GCL-Poly Energy Holdings Limited (“GCL-Poly”, “the Group”, stock code: 3800.HK), is pleased to announce that the Group has successfully developed the high efficiency multicrystalline wafer “GCL Multi-Wafer S1+”. Customer feedback after trial run: the average conversion efficiency of “GCL Multi-Wafer S1+” reached 17.6%, with an increase of 0.5-0.7% when compared with the current benchmark. 250+W module can now be comprehensively produced from the existing production lines. “GCL Multi-Wafer S1+”can help to lower the solar power generation cost by more than 2% and provide the most competitive products to our cell and module customers, resulting in making significant contribution to cost reduction of the whole solar system. “GCL Multi-Wafer S1+” redefines “high efficiency multicrystalline wafer” and leads to the era of “high efficiency” of the global solar industry.

The development of “GCL Multi-Wafer S1+”is based on the innovative apprehension of the theory of silicon material, on which new design of thermal field and precise process development are based. GCL Multi-Wafer S1+” is made from electronic grade polysilicon materials produced by GCL-Poly under the most stringent quality control in the industry. Compared with ordinary multicrystalline wafer, “GCL Multi-Wafer S1+” has improved the microstructure and controlled precisely crystal defects such as dislocations, stacking faults and grain boundaries. At the same time, “GCL Multi-Wafer S1+” has the characteristics of low concentration of carbon, oxygen and metal impurity, and also high minority carrier lifetime as well as uniform doping profile.

From now on, GCL-Poly will continue to improve the conversion efficiency of GCL Multi-Wafer and other products through continuous technical research and development. GCL-Poly expects that the output of GCL Multi-Wafer modules (60 units, 156 x 156mm) and GCL Quasi-Mono Wafer modules (60 units, 156 x 156mm) will reach 270W and 285W respectively through the successful adoption of the existing technology achievements.

Mr Shu Hua, Executive President of GCL-Poly, said: “Technological innovation is the core driving force of the survival and development of enterprises, and is the only way to achieve grid parity for the global solar market. Adhering to this philosophy, and after the release of “GCL-ASCS-880” advanced ingot furnace system and “GCL Quasi-Mono Wafer” products, GCL-Poly launched the high efficiency “GCL Multi-Wafer S1+” products, reflecting GCL-Poly’s commitment of “providing the most valuable products and services to our customers” and demonstrates our role as an industry leader in the research and development of new products. GCL-Poly will always be committed to the research and development of top-notch solar technology, which can strongly promote grid parity and change the future of mankind by means of green energy.”
