The importance of the photovoltaic technologies is important in energy transition and it is followed by significant rise in annually globally installed PV capacities. The majority of market available photovoltaic (PV) technologies are silicon based PV technologies with a current market share over 90%. 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, and which also affects the lifetime of PV panels. In the past two decades, different cooling techniques have been developed for SI- based PVs in order to investigate potential increase in the performance and in general impact of cooling. Based on existing research findings, different active and passive cooling strategies for PVs are briefly elaborated and discussed from techno-economic point of the view, together with provided overview of the existing market available PV technologies. The step further in development of the more advanced and targeted cooling techniques for PVs would be also discussed.
Prof. Dr. Sandro Nižetić is a Full Professor at the Faculty of Electrical Engineering, Mechanical Engineering and Naval Architecture (FESB) at University of Split (Croatia). His research is in the field of thermodynamics, energy, energy efficiency in buildings, smart technologies and renewable energy sources. He has twenty years of the teaching experience and from 2005 he is an ASHRAE member and also ASHRAE student branch advisor at University of Split. He has worked on various projects related to the implementation of energy efficiency measures in public buildings under the auspices of UNDP (United Nations Development Programme). He was also the head of the several national research’s projects. He also served as a Deputy Minister in the Ministry of Construction and Spatial Planning in the Croatian government, and also as Vice Dean of Research at FESB. Prof. Dr. Nižetić has organized and chaired several international conferences (IEES, ICH2P, SpliTech,ICRIC, GCGW-21,PRES-22 etc). He is the Editor-in-Chief of the Energy Sources Part A (Taylor&Francis), Associate Editor in the Journal of Cleaner Production (Elsevier) and Associate Editor of Solar Energy journal (Elsevier). He is editorial board member of different reputable journals such as: Energy and Buildings (Elsevier), Energy (Elsevier) Clean Technologies and Environmental Policy (Springer), International Journal of Sustainable Energy (Taylor&Francis), etc. Prof. Dr. Nižetić has published over 200 research and conference papers, as well as several techno-economic professional case studies and has visited several research and educational institutions worldwide as visiting researcher or as visiting lecturer. He has organized over twenty SI in various journals. For his research work he received several major awards including the Croatian State Prize for the research for 2016 and 2021, as well as also Rector prize for the research from the University of Split for 2018 and 2020. Based on the Stanford and Elsevier ranking list he was among 2% of the World's top cited scientist in 2019, 2020 and 2021 for single year and overall career.
