the technology being applied to the production of solar PV cells.
Investigating radiative cooling has been the primary focus of the researchersaims with the solar panel demonstration merely one,
The scientists also consider their findings to hold great potential for application over a wide range of electronic products which could benefit from passive cooling. esides solar cell,
