Perovskite potential

Perovskite potentialDriven by their achievements in solar cells, metal halide perovskites are being used in a range of other devicesfrom light-emitting diodes to photodetectors to field-effect transistors -with increasing success.T he Rank Prize, which was established in 1972, is awarded biennially to researchers in the fields of nutrition and optoelectronics.It's an unusual combination of topics, and one that reflects the business interests -in flour milling and film making -of the prize's founder, J. Arthur Rank.This year, the Rank Prize for Optoelectronics has been won by seven researchers for pioneering work on perovskite semiconductor solar cells.They are, in particular,
