Lignin-based silver paste solar cell hits 25.96% efficiency
Original: Heterojunction solar cell built with biomass lignin-based silver paste achieves 25.96% efficiency
Researchers have built a heterojunction solar cell using a silver paste derived from biomass lignin, achieving a power conversion efficiency of 25.96%. The result, reported by pv magazine, suggests wood-derived materials could replace conventional petroleum-based pastes in high-efficiency solar manufacturing, cutting costs and the carbon footprint of photovoltaic production while maintaining performance close to standard silver paste cells.
Why now: The use of a cheap, renewable lignin-based paste at near-record efficiency offers a promising route to greener, lower-cost solar cell production.
