In this article, the authors reviewed the modern technologies for manufacturing transparent, bifacial, flexible panels and other similar solutions. Passive or active cooling solutions, with air or water vapor, or energy storage solutions are analysed. If the passive air cooling of the photovoltaic panel can achieve a reduction of its temperature by only 10 °C, by active cooling, a cooling with over 30 °C can be obtained. These technologies are aimed to improve the energy efficiency of photovoltaic panels. The article presents examples of photovoltaic panels’ own applications, as well as hybrid PV, realizing the cooling of the PV panel and the recovery of the thermal energy in the form of hot air or hot water, with good efficiency.
