PV power has become an important solution of the future energy problem, however, in the manufacturing cost of mainstream crystalline silicon (c-Si) PV modules, silicon wafer accounts for a big proportion, and it is also the most energy consuming and polluting process in the PV industry chain.
Yes Solar Energy Technology develops a route with no cutting and slicing process to fabricate the super-thin and flexible c-Si solar cells. It eliminates the typical energy intensive steps in traditional production process of solar cell, such as the Siemens process, ingot, slicing, etc. The consumption of silicon material is only 1/10 of the traditional process, and the cell manufacturing energy consumption is only 1/4 of traditional c-Si technology. This kind of PV cell and module products are high-efficient, flexible and super-thin with thickness less than 40 μm. With advanced battery structure and processing technology, the component efficiency can reach as high as 22%.It also shows outstanding performance with wide angle light and weak light. The working temperature of component is 5-7 degrees lower than that of the traditional product, leading to a greatly improved energy output in the actual operating environment. Packaging on flexible substrate is achieved through the breakthrough in the process integration. By a unique intermediate-pressure-plasma process, a c-Si thin-film can be obtained with a deposition rate of 10 times faster, a production yield of 2 times higher, and a temperature of 400 ℃ lower than those typically attained by the conventional thermal chemical vapor deposition.
The product is mainly used in the differentiated market including building integration, military applications, solar powered aircraft, stratospheric airship, unmanned aerial vehicles, mobile electronics, electric vehicles, smart wear, etc. When large-scale produced in the future, it will also be applied to distributed PV power generation projects.
This technology can reduce 75% energy consumption in the manufacturing process and increase power generation by 8%. If this technology takes 15% of the global PV market in 2025, 52 million ton CO2 emission could be avoided annually.
On the basis of building and debugging the pilot production line, the company will carry out product performance improvement to achieve mass production. It will start trials in stratospheric airship and unmanned aerial vehicles, and to further develop the mobile electronics, building integration and other flexible PV applications market. In the future it will built scaled up production line with production efficiency of 22%, and explore distributed PV power plant applications.
The team is formed by world class PV experts from Silicon Valley and academic leader from CAS. It brings in extraordinary members with rich experience in equipment and technology field, mastering plenty of core intellectual property rights of mainstream photovoltaic technology. Dr. Ye Jichun, chair of the board, is the member of Thousand Young Talents Scheme of the Organization Department of the Central Committee of the CPC who has conducted deep research in thin c-Si Solar cells. CEO Dr. Liang Jianjun has 15-year experience of solar sell and masters the technology of scale production of high efficiency thin film crystal silicon cell (process and equipment). The company has gained support form 3315 start-ups, Ningbo Zhejiang.
