We demonstrate how perovskite hysteresis can result in permanent reductions in power output in perovskite/silicon tandem modules—including irreversible hotspot-induced damage—from only brief periods of shading.

Impact of perovskite solar cell degradation on the lifetime energy yield and economic viability of perovskite/silicon tandem modules

Hotspots are a major source of failure for photovoltaic modules in the field. The current standard for module testing IEC 61215-2 can leave critical hotspots undetected in half-cut solar cell modules.

A two‐step method to simulate the spatially resolved temperature of a partially shaded cell in a crystalline silicon photovoltaic (PV) module is presented and tested.

The impact of partial shading on cell operating current, voltage, and temperature is simulated, for a half-cell module with series-parallel-series connections and for the conventional full-cell module.
