Abstract

Highly efficient polymer solar cells with tandem structure are fabricated by using two excellent photovoltaic polymers and a highly transparent intermediate recombination layer. Power conversion efficiencies over 11% can be realized featured by a low-band-gap polymer with fine-tuned properties.

Keywords: conjugated polymers; efficiency; low-band-gap polymers; tandem organic solar cells.
