Sažetak
Nowadays, the majority of market available photovoltaic (PV) technologies are siliceous based PV technologies with a current market share of about 94% and 70% of which are produced in a multi-crystalline variant (Si- poly). Besides a relatively high investment cost and modest overall efficiency, one of the main issues related to siliceous based PV technologies lies in the degradation of PV panel efficiency caused by the elevated PV panel operating temperatures during operation. Depending from the type of specific Si-based PV technology, the degradation rate ranges from 0.25 %/°C up to 0.6%/°C, and the highest one is for Si-poly PV technologies which are used most often. Therefore, in the past two decades, different cooling techniques have been developed for SI- based PVs in order to check the increase in PV panel performance regarding photovoltaic energy conversion, i.e. to achieve an increase in delivered electricity from the PV systems. Based on existing research findings, different active and passive cooling strategies for PVs are briefly elaborated and discussed from a performance point of view as well as taking their general economic and environmental aspects into account.
