TOPCon technology mass production efficiency is expected to exceed 27%
In the context of the dual-carbon era, photovoltaics, as the main force in carbon neutrality, has attracted much attention from various industries. In recent years, as P-type PERC cells have gradually approached the theoretical efficiency development limit, the photovoltaic industry has ushered in a new iteration cycle of new and old technologies. N-type TOPCon cells have become a new technology route that the industry focuses on and is hotly discussed due to its higher conversion efficiency. At the same time, the continuous technological breakthroughs of enterprises in the field have pushed the industry to open a new era of N-type applications. Whether in the past, present or future, photovoltaic technology must develop to become more efficient, cheaper and more reliable. It is a constant and indispensable logic and principle. Since the development of the industry, the crystalline silicon technology route has shown the characteristics of a hundred flowers blooming. However, judging from the current mainstream TOPCon and heterojunction, the corresponding physical logic behind them is the same, that is, they are all passivated contacts. In the future, several technological developments will have reference , integration, but also differences. In addition, from the perspective of industry development trends, the future will definitely belong to TOPCon, and the market space is much larger than that of several other technologies. In the future, the industry will make concerted efforts to break through the double-sided TOPCon technology, and implement the application of oxide film technology on the TOPCon technology platform. The future development space of TOPCon is quite promising. At present, TOPCon technology is only used for one side. There are still many scientific questions to be answered about whether the double-sided technology will bring the theoretical efficiency to 28.7%, or whether it can reach it faster and promote the industry to achieve advanced development. solve. However, I believe that with friends from the business community and scientists, the application of more innovative technologies at TOPCon will definitely be accelerated. Throughout the development path of the photovoltaic industry, technological innovation has always been the key driver for the upgrading and development of the industry. In this era where technology is king, N-type TOPCon technology is becoming a key layout direction in the market with its series of excellent features such as low attenuation, low power temperature coefficient, high efficiency, and high bifacial ratio. In turn, how to further promote N-type technology to reduce costs and increase efficiency has become a hot topic in the industry. N-type TOPCon has the two major advantages of "high conversion efficiency, low-cost industrialization and production equipment support", and TOPCon technology is firmly chosen as the main layout direction. And through production optimization and material optimization,...
