开发了低温处理（100 °C）的碳糊作为无空穴导体的钙钛矿/TiO 2异质结太阳能电池的对电极材料以替代贵金属材料。在优化的条件下，该碳对电极的PCE值达到了8.31%。电化学阻抗谱表明低温处理碳对电极具有良好的电荷传输特性。此外，这种基于碳对电极的钙钛矿太阳能电池在800 h以上表现出良好的稳定性。
Low-temperature-processed (100 °C) carbon paste was developed as counter electrode material in hole-conductor free perovskite/TiO2 heterojunction solar cells to substitute noble metallic materials. Under optimized conditions, an impressive PCE value of 8.31% has been achieved with this carbon counter electrode fabricated by doctor-blading technique. Electrochemical impedance spectroscopy demonstrates good charge transport characteristics of low-temperature-processed carbon counter electrode. Moreover, this carbon counter electrode-based perovskite solar cell exhibits good stability over 800 h.
