Single-junction perovskite devices can already convert more than 27% of sunlight into electrical energy, while perovskite-silicon tandem cells have achieved efficiencies of more than 35%. Until now, a layer of so-called \u201cfootball molecules\u201d (C<sub>60<\/sub>) has been used to transport electrons away. However, a significant proportion of the charge carriers are lost at the interface between the C<sub>60<\/sub> layer and the perovskite absorber. Furthermore, C<sub>60<\/sub> materials are relatively expensive and tend to delaminate over time, compromising the cell\u2019s stability.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>A newly developed material for the electron contact improves the efficiency of single perovskite solar cells and perovskite\/silicon tandem solar cells.
