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 CsPb(Cl1-xBrx)3 quantum-cutting downconversion materials can impart on commercially relevant solar photovoltaic technologies. These results demonstrate that optimized ytterbium-doped CsPb(Cl1- xBrx)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.
