Scientists at the Technische Universität Dresden, in Germany, have found that photon recycling and light scattering effects greatly improve light emission in perovskite solar cells, thereby boosting the upper limit for their efficiency to 31.3%.For metal halide perovskites to challenge well-established silicon-based photovoltaics, the former would need to approach the upper limit of photovoltaic efficiency, aka the Shockley-Queisser (SQ) limit, which is only possible if the solar cell is both a good light absorber and emitter. With the latest perovskite solar cells having achieved near-unity light ...Den vollständigen Artikel lesen ...
