LONGi heterojunction back-contact solar cell reaches 27.81% efficiency

LONGi announced that its upgraded Hi-MO 9 solar panel with back-contact “HPBC 2.0” technology has reached 24.8% efficiency with a maximum power output of 670 W. By integrating zero busbars with half-cell architecture, LONGi was able to boost the modules power output by 10 W. The optimized rear-side grid design elevates the panel’s bifaciality to…
