The paper examines strategies to improve the efficiency of photovoltaic (PV) systems, which are challenged by high operating temperatures that reduce performance. It focuses on enhancing PV systems through the use of gallium arsenide (GaAs) thin films and reviews techniques like spectral beam splitting to boost efficiency, particularly in multi-junction PV receivers and hybrid collectors. The study also explores Photovoltaic-thermal (PVT) systems that combine PV cells with thermal absorbers, highlighting advanced absorber designs, mini/microchannels, and the use of polymers over traditional metals. Additionally, the incorporation of phase change materials (PCM) and nanofluids is discussed for their potential to improve thermal conductivity and storage. By synthesizing experimental and numerical research, the paper emphasizes the importance of these innovations in advancing PVT systems for sustainable energy production.
