 The abstract describes the use of M003 doping in carbon nanotube top electrodes for perovskite solar cells, which improves p-doping, energy-level alignment, and hole transport. The optimal layer thickness is determined to be 8 nanometers, resulting in a substantial decrease in sheet resistance without damaging the perovskite film. When coated with Spiro-Meo-TAD, M003 crystallizes on carbon nanotubes and enhances hole collection. Semi-transparent perovskite solar cells with M003 doped carbon nanotube electrodes have a power conversion efficiency of 17.3% with a transmittance of approximately 60%. The use of these perovskite solar cells in tandem structures with silicon solar cells is predicted to result in a device efficiency of 23.7%, exceeding that of conventional indium tin oxide-based tandem solar cells.
