What is a solar cell? What are the advantages of solar cells?

Solar cells are devices that convert light energy (mainly sunlight) into electric energy. According to the principle of photovoltaic effect, that is, according to the built-in electric field of PN junction, the photogenerated carriers reach both sides of the junction separately to generate photovoltage, which is then connected to an external circuit to obtain power output. The power of solar cells is related to the intensity of light. The stronger the light, the stronger the output power.

The solar energy system has the advantages of convenient installation, expansion and disassembly. The use of solar energy is also economical, and there is no energy consumption during operation. In addition, the system is resistant to mechanical wear; Solar energy system needs reliable solar cells to receive and store solar energy. General solar cells have the following advantages:?

01) High charge absorption capacity

02) Long cycle life

03) Good charging performance

04) No maintenance required.?

Shanghai Yangmi Ultrasonic Coating System is used in fuel cell proton exchange membrane, thin-film solar cell, perovskite, microelectronics, semiconductor, nano-new materials, glass coating, biomedicine, textiles and other fields.

Ultrasonic spraying system adopts advanced spraying technology to accurately control flow rate, coating speed and deposition. Low-speed spray molding defines atomization spray as an accurate and controllable mode to avoid overspray when producing very thin and uniform coatings. Ultrasonic spraying has been proved to be a reliable and effective method to deposit photoresist on 3D microstructure, thus reducing equipment failure caused by excessive exposure of metal to etchant.
