Yes, there are new technologies being developed for cooling solar panels. One notable development is radiative cooling technology, which has been explored by researchers in China. This technology involves creating a chamber made of materials like ethylene-tetrafluoroethylene (ETFE) and polydimethylsiloxane (PDMS) to achieve radiative cooling without power consumption. The setup allows for a cooling power density of up to 40 W/m², although it slightly reduces photovoltaic power output to around 103.33 W/m² from 120 W/m² on a bare solar cell.
Another approach is improving the efficiency and design of solar panels themselves, such as bifacial solar panels and floating solar farms. Bifacial panels can capture sunlight from both sides, increasing efficiency, especially in environments with high albedo surfaces. Floating solar farms benefit from water’s cooling effect, enhancing efficiency by up to 15% compared to ground installations.
These technologies aim to optimize solar panel performance and efficiency, although they may not be specifically designed as cooling systems but contribute to managing heat effectively.
