AI Technical Summary

Technical Problem

The grid design of existing solar cells is unreasonable, which leads to an increased shading effect, preventing light from being effectively refracted and reflected, increasing contact resistance, and affecting photoelectric conversion efficiency and output power.

Method used

The side design of the grid lines is optimized so that the tangent at the set height forms an angle of less than 90° with the battery body, and the aspect ratio of the grid lines is controlled to be 35%-85%. The shape and height of the grid lines are optimized by combining screen printing technology, and multiple anti-reflective layers are used to reduce light reflection and scattering.

Benefits of technology

It improves photoelectric conversion efficiency, reduces contact resistance and series resistance, enhances the effective incidence and utilization of light, and extends battery life.
