Ray-Tracing Analysis of Module-Level Power Generation from Quantum-Cutting Ytterbium-Doped Metal-Halide Perovskites

Using a combination of experimental results and ray-tracing simulations, we analyze the practical performance improvements that ytterbium-doped \mathrm\{CsPb\}(\mathrm\{Cl\}_\{1-x\}\mathrm\{Br\}_\{x\})_\{3\} quantum-cutting downconversion materials can impart on commercially relevant solar photovoltaic technologies. These results demonstrate that optimized ytterbium-doped \mathrm\{CsPb\}(\mathrm\{Cl\}_\{1\}- \{\}_\{x\}\mathrm\{Br\}_\{x\})_\{3\} coatings can provide relative power boosts over 16% when integrated into conventional c-Si modules. We find that the location of the quantum-cutting layer in the module stack and choice of encapsulant are both important considerations for maximizing performance.
