#Solar cells Could Capture Infrared Rays for More Power Nanocrystals and organic materials convert low energy photons into visible light that a solar cell can capture.
Cadmium selenide nanocrystals with one kind of organic coating left produced violet light, while cadmium selenide nanocrystals with another type of organic coating right produced green.
Solar cell efficiencies could increase by 30 percent or more with new hybrid materials that make use of the infrared portion of the solar spectrum,
Visible light accounts for under half of the solar energy that reaches Earth's surface. Nearly all of the rest comes from infrared radiation.

#Will a Breakthrough Solar technology See the Light of Day? The power unit is a rectangular slab about the size of a movie theater screen.
and an equal number of even smaller solar cells, each the size of the tip of a ballpoint pen.
This contraption is part of one of the most efficient solar power devices ever made. Semprius, a startup based in Durham, North carolina,
claims that the next generation of this power unit will make solar power the cheapest option for utilities installing new power plants.
This year it demonstrated that it could use a version of its technology to make a novel kind of solar cell that,
some believe, could convert half of the energy in sunlight into electricity, about three times better than conventional solar cells.
Semprius must scale up the production of its solar cells significantly. Right now it can make enough solar units to produce six megawatts of power per year,
That raises a disturbing possibilityight a breakthrough technology that could make solar power truly competitive never see the light of day, not because of any lack of technical merit,
In the heyday of the solar technology bubble, the ill-fated startup Solyndra raised about $1 billion from venture capitalists
low-cost solar power possible. The stamp, developed in Rogers lab, allows Semprius to improve upon a type of solar power called concentrated photovoltaics,
which has been around for decades (see ltra-Efficient Solar. The idea is that you can increase the amount of energy any solar cell gathers by putting lenses over the cell to focus light into it.
Existing versions of this technology might use a lens with an area of about 400 square centimeters and focus it on a one-centimeter solar cell, for a concentration ratio of 400.
Semprius stamp makes it possible to make arrays of solar cells that are far smaller and thinner than the ones that had been used in concentrating photovoltaics.
For the concentrating technology to work the solar cells need to be picked up and arranged in an array
so they can be paired with an array of lensesnd that where the rubber stamp comes in.
and transfer thousands of the tiny solar cells at once without breaking them, completely changing the economics of using small solar cells.
Small cells have many advantages; because they require little material, they can be made of expensive types of semiconductors that are far more efficient than silicon.
and real estate to generate the same amount of power as a typical solar cell. These advantages,
and some clever lens designs, allowed Semprius to break a solar power efficiency record in 2012.
and Siemens drawing on its expertise in building solar power plants. But 15 months after Siemens invested in Semprius,
Huge investments in conventional silicon solar power, especially in China had lowered costs of production but also flooded the market with cheap solar panels.
Given the supply of cheap solar panels, it became nearly impossible for companies with alternative technologiesuch as thin film solar
or concentrated photovoltaicso compete. Dozens of promising solar startups failed and the projected market for concentrated photovoltaics shrank,
Semprius solar devices are suited best for use in solar power plants. Having the backing of Siemens would have helped convince utilities to take a chance on novel technology.
conventional silicon solar panels still have room to become significantly cheaper and more efficient. New ways of manufacturing silicon wafers, the most expensive part of a solar cell, could cut wafer costs in half
or more (see raying for an Energy Miracle. New solar cell designs are edging up their efficiencies.
Such advances might eventually make solar power cheaper than fossil fuels, even without Semprius technology. But silicon-based solar power is not yet there,
and that the opportunity for Semprius. The U s. Energy Information Administration estimates that new solar power plants will produce power at just under 15 cents per kilowatt-hourar higher than the 6. 5 cents per kilowatt-hour for natural gas power.
Thus, if Semprius is right that it will soon have technology to make solar panels capable of producing electricity at around 5 cents per kilowatt-hour,
its technology could be attractive to those planning new power plants. o invention is required, just good, solid engineering,
Burroughs says. So Semprius continues its search for a new investor to scale up its technology.

The solar cells use an inexpensive and easily manufactured material known as perovskite, which has been generating excitement in the research community
but consider that most solar cells convert only 16 percent of the energy in sunlight into electricity,
For one thing, it only lasts a few hours before the solar cell performance quickly drops off. Researchers aren sure why perovskite materials degrade quickly

because excess wind and solar power creates a glut of power on the grid. Because power needs to be used as soon as it s generated to keep the grid stable prices are dropped sometimes to zero
When experts talk about future solar cells they usually bring up exotic materials and physical phenomena. In the short term however a much simpler approach stacking different semiconducting materials that collect different frequencies of light could provide nearly as much of an increase in efficiency as any radical new design.
The startup Semprius based in Durham North carolina says it can produce very efficient stacked solar cells quickly
Conventional solar cells convert less than 25 percent of the energy in sunlight into electricity. Semprius has come up with three key innovations:
In its designs Semprius uses tiny individual solar cells each less than a millimeter across. That reduces costs for cooling
but also stacks several different combinations resulting in a solar panel that can capture more energy from sunlight. Semprius has demonstrated cells made of three semiconductor materials stacked on top of a fourth solar cell that would not have been compatible otherwise.
It has made two versions of the device this year one with an efficiency of 43.9 percent
In addition to being fast and precise the approach also makes it possible to reuse the expensive crystalline wafers that multijunction solar cells are grown on.
With economies of scale however such cells could improve the economics of solar power. At a scale of 80 to 100 megawatts a year of manufacturing capacity a cell with 50 percent efficiency would make it possible to reach costs of less than five cents per kilowatt-hour Burroughs says.
#Adaptive Material Could Cut the Cost of Solar in Half A material with optical properties that change to help it capture more incoming sunlight could cut the cost of solar power in half, according to Glint Photonics,
a startup recently funded by the Advanced Research Projects Agency for Energy (ARPA-E). Glint adaptive material greatly reduces the cost of a tracking system used in some types of solar power.
cheaper solar cells. But this is usually done with lenses or mirrors, which must be moved precisely as the sun advances across the sky to ensure that concentrated sunlight remains focused on the cells.
where a small solar cell is mounted to generate electricity. As the day goes on, the beam of light from the lenses moves and the material adapts,
and reducing the need to keep the apparatus pointed directly at the sun. Glint CEO Peter Kozodoy says solar power from its devices could cost four cents per kilowatt-hour,
compared to eight cents per kilowatt-hour for the best conventional solar panels. This month, the company received the first installments of a $2. 2 million grant from ARPA-E. The ARPA-E funding will allow the company to scale up from prototypes just 2. 5 centimeters across to make 30

#Sharp Demonstrates Ultra-Efficient Solar cells The best solar cells convert less than one-third of the energy in sunlight into electricity
If it can be commercialized it would double the amount of power a solar cell can generate offering a way to make solar power far more economical.
when sunlight strikes a solar cell it produces some very high-energy electrons but within a few trillionths of a second those electrons shed most of their energy as waste heat.
The Sharp team found a way to extract these electrons before they give up that energy thereby increasing the voltage output of their prototype solar cell.
In theory solar cells that exploit this technique could reach efficiencies over 60 percent. The approach is one of several that could someday break open the solar industry
High-efficiency solar cells would lower the cost of installation which today is often more expensive than the cells themselves.
and figuring out how to make them with high precision (see Capturing More Light with a Single Solar cell and Nanocharging Solar).
which create a shortcut for high-energy electrons to move out of the solar cell. Another way to achieve ultra-high efficiencies now is by stacking up different kinds of solar cells (see Exotic Highly Efficient Solar cells May Soon Get Cheaper)
but doing so is very expensive. Meanwhile MIT researchers are studying the transient behavior of electrons in organic materials to find inexpensive ways to make ultra-efficient solar cells.
Each of the alternative approaches is at an early stage. James Dimmock the senior researchers who developed the new device at Sharp says he expects that his technique will initially be used to help boost the efficiency of conventional devices not to create new ones s
