A comprehensive review of photovoltaic-thermal (PVT)

Kern and Russell (1978) first proposed the PVT system in the mid-1970s to address the issue of solar efficiency decline with increasing solar cell temperature. Because more than 80% of renewable power energy is converted to heat, that can harm PV cells if not stored in a thermal collector (Diwania et al., 2020).The concept of PVT system is depicted in Fig. 2.
