Organic–inorganic
hybrid perovskite materials, as promising candidates for high-efficiency
silicon-based tandem solar cells, have passed reliability testing
at 85 °C for 1,000 h. However, silicon photovoltaic modules experience
elevated temperatures under fault operating conditions. We propose
and simulate tandem modules using two- and four-terminal tandem cells
and show potential detrimental temperatures under realistic shading
conditions. A module using series-connected two-terminal cells reaches
207 °C compared to 137 °C for four-terminal cells from simulation.
The cell temperature can be reduced with interdigitated-back-contact
cells, additional bypass diodes, or silicon half-cell configurations.
