Record 27% efficiency: China’s back-contact solar cells break barriers with silicon wafers
SMRTR summary
Chinese manufacturer Longi partnered with Sun Yat-sen University to develop a new edge passivation technique that allows fragile, high-resistivity silicon wafers to achieve record 27% efficiency in back-contact solar cells. The breakthrough overcomes the manufacturing challenges that previously prevented these superior wafers from commercial adoption despite their theoretical advantages.
