On November 4, Shanxi Taixin Economic Zone (Xinzhou District) 14GW Photovoltaic Cell Production Base Project BC High-efficiency Photovoltaic Cell Production Line Intelligent Transformation and Upgrading Project Evaluation Document was announced.
According to the announcement, in order to seize the opportunity of BC technology industrialization, Yidao New Energy Technology (Xinzhou) Co., Ltd. decided to start the intelligent transformation and upgrading project of BC high-efficiency photovoltaic cell production line in the 14GW photovoltaic cell production base of Taixin Economic Zone (Xinzhou District).

The project will upgrade the original process to meet the DBC process requirements through the transformation of production equipment (old, obsolete and new), and upgrade 26 TOPCON production lines to 24 DBC back contact high-efficiency crystalline silicon battery production lines.
Although the number of the processed cells is reduced, the conversion efficiency of the BC high-efficiency cell is not less than 27.8% due to the increase of the power of a single cell. After the completion of the project, the total production capacity will remain unchanged at 14 GW .
This technical transformation project is carried out in the existing factory area of Yidao New Energy Technology (Xinzhou) Co., Ltd., with a total investment of 118111 million yuan and a construction period of about 12 months.
At present, there are two battery production workshops in the project: 13 main battery production lines are arranged in each workshop, and the production scale is 7 GW Topcon monocrystalline solar cells.
