This summary discusses the use of Peltier devices also known as thermoelectric generators in cooling systems powered by solar panels. A Peltier device is a semiconductor device that can generate electricity from heat. By placing them on a solar panel that absorbs sunlight, a temperature difference is created in the device that creates an electric current that can be used to generate electricity. The technology is still in development but shows potential to replace cooling systems. This article explains how Peltier devices work, their integration with solar panels, and their potential for use in refrigerators
