Do you understand component packaging technology?
SNEC site Mingguan n-type battery packaging overall solution, leading the upgrade of component packaging technology From May 24th to 26th, the world's most influential photovoltaic event - SNEC Photovoltaic Exhibition was held in Shanghai. At the scene, International Energy Network visited Mingguan New Materials. 2023 is the year when n-type technology will be fully scaled up. Enterprises have launched n-type products one after another, and hundreds of gigawatts of production capacity are under construction. The entire photovoltaic industry chain is ready for upstream silicon materials, silicon wafers, batteries, modules, and even backplanes, adhesive films, and silver pastes. China's photovoltaic industry is moving towards the n-type era in an all-round way. Then, why does China’s photovoltaic industry rapidly carry out technological iterations, what technical pain points still exist in the n-type era, and how companies face various impacts brought about by technological iterations? I met the relevant person in charge of Mingguan New Materials and listened to him reveal the answers to the above questions. In the n-type era, technology iterations are not limited to batteries The photovoltaic industry is a complete industrial chain. The emergence, development, and further advancement of any technology into the mainstream technology of the industry requires the cooperation of the upstream and downstream of the industrial chain. At the same time, the photovoltaic industry is a very fine-grained industry. Technology upgrades and then technical iterations are completed through bit by bit technological progress, and the process from quantitative change to qualitative change is completed. Just like the current industry hotspot - n-type technology, many people may turn their attention to the field of batteries and modules, focusing on the conversion efficiency of TOPCon or HJT batteries and modules, while ignoring that the improvement of battery and module efficiency is only the final result . In this process, silver paste, adhesive film, and backplane have also made important contributions, and technology upgrades and iterations are also required in the n-type era. According to the person in charge of Mingguan, although the n-type battery technology has many advantages such as high conversion efficiency, high bifaciality, low attenuation, and low temperature coefficient, the special structure of the n-type battery has great impact on the anti-PID performance of packaging materials, Corrosion resistance, water resistance, adhesion and other aspects have more stringent requirements. The packaging materials used in the past for p-type components are not enough to meet the needs of the n-type era. In order to shift the photovoltaic cell module technology from p-type to n-type with higher efficiency, it is necessary to solve the problem of packaging materials, and to have a packaging solution suitable for n-type cell modules. This is a real problem facing th...
