Advances in liquid based photovoltaic/thermal (PV/T) collectors
Daghigh, R.; Ruslan, M.H.; Sopian, K. - In: Renewable and Sustainable Energy Reviews 15 (2011) 8, pp. 4156-4170
In order to get more power and heat from PV/T system, it is necessary to cool the PV cell and decrease its temperature. This is not an easy task especially in hot and humid climate areas. There is a lack of an effective cooling strategy of PV/T panels. The liquid based photovoltaic thermal...
