SMM News: recently, the efficient heterojunction HIT project plant that has attracted much attention from investors has been completed. Recently, the equipment of the first phase of the heterojunction battery project has entered the market one after another, and gradually entered the installation and commissioning, and the heterojunction module project has been put into production. Aikang Technology subsidiary Aikang Optoelectronics Phase I project (2GW high efficiency heterojunction batteries and modules) has invested 570 million yuan.

Aikang Science and Technology High efficiency Solar Cell Project was jointly invested by Zhejiang Energy Group and Aikang Technology in June 2018, with a total investment of 10.6 billion yuan and a total production capacity of 5GW, which is planned to be completed in three years, with an estimated annual sales income of 12 billion yuan. Its main products are high-efficiency heterogeneous crystalline silicon photovoltaic cells and double glass tile photovoltaic modules.

It is understood that the company in the original frame, bracket and other advantages of manufacturing, from 2010 began to cultivate HIT heterojunction core technology, efforts to create Zhejiang Changxing, Jiangxi Ganzhou efficient photovoltaic cell and module production base, forming a "Zhangjiagang, Ganzhou, Changxing" three development pattern, and to HJT battery module project as the core, ahead of time layout of the next round of photovoltaic technology iteration of the main position.

At the 2020 China New Energy Summit Forum held this week, Wang Wenjing, director of the Solar Cell Research Office of the Institute of Electrical Engineering of the Chinese Academy of Sciences, said that compared with PERC cells, heterojunction cells have competitive advantages such as high efficiency, large size, simple process, low attenuation and efficiency, and can achieve 25 per cent battery conversion efficiency within a year or two.

In addition, analysts believe that HIT technology is a new process after PERC, and the key point of its industrialization tide is the end of 2020, while HIT heterojunction components have outstanding advantages such as strong profitability, high conversion efficiency and low attenuation rate, so they are very popular all over the world. According to the calculation of SOLARZOOM New Energy think Tank, although the cost of HIT components is about 0.17 yuan / W higher than that of PERC, it is about 1.12 yuan / W higher than the price excluding tax. On this basis, HIT components can achieve a net profit of 710 million yuan / GW more than PERC components.
