Destructive Reverse Bias in Perovskite Tandem Modules
Jun 11, 2020|
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 Al Doping on Surface Passivation of TiOx
Apr 13, 2020|
In this work, we find that the crystallization of ALD TiOx is very sensitive to the film’s thickness, where a small increase in TiOx thickness can trigger a phase change from amorphous TiOx into anatase, which causes a significant increase in J0s. More importantly, we demonstrate that the incorporation of Al ions into the TiOx films inhibits crystallization, which in turn retains excellent passivation for thicker TiOx.
Predicting realistic annual yield for solar modules
Sep 12, 2019|
• Optimizing module design for a maximum annual performance. • Detailed gain and loss analysis from cell under STC to module in real environment. • Understanding the impact of module material on the annual module yield. • Impact of angular light, temperatures, lower irradiances on module performance. • Impact of weather condition (ambient temperature, wind speed) on module performance.
