Effectiveness of cooling strategies for photovoltaic technologies

The majority of market available photovoltaic (PV) technologies are silicon based PV technologies with a current market share more than 95%. Besides a relatively high investment cost and modest overall energy conversion efficiency, one of the main drawbacks related to siliceous based PV technologies is associated with performance degradation caused by the elevated PV panel operating temperatures during their regular operation. Elevated operating temperatures in the long term are also increasing performance degradation rate, which finally reduces the lifetime of the PV panel. Therefore, in the past two decades, different cooling techniques have been developed for SI- based PVs in order to check potential increase in performance. Based on existing research findings, different active and passive cooling strategies for PVs are briefly elaborated and discussed from techno- economic and environmental point of the view.
