Dark IV Measurements
Since solar cells convert light to electricity it might seem odd to measure the photovoltaic cells in the dark. However, dark IV measurements are invaluable in examining the diode properties. Under illumination, small fluctuations in the light intensity add considerable noise to the system making it difficult to reproduce.
Reverse-bias resilience of monolithic perovskite/silicon tandem solar cells
We experimentally demonstrate that monolithic perovskite/silicon tandem solar cells possess a superior reverse-bias resilience compared with perovskite single-junction solar cells. The majority of the reverse-bias voltage is dropped across the more robust silicon subcell, protecting the perovskite subcell from reverse-bias-induced …

Bias of PN Junctions | PVEducation
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.
