Solar energy is one of the most promising energy sources for the near future, which will require a large number of renewable electricity sources. The ever-growing population of the planet needs a huge amount of resources every day, which unfortunately are not unlimited on Earth. No matter how useful modern technology for manufacturing solar modules is for the global energy industry, devices from the beginning of the 21st century are unable to generate electricity at night. However, according to an article published on sciencealert.com, scientists have recently been able to design panels that can work almost around the clock.
Can solar panels generate electricity at night?
Solar energy is one of the latest trends in modern science. As the main equipment for converting solar energy into electrical energy, experts most often use solar panels and solar panels, which can be useful not only in industry but also for domestic needs. However, modern devices for generating solar energy cannot work effectively at night for seemingly completely natural reasons. However, a new study suggests that the invention of scientists at the University of California at Davis can solve a similar obstacle to humanity's path to a powerful source of renewable energy. Specially developed photovoltaic cells can generate a quarter of the energy they produce during the day.

To achieve this, experts want to include heat radiation cells – mechanisms that can generate energy thanks to so-called radiation cooling. Developed mechanisms help that infrared or thermal radiation leaves the cell and generates a small amount of energy during this process. At present, heat radiation elements are already undergoing the tests necessary for their implementation in production, which are mainly used to convert waste heat into engines.

Scientists are currently trying to find the optimal combination of materials and electronics to use the night sky as a heat sink to develop the most efficient solar module. The researchers argue that solar parks with thermal radiation elements can produce up to 50 watts per square meter, which should not only help to increase the efficiency of existing solar modules, but also when using unique devices under conditions where there are no alternatives to power sources. The rational use of photonics, optics and material science in the form of improved solar collectors can also create the first human settlements on the moon and Mars.
