DOPED PHOTOVOLTAICS: ORGANIC DYE IN ZINC OXIDE INTERLAYER STABILIZES AND BOOSTS THE PERFORMANCE OF ORGANIC SOLAR CELLS

摘要

AUGUST 16, 2019 - Organic solar cells convert light into electric current. The heart of the cells is the active organic layer made of specially designed organic molecules. Here, electrons and holes, the positive counterparts of the electrons, are generated by light and travel to the electrodes to form the electric current. A recurrent problem in organic solar cell design is the matching of the material types. The electrodes are made of inorganic materials, but the active layer is organic. To join the two materials, metal oxide interlayers are introduced in many organic cell types. But in most designs, the resulting conductivities are not optimal.
