An new type of solar cell has achieved 34.5% conversion of sunlight to energy. It’s a world record and 44% improvement from previous efficiency of 24%, Created by Mark Keevers and Martin Green of UNSW's Australian Centre for Advanced Photovoltaics. Two years earlier, they create...
NREL researchers create a solution-processable “ink” to produce high-efficiency solar cells using low temperature and simple processing. Colloidal nanocrystals (NCs) provide a route toward simplified...
NREL has developed a more precise technology for measuring efficiency of concentrating solar cells, enabling the industry to advance. Solar researchers have long been unable to reduce an...
Ultra-high efficiency solar cells similar to those used in space may now be possible on your rooftop thanks to a new microscale solar concentration technology developed...
Researchers have revealed a new solution-based hot-casting technique that allows growth of highly efficient and reproducible solar cells from large-area perovskite crystals. The researchers fabricated planar...
NREL’s use of potassium fluoride process improves the open-circuit voltage and conversion efficiency. Cu(In,Ga)Se2 (CIGS) solar cells that are fabricated using two-step selenization processes often exhibit low open-circuit...
Combining an Earth-abundant chalcopyrite with a silicon layer could significantly boost conversion efficiency above that of single-junction silicon solar cells. A current technological challenge in photovoltaics (PV)...
Results give insight on a novel, promising class of photoactive materials for solar conversion applications. Organometallic halide perovskites (e.g., CH3NH3PbI3) are a novel class of light absorbing materials...
NREL’s improved time-resolved photoluminescence method measures the minority - carrier lifetime deep within photovoltaic samples to help develop more efficient solar cells. When developing a solar...
NREL’s analytic equation uses open-circuit voltage data to determine how much recombination occurs via different channels in a solar cell. Shockley-Reed-Hall recombination plays an important role...
