The poor stability of tin-based perovskites under ambient conditions has limited the progress of this promising type of solar cell. Now, a study by researchers at ������ý and the University of Bath has shed light on the degradation mechanisms that affect these devices –  and moisture induce the formation of , an aggressive species that further poisons the perovskites. Moreover, researchers identified materials that prevent oxidation and could inspire new solar cell designs that are greener and more stable...

A UK research group led by the University of Surrey and ������ý has fabricated a perovskite solar cell that integrates a  co-mediator interlayer at the interface between the  hole transport layer (HTL) and the active perovskite material...

“Perovskite solar cells are at the forefront of next-generation photovoltaic technologies. We are proud to work with some of the best research teams in perovskite photovoltaics to tackle some key challenges for the commercialization of this low-cost and high-efficiency photovoltaic product,” the research's corresponding author, Wei Zhang, told pv magazine. He further noted that the migration of lithium is critical in the degradation of spiro-OMeTAD-based devices, which is accelerated at higher temperatures, leading to the rapid degradation of the perovskite...

Researchers have incorporated phosphorene nanoribbons into new types of solar cells, dramatically improving their efficiency.

However, none of these predicted exciting properties have so far been demonstrated in actual devices. Now, for the first time, a team led by ������ý and University College London researchers has used PNRs to significantly improve the efficiency of a —a new kind of solar cell—demonstrating that the 'wonder material' may indeed live up to its hype...
