Multi-Junction Solar Cell To Break Efficiency Barrier Designed By NRL
2013-01-14 11:50:25

U.S. Naval Research Laboratory U.S. Naval Research Laboratory scientists in the Electronics Technology and Science Division, in collaboration with the Imperial College London and MicroLink Devices, Inc., Niles, Ill., have proposed a novel triple-junction solar cell with the potential to break the 50 percent conversion efficiency barrier, which is the current goal in multi-junction photovoltaic development. "This research has produced a novel, realistically achievable, lattice-matched,...

OPV Cells With High Electric Potential For Portable Electronics
2012-10-11 13:04:17

A new breakthrough in solar technology means portable electronic devices such as e-book readers could soon be re-charged on the move in low light levels and partial shading. Scientists from the University of Warwick, in collaboration with spin-out company Molecular Solar, have created an organic solar cell that generates a sufficiently high voltage to recharge a lithium-ion battery directly, without the need to connect multiple individual cells in series. Modules of these high voltage cells...

Black Silicon Used To Make Solar Cells

Solar cells convert three-quarters of the energy contained in the Sun℠s spectrum into electricity — yet the infrared spectrum is entirely lost in standard solar cells. In contrast, black silicon solar cells are specifi cally designed to absorb this part of the Sun℠s spectrum — and researchers have recently succeeded in doubling their overall efficiency. The Sun blazes down from a deep blue sky — and rooftop solar cells convert this solar energy into...

Nanotech Jump For Solar Cells

Solar power cells are limited by the wavelengths of light they can absorb from the sun. Ideally a solar cell would absorb every wavelength, but to date the goal has not been reached. Silicon, today's photovoltaic industry standard, is limited in the wavelength range it can 'see' and absorb. A possible solution has been found in indium gallium nitride. Using this material, scientists can tune the material's response so it collects solar energy from a variety of wavelengths. The more...

The Solar Cell That Also Shines: Luminescent 'LED-type' Design Breaks Efficiency Record
2012-04-19 11:25:59

Research to be presented at the Conference on Lasers and Electro Optics illuminates 50-year mystery To produce the maximum amount of energy, solar cells are designed to absorb as much light from the Sun as possible. Now researchers from the University of California, Berkeley, have suggested — and demonstrated — a counterintuitive concept: solar cells should be designed to be more like LEDs, able to emit light as well as absorb it. The Berkeley team will present its findings at...
