  Solar energy semiconductor refrigeration by DC Freezer Exporter. Solar semi-conductor refrigeration is a special refrigeration method that uses electric energy generated by solar cells to supply semi-conductor refrigeration devices to realize heat transfer. The theoretical basis of semiconductor refrigeration is the thermoelectric effect of solids, that is, when direct current passes through a circuit composed of two different conductive materials, heat absorption or heat release occurs at the junction. How to improve the performance of materials and find more ideal materials has become an important issue for solar semiconductor refrigeration. Solar semiconductor refrigeration is widely used as a cooler for electronic devices and instruments in the fields of national defense, scientific research, medical and health, or for low-temperature measuring instruments and equipment, or to make small thermostats. At present, the efficiency of solar semiconductor refrigeration devices is still relatively low. The COP is generally around 0.2 to 0.3, which is much lower than compression refrigeration.
