6 FAQs about [Solar cell base emission]
Is emissivity of commercial silicon solar cells understated?
Emissivity of commercial silicon solar cells has been understated in recent Works. Efficiency of PV-T collectors is significantly limited by radiative losses. The thermal emissivity of crystalline silicon photovoltaic (PV) solar cells plays a role in determining the operating temperature of a solar cell.
Can solar cells increase thermal efficiency by enhancing radiative emission?
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.
