To fulfill the goal of high cell efficiency and low cost of “13th Five-Year” plan period and speed up the advent of the age of PV power generation at grid parity, the Technical Seminar on "13th Five-Year Plan" Efficiency Goal of Crystalline Silicon PV Cell and Whole Industry Chain jointly sponsored by National Key Laboratory of Photovoltaic Materials and Technologies and National Engineering Research Center for Photovoltaic Equipment was held today (December 1st) in Beijing. As the technological wind vane of the industry, Jinneng Clean Energy Technology Ltd. (JINERGY) was invited to attend the seminar and LI Gaofei, Technical Director of JINERGY delivered a speech titled “LCOE Drives Continuous Industrialization Technology Progress”.

Based on the “13th Five-Year Plan for Solar Energy Development” of China, it’s expected that the industrialization conversion efficiency of advanced crystalline silicon PV cell will reach 23% or more by 2020 and the price of PV generation will decrease by 50% or more in comparison with that of the year 2015, hopefully realizing the goal of grid parity on the demand side.

Driven by this favorable policy, an increasingly mature development mode, ceaseless breakthrough of cutting-edge technologies and constant innovation of various applications are seen in Chinese PV industry; especially with the appearance of emerging technologies like DWS, black silicon, PERC and HJT, the PV industry has speeded up its step into the age of high-efficiency and scale application. At the current stage, the 280W polycrystalline PV modules and 305W PERC monocrystalline PV modules of JINERGY have already realized mass production, the power of innovative HJT 72-cell bifacial PV modules has reached up to 400W, and the cell mass production efficiency has exceeded 22.5%. Relevant data show that every 1% increase in efficiency of PV modules equals to about 7% reduction in the price of PV power generation system, but the conversion efficiency of the products in the market is around 18~21% at present.

Despite all this, the scale application of industry cutting-edge technologies is still faced with lots of challenges. How does new high-efficiency cell constantly raise its efficiency and reduce its cost? How to improve PV efficiency and reduce its cost by using appropriate key cell materials and equipment?  Regarding this urgent problem, LI Gaofei believed that among the emerging innovative technologies this year the double-sided HJT super high-efficiency PV modules is an excellent solution to reduction of LCOE.

Compared with N-PERT, IBC and other emerging technologies, HJT is featured by ultra high-efficiency and double-sided generation capacity, much simpler process, bigger space for efficiency improvement after initial mass production, and more space for cost reduction. Therefore, HJT is an effective transition for PV technology to reach a high efficiency of 25%.

LI Gaofei expressed, “To speed up the breakthrough of the bottleneck in HJT mass production and promote the development of the high-efficiency cutting-edge technology, we plan to raise the stability and promote the mass production of the technology from multiple aspects like raw material, equipment and process control. Meanwhile, JINERGY also plans an in-depth cooperation with domestic superior equipment manufacturers in an effort to further reduce the mass product cost of HJT”.

LCOE has always been the ultimate goal of PV companies for a long time and it’s also the most important economic indicator to investors of power station projects. According to the industry experts, HJT has the biggest potential in improving cell efficiency among so many emerging high-efficiency technologies, so the high cost issue can be resolved soon.
