The novel cooling approach is dubbed v-PV and employs two 45-degree inclined mirrors on the two sides of a PV module. In the front size, an aluminum mirror was used, letting incident sunlight reflect on the module, while the thermal radiation from the front side can be directed to the sky. On the back side of the panel, a spectral selective reflector was installed, enabling the thermal radiation to be directed to the sky while preventing the back of a module from heating up by the scattered sunlight.
