Abstract: The use of transparent conductive oxides (TCOs) in organic solar cells applications requires deposition at low temperatures and with a limited heat treatment. This process results in high resistivity materials. To achieve practical resistivity levels, we need to replace the conventional electrode with an TCO/Metal/TCO tri-layer anode. This material yielded the desired electrical properties without a significant effect on its optical properties. The use of these tri-layer anodes in organic solar cells led to the modification in optical field distribution in the structure of the solar cells, and improves the external power conversion efficiency by maximising the absorption into the photoactive layer.
Keywords: tri-layer anodes; organic solar cells; absorption; transparent conductive oxides; TCOs; resistivity levels; electrical properties; optical properties.
