Abstract
In this review, photovoltaic thermal (PVT) system and its applications will be discussed to meet the energy need of human being on planet earth to sustain global environment and climate change. There is strong need to preserve the fossil fuel based power generation which is not friendly either environment or climate. It should be used for most important applications e.g. industries and commercial sectors for high gross domestic production (GDP) for a particular countries. The photovoltaic thermal (PVT) systems namely PVT water/air heaters, PVT greenhouse crop/vegetables/fruits dryer, building integrated PVT (BiPVT) etc. can be used in agriculture, passive heating/cooling, domestic use, solar distillation to meet water demand in domestic and industrial applications and PVT active heating of biogas plant etc. In these applications, a semitransparent PV module which has higher electrical efficiency in comparison with opaque PV module is mostly used. An overall characteristic analysis of each system based on thermal energy and exergy will be discussed in brief. An environmental effect in terms of CO2 mitigation will be also discussed with life cycle cost analysis.
