Gigawatt-scale tandem PV cell output by 2022?
Frank van Mierlo, the CEO of 1366 Technologies, is a betting man. And he’s betting your humble narrator that high-efficiency tandem solar cells are the near-term commercial future of solar.
Focus on the negatives: A new path to highly efficient tandem cells
Scientists in the U.S. and South Korea have identified what could be a new route to high-efficiency perovskite-silicon tandem solar cells. Through engineering negatively charged particles in the passivation layer, the group made a tandem cell with 26.7% efficiency. With further tweaks to the silicon layer they expect to be able to surpass 30%.
