Reverse-bias challenges facing perovskite-silicon tandem solar

Bias of PN Junctions

A small increase in the drift current is experienced due to the small increase in the width of the depletion region, but this is essentially a second-order effect in silicon solar cells. In many thin film solar cells where the depletion region is around half the thickness of the solar cell the change in depletion region width with voltage has a large impact on cell operation.
