 Information and topics: 
 PV component quality is increasingly becoming the focus of attention. Solar slice, spread, welding, laminating, and framing and other technology are likely to cause internal defects, such as cracks, broken gate, black film, debris, uneven resistivity. These invisible defects will affect the conversion efficiency, reduce reliability and shorten life, reduce the quality of quality. Our self-developed solar cell module EL tester can be quickly and easily detect the defect. The device has a high sensitivity, speed, and the results of the image, etc., is to enhance the quality of the key components of photovoltaic devices, infrared detection can fully grasp the solar internal problems, to provide a basis for improved production technology, improve product quality, the problem can be components timely repair to reduce losses.
