Abstract
The efficiency of a c-Si cell drops with increasing cell temperature. A typical photovoltaic module with a c-Si cell will operate 20-30K above ambient temperature. Spectrally-selective photonic mirrors which reflect sub-bandgap light can reduce waste heat generated by parasitic absorption in the module and reduce module operating temperature. Here, a spectrally selective 4-layer and 12-layer mirror are designed and fabricated on module cover glass. When integrated into modules, these mirrors reduce the operating temperature of the module by 0.16K and 1.5K, respectively when compared to a module with bare outer glass.
