A construction process for improving XBC battery efficiency

Abstract

The invention discloses a construction process for improving the efficiency of XBC cells, including the following steps: selection and preparation of insulating paste; electrode pattern design and arrangement, by designing positive and negative electrode patterns on the back of photovoltaic XBC cells, the positive and negative electrode patterns are arranged in an alternating manner to maximize the area between electrodes and reduce series resistance; coating of insulating paste; main grid printing; cell packaging and testing. The process of the invention can effectively avoid short circuits between electrodes and shorten the transmission distance of carriers by using insulating paste to isolate the positive and negative electrodes on the back during the manufacturing process of the cell, thereby improving the conversion efficiency of the cell and simplifying the manufacturing process.
