Analysis and modelling the reverse characteristic of photovoltaic cells
The study of photovoltaic (PV) devices working in reverse bias was significant since high voltages and abnormally high temperatures were found in spatial PV applications [1]. From that, and with the identification of the hot-spot effect, studies were performed to analyse its consequences [2] and to evaluate its influence in series–parallel …

Impact of the Current on Reverse Bias Degradation of Perovskite Solar Cells …
Nonequal current generation in the cells of a photovoltaic module, e.g., due to partial shading, leads to operation in reverse bias. This quickly causes a significant efficiency loss in perovskite solar cells. We report a more quantitative investigation of the reverse bias degradation. Various small reverse biases (negative voltages) were applied for different …

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 …
