Recently, Shanxi's first photovoltaic module manufacturer Jinneng Clean Energy Technology Co., Ltd. announced that its innovative research and development of single crystal PERC back-passivation battery pilot test efficiency of 21.36%, higher than the industry average efficiency of 20.6-20.9% of similar technologies To reach the world's leading level. This is of great strategic importance for further accelerating the development and application of Shanxi's new energy industry, upgrading the high-end manufacturing of new energy, and integrating it with the international advanced level.
At present, Shanxi Province is struggling to step out of the "one coal alone" dilemma, and vigorously cultivate the development of photovoltaic power generation, wind power and other new energy industries, in order to build a new national integrated energy base. The newly released data from Shanxi Electric Power Company also indicates that its new energy industry is developing rapidly. As of December 20, 2015, Shanxi Power Grid accumulated annual photovoltaic power generation amounted to 637.54 million kWh, and new energy generation reached 10.05671 trillion kWh. It accounts for 5.61% of the total amount of electricity generated by direct power generation in Shanxi Power Grid.
According to the person in charge of research and development of the company's technology, back passivation technology is mainly to grow a layer of aluminum oxide film on the back surface of the battery by atomic layer deposition method, and the back surface is well-blunted through the negative charge-characteristic characteristics of the aluminum oxide film. At the same time, the laminated film grown on the back surface is positioned and opened by a laser groove method, so that the carrier can be effectively collected after metallization. This technology product features higher photoelectric conversion efficiency, higher open circuit voltage, and better low-light response. (Reporter Zhou Wenkui’s correspondent Li Yang)
