Molecular Movie Reveals Inner Workings of New Solar Cells (Perovskites)

Silicon solar devices remain the dominant market force in photovoltaics, accounting for around 94% of device production in 2016. Although other cells have failed to surpass silicon’s performance, perovskites offer a promising alternative.

Since their discovery in 2009, efficiencies for the fledgling device have continued to climb, moving from 14% to 20% in under two years. Yet, unlike its silicon counterpart, surprisingly little is known about how the metal–organo–halide structure converts light into electricity.
