Review: Developments of Photovoltaic/thermal (PVT) Collectors

Abstract

The alarming energy concerns have stimulated a transition of energy sources to a more sustainable way. Among all of the green energy sources, solar is the most promising one. Recently, a new application called photovoltaic/thermal panels that harvest both long-wavelength and short-wavelength radiations has been gaining attention. Evidence shows that the combined system is more efficient than the two separate systems. Its wide range of applications can significantly promote the transition to a cleaner energy source. This work provides an introduction to the PV/T panels and examines the improvement possibilities of the PV/T panels. Challenges and suggestions for future researches will be discussed.
