Organic solar cells reach 20.21% efficiency with pseudo-planar heterojunction design

Scientists have created pseudo-planar heterojunction organic solar cells with one of the highest efficiency scores ever for that structure. To do so, they had to overcome solvent-induced swelling and erosion of the donor. Their solution: a novel interfacial buffering strategy. The post…
