Solar cell with transparent passivate contact achieves 23.99% efficiency German scientists have built a solar cell with ultra-thin transparent layers that are claimed to be effective in preventing recombination events. The technology, which has the potential of achieving efficiencies close to 26%, may be easily scaled up for commercial production.Researchers from the Jülich Institute for Energy and Climate Research (IEK-5) in Germany claim to have fabricated a prototype of solar cell based on a transparent passivate contact (TPC) with a power conversion efficiency of 23.99%. The result was confirmed by the CalTeC laboratory of the Institute for Solar Energy Research ... Den vollständigen Artikel lesen ...
