On the back side of the panel, a spectral selective reflector was ... “At 12:40, when solar irradiance peaked, v-PV recorded a temperature of 59.6 C, which was still 9 C lower than the h-PV ...

adding that the spectral red-shift indicates a cloud-enhancement of the direct normal irradiance. “We believe the photovoltaic industry requires a quantitative evaluation of the impacts of ...
