With multiple efficiency records achieved, silicon heterojunction solar cells are considered one of the most promising candidates for high-efficiency solar cell technologies in mass production. However, the high manufacturing costs, particularly the material cost associated with low-temperature silver pastes in screen-printed contacts, have resulted in rather slow uptakes of heterojunction technologies in the PV industry despite their excellent performance.

This project will focus on ultra-low silver consumption in screen-printed heterojunction solar cells with newly developed silver-lean or silver-free paste materials.
