According to Pan Wenhui, general manager of the solar cell plant, Pan Jinghui said that in 2013, Sijing will launch a P-type high-efficiency single crystal battery. Past Grain had previous initial technical cooperation with an Ashkenazi solar plant, but the battery was then developed by Shining. At present, 20% single-crystal high-efficiency batteries have entered the production phase soon. It is expected that the output will be expected in the first half of 2013 and the initial capacity planning will be 80MWp.

The 20% efficiency prediction is already close to the physical limit of P-type single crystals. If you want to further improve efficiency, you may have to rely on N-type monocrystalline solar cells that are still in the R&D stage. Due to the fact that the technology has not reached the mature stage of mass production, Sijing has not accurately estimated the timetable for launch, but Sijing will continue to invest in R&D and reduce costs. The solar energy industry said that due to the current market's relatively optimistic demand for high-efficiency products, it is expected that the P-type single crystals of Sijing will have a chance to strive for profitable space.

The solar energy market has become increasingly demanding for product conversion efficiency. Therefore, the industry's attitude towards upgrading the efficiency of mainstream P-type single-crystal or polycrystalline solar cells is quite positive, and it is believed that this is one of the key factors in the decisive battle in the near future. The more efficient Type N is actively investing in R&D. The mass production maturity of major players is still insufficient.
