High-performance ternary organic solar cells with thick active layer exceeding 11% efficiency

We present a novel ternary organic solar cell with an uncommonly thick active layer (similar to 300 nm), featuring thickness invariant charge carrier recombination and delivering 11% power conversion efficiency (PCE). A ternary blend was used to demonstrate photovoltaicmodules of high technological relevance both on glass and flexible substrates, yielding 8.2% and 6.8% PCE, respectively.
