Reverse-bias resilience of monolithic perovskite/silicon tandem solar cells

In commercial, silicon (Si) wafer-based modules, reverse-bias-induced degradation is largely mitigated by introducing bypass diodes anti-parallel to substrings of cells, which prevents the shaded cell to be thrusted into reverse bias. 28 Moreover, cell substrings are often connected in parallel to decrease the dissipated power resulting …
