For energies below the bandgap, the thick base layer of the solar cell plays no role in determining the emissivity but rather the much thinner layers, confirming that the complete structure, layers and texture, needs to be considered and properly modelled.
While there is some scope for increasing solar cell efficiency by enhancing radiative emission, our results show that most PV modules in the field are already good radiative thermal emitters. Conversely, it is likely that the thermal efficiency of PV-T collectors is significantly limited by radiative losses.
The emissivity of an unencapsulated c-Si solar cell is determined to be 75% in the MIR range, and is dominated by free-carrier emission in the highly doped emitter and back surface field layers; both effects are greatly augmented through the enhanced optical outcoupling arising from the front surface texture.
The first full radiative model including UV/VIS/NIR absorption and MIR emission. C-Si solar cells are found to be good radiative thermal emitters. Emissivity of commercial silicon solar cells has been understated in recent Works. Efficiency of PV-T collectors is significantly limited by radiative losses.
Effect of encapsulation on the emissivity In a PV module, c-Si solar cells are encapsulated in ethylene vinyl acetate (EVA) and then covered with around 3 mm of soda-lime-silica low-iron glass , . This serves to protect the solar cells from dust and moisture and provide rigidity.
Using optical modelling, we have identified the origin of radiative emissivity in both encapsulated and unencapsulated solar cells. We find that both encapsulated and unencapsulated c-Si solar cells are good radiative emitters but achieve this through different effects.
