Performance evaluations and applications of photovoltaic-thermal collectors and systems

This paper presents the performance evaluations and applications of the photovoltaic-thermal collectors and systems. The performances of the photovoltaic-thermal air collectors and photovoltaic-thermal water collectors are analyzed and discussed. The applications of the photovoltaic-thermal systems, such as building integrated photovoltaic-thermal systems, concentrating photovoltaic-thermal systems and photovoltaic-thermal heat pump systems are presented. Several factors affecting the performances and characteristics of the photovoltaic-thermal systems are also summarized.
