Photovoltaic Efficiency: The Temperature Effect

Web1. After the characterization of a solar cell under standard test conditions (STC), the efficiency is 18.6%. What would the efficiency of the solar cell be (in %) if the external quantum efficiency (EQE) were halved and all the other external parameters remained the same? Expert Answer WebOct 31, 2024 · The ideal temperature for panels is 25ºC (77ºF), which is the one used for STC. For crystalline solar panels, the temperature varies the efficiency of PV modules by -0.35 – 0.55%/ºC differing from the 25ºC STC. This means that solar panels at an external temperature of 35ºC (95ºF), would have an efficiency reduced by 3.5 – 5.5% ...
