A joint research team has successfully identified, for the first time, the specific types of defects responsible for efficiency loss in silicon heterojunction (SHJ) solar cells. Subscribe to our ...

Researchers report on a new defect passivation strategy for improved power conversion efficiency and stability of perovskite solar cells. Polycrystalline formamidinium lead iodide (FAPbI 3), widely ...

Solar energy is a crucial part of our clean energy future, but a new, highly efficient solar material has a hurdle that needs to be addressed. A recent study reveals how a microscopic weak spot can ...

Korean researchers revealed that efficiency losses in heterojunction solar cells arise from two coexisting defect types – dangling bonds and weak silicon-silicon bonds. Their findings explain how ...

A joint research team led by Dr. Hee-Eun Song of the Photovoltaics Research Department at the Korea Institute of Energy Research (President Yi Chang-Keun, hereafter “KIER”) and Prof. Ka-Hyun Kim of ...
