Korean scientists build semi-transparent perovskite solar cell with record-breaking efficiency of 22.02%

Developed by researchers at the Korea Institute of Energy Research (KIER), the novel cell was conceived for applications in bifacial perovskite-silicon tandem PV devices. The academics claim they were able to overcome an intrinsic dopant-induced internal degradation mechanism which leads to undesired lithium-ion diffusion that would have been detrimental to the cell efficiency. The Korea Institute of Energy Research (KIER) announced that a group of its researchers has developed a semi-transparent perovskite solar cell intended for applications in bifacial perovskite-silicon tandem PV devices. ...
