High Performance Mono-like Silicon Solar Cells and Modules by Using Industrial Mass Production Technology

摘要

In this paper, we proposed the high performance mono-like silicon solar cells by using industrial mass production technology. Using an optimized laser opening ratio and back side pattern design on commercially available 156 mm × 156 mm p-type Czochralski-grown crystalline mono-like silicon wafers, the best cell efficiencies of 18.8% without passivation rear side dielectric and 20.6% with passivation rear side dielectric are demonstrated. The series resistance losses are reduced in module production processes by optimizing the module design and materials, the maximum module power of up to 285 W and 19.17% aperture area efficiency are achieved. Besides, the mono-like solar cells and modules all passed the IEC 60904 and IEC 61215 test criteria from ITRI measurement.
