Chinese researchers have developed a new solar cell with an n-i-p planar structure and an indium tin oxide (ITO) substrate. It also features a tin(IV) oxide (SnO2) buffer layer, a perovskite layer, a hole transport layer (HTL) and a copper layer. It was able to retain around 92% of its initial efficiency after 1,000 hours.
