Physicists believe they have overcome a significant barrier to the commercialisation of solar cells created with halide perovskites, a class of materials that promise a lower-cost, higher-efficiency replacement for silicon.
A US-Canadian group of scientists has used Lewis base molecules to improve surface passivation in a perovskite solar cell. The team produced a device with a high open-circuit voltage and remarkable stability levels.
US physicists overcame a significant barrier to the commercialization of solar cells made with halide perovskites as a less expensive, more efficient alternative to silicon when harnessing solar energy.
A US-Canadian research group has built an all-perovskite tandem PV device with a record-breaking open-circuit voltage of 2.19 eV, which they achieved by reducing recombination at the electron transport layer.
