Abstract

This study introduces an optical approach to enhance the open-circuit voltage (Voc) in organic solar cells (OSCs) characterized by high radiative recombination. By exploring various one-dimensional structurations of the OSC device, we reduce Boltzmann losses arising from the mismatch between absorption and emission cones. This innovative method leads to a significant Voc enhancement, achieving an increase of approximately 30 mV through optical means. Furthermore, our findings establish a novel route in the development of planar geometry single-junction solar cells, surpassing the power conversion efficiency values set by the Shockley-Queisser limit.
