As a result, monolithic perovskite/silicon tandem solar cells, when compared with perovskite single-junction solar cells, show superior reverse-bias resilience in both long-term reverse voltage biasing tests at the single-cell level and partial shading tests at the module level, making them more promising for commercialization.
However, we highlighted that the tandem solar cells' resistance to the reverse bias is not universal but depends on the electrical and optical design of the device. In fact, the protection from silicon is effective if the bottom cell features a breakdown voltage in the range of −40 V along with a high shunt resistance.
Therefore, the largest reverse bias that could be experienced by a shadowed cell will be ≈−38 V (assuming a Voc of 2 V for each cell). Therefore, a reverse bias experiment at −40 V as shown in this work could be a good figure of merit for the development of shadow-resilient tandem solar modules.
Herein, we demonstrate that by employing a monolithic perovskite/silicon tandem structure, the perovskite subcell can be effectively protected by the silicon subcell under reverse bias.
