Qihang Energy Releases BC solar cell specific Additive, Replacing Nitric Acid Cleaning Process with Environmentally Friendly New Solution!

Changzhou Qihang Energy Technology Co., Ltd. recently launched an innovative product for BC (back contact) solar cells—BC additive. This product can completely replace the nitric acid process currently used in the front-side edge plating treatment before single-sided texturing of BC cells, significantly reducing environmental pollution and operational costs during production, and providing a greener, more efficient solution for the new generation of solar cell technology.

BC solar cell , due to the unique structure, traditionally require nitric acid treatment to prevent front-side plating during manufacturing. However, nitric acid is highly corrosive and poses significant environmental risks, while the disposal of waste acid substantially increases environmental protection costs. The additive developed by Qihang Energy Technology achieves high-quality plating cleaning control under nitric acid-free conditions without compromising cell performance. This innovation simplifies the production process and significantly reduces environmental pressure.
