“…This was attributed to the higher value of h for the case of internal cooling than that for the natural and external cooling methods. The reduction in temperature of the Si solar cell achieved in this study has been compared with the results obtained by other cooling methods reported in the 27 Farhanet al, 28 Firoozzadeh et al, 29 Hasan et al, 30 Krstic et al, 31 AI-Amri et al, 32 Ahmad et al, 33 Raina et al, 34 Hernandez-Perez et al, 35 literature and is summarized in Table 2. Apparently, the internal active cooling method proposed in this study offered a relatively higher temperature reduction in comparison to passive cooling and analogous external active cooling methods.…”

Photovoltaic power plants never realize their true production capacity during operation primarily because of the unavoidable heating of the solar modules under solar irradiation. Although the heating of silicon solar modules has received serious attention in the past decade, an effective and commercially viable solution is still unavailable. This study presents a detailed evaluation of the performance of a novel air-breathing internal microfluidic design (proposed in our patent application 202211050095 to the Government of India) that can be embedded in the photovoltaic modules to enable direct cooling of silicon solar cells. It was reported that a conventional silicon photovoltaic module had incurred a heat-induced fractional loss in the light harvesting efficiency of 21.4%, which was lowered to 11.3% when conventional external air cooling was employed. However, the proposed internal air cooling reduced the fractional loss in efficiency further down to 7.3% at the steady state.

“…A collective experimental and simulation study was conducted to evaluate the effectiveness of the passive cooling system to mitigate the high module temperatures. The results of the 3 month experiment (October to March) showed an average overall efficiency increase of 5.47%, with a 40% reduction in the temperature coefficient for varying outdoor conditions [27]. With the development of distributed energy systems, photovoltaic panels are being incorporated into buildings to generate electricity from solar energy [28].…”

In this experimental work, a prototype of a hybrid solar–thermal–photovoltaic (HE-PV/T) heat exchanger has been designed, built, and characterized, with rectangular geometry and 12 fins inside, to obtain better heat flow and higher performance in order to achieve a better heat transfer coefficient, reducing and optimizing the working area. The heat exchanger contains 12 photovoltaic cells connected in series, with an angle of inclination of approximately 18° towards the south and a surface area of 0.22 m2, smaller than those available on the market, which individually capture 147.05 W/m2 as a photovoltaic panel and 240 W/m2 as a solar collector. Mathematical models found in the literature from previous work were used for the electrical and thermal evaluations. The temperature of the PV cells was reduced to 13.2 °C and the thermal level of the water was raised to a temperature above 70 °C, with a photovoltaic–thermal coupling power of 307.11 W and a heat transfer coefficient of 5790 W/m2 °C. The efficiencies obtained were as follows: thermal up to 0.78 and electrical up to 0.095. The novelty of these results was achieved in a reduced space of 40% less than those reported and available on the market.
