태양광열 복합시스템의 연구동향 분석

A photovoltaic/thermal(PVT) system is a combination of photovoltaic (PV) and solar thermal collectors which produce both electricity and heat from one integrated component or system. The system removes heat from the PV module that would help to raise the efficiency of the PV system is performance. It is useful to utilize the waste heat for building space heating as this multi-function application of solar energy will improve the viability of the system. Many innovative systems and products have been put forward and their quality evaluated by academics and professionals. Although PV/T collectors are promising, it is evident that further research is required to improve efficiency, reduce costs and resolve several technical design issues related to the collectors. This paper describes research and development trends of Photovoltaic-solar combined system. It classified PVT collectors by air type and water based type, flat plate and concentrating PVT system type. This study provides the recent status of researches on PVT system and describe about the analysis of system performance.
