A review of solar hybrid photovoltaic-thermal (PV-T) collectors and systems

In this paper, we provide a comprehensive overview of the state-of-the-art in hybrid PV-T collectors and wider systems within which they can be implemented, assess worldwide energy carbon mitigation potential these systems. We cover both experimental computational studies, identify opportunities for performance enhancement, pathways collector innovation, implications their deployment at solar-generation system level. First, classify review main types collectors, including air-based, liquid-based, dual air–water, heat-pipe, building integrated concentrated collectors. This is followed by presentation enhancement innovation. Here, address design modifications, next-generation PV cell technologies, selective coatings, spectral splitting nanofluids. Beyond this, applications, comprising thorough solar combined heat power (S–CHP), cooling, (S–CCHP), desalination, drying hydrogen production includes specific cost improvements level thermal storage, control demand-side management. Subsequently, set most promising assessed to analyse how technology might fit global decarbonization. It estimated that REmap baseline emission curve reduced more than 16% 2030 if uptake technologies promoted. Finally, turns critical examination key challenges adoption recommendations.
