TWO-COMPONENT ELECTRON-SELECTIVE BUFFER LAYER AND PHOTOVOLTAIC CELLS USING THE SAME

摘要

The present invention relates to the use of certain substituted fullerenes in optoelectronic devices, preferably in photovoltaic cells, preferably in organic photovoltaic cells especially preferred in a two-component electron-selective buffer layer of an organic photovoltaic cell to improve the efficiency of solar cells for energy generation.
