“…To quantify this effect, calculations based on the energy conservation were performed without consideration of thermal conduction within the solar panel. The panel temperatures were calculated using the energy equation of the solar cell, as shown in . The solar irradiances are set the same with those in experiments.…”

“…in tropical regions or in summer seasons) generally suffer from more efficiency loss. This efficiency loss could offset the efficiency improvement gained as a result of the PV technical development during the last two to three decades . This motivates the development of cooling strategies so that the PV cell efficiency loss can be reduced and more energy yield can be obtained.…”

Summary With temperature increasing, the photovoltaic efficiency of solar cells is reduced significantly. Such an efficiency loss may offset the efficiency improvement because of the development of the photovoltaic technology. This paper provides a novel approach for efficiency loss recovery of solar cells. Specifically, a nano‐coated heat pipe plate was integrated with the solar panel to remove heat from the hotspots on solar cells. This study concerns the indoor experiments of a commercial solar cell thermally managed with a heat pipe plate. The temperature rise and non‐uniformity on the solar panel were quantified in different light irradiances. With thermal management by the heat pipe plate, the solar panel shows a temperature‐rise reduction of 47–50%. This implies that half of the efficiency loss of the solar cell can be recovered. In addition, the temperature variation within the solar panel is reduced to 1.0–2.5 °C, which is beneficial in prolonging the longevity of the solar cell. In the experiments, the heat pipe plate can provide a cooling flux of 380 W/m2 with light irradiance below 1000 W/m2. By incorporating the heat pipe plate with a water jacket, the heat removal flux could be improved to 600 W/m2, leading to a solar cell temperature of a few degrees higher than the ambient.

“…Based on the experimental data, the cooling power by the heat-pipe plate is evaluated using the energy balance method 35 . The results indicate that the cooling power of the heat-pipe plate increases simultaneously with the temperature rise of the solar cells, which is stabilized as 250–260 W/m 2 with a steady cell temperature of approximately 39.5 °C ( Fig.…”

Solar photovoltaics (PV) are emerging as a major alternative energy source. The cost of PV electricity depends on the efficiency of conversion of light to electricity. Despite of steady growth in the efficiency for several decades, little has been achieved to reduce the impact of real-world operating temperatures on this efficiency. Here we demonstrate a highly efficient cooling solution to the recently emerging high performance plasmonic solar cell technology by integrating an advanced nano-coated heat-pipe plate. This thermal cooling technology, efficient for both summer and winter time, demonstrates the heat transportation capability up to ten times higher than those of the metal plate and the conventional wickless heat-pipe plates. The reduction in temperature rise of the plasmonic solar cells operating under one sun condition can be as high as 46%, leading to an approximate 56% recovery in efficiency, which dramatically increases the energy yield of the plasmonic solar cells. This newly-developed, thermally-managed plasmonic solar cell device significantly extends the application scope of PV for highly efficient solar energy conversion.

“…The solar cell is currently the most prevalent solar energy power conversion device since it can directly convert solar radiation into high-grade electrical energy. However, a photovoltaic (PV) panel consisting of solar cells exhibits a notable temperature rise as it is exposed to solar radiation [1], which causes PV efficiency degradation and electrical power output loss [2]. Specifically, PV efficiency would decrease by about 0.5% as the temperature of the crystalline silicon cells increased by 1℃ [3].…”
