摘要:
钛箔具有柔韧性和导电性，致密二氧化钛层可通过钛箔热氧化生成，而二氧化钛层在有机钙钛矿太阳能电池中可以作为电子传输层。本文通过使用钛箔作为支撑材料，设计并制备了柔性有机钙钛矿太阳能电池。其中通过在空气中热氧化钛箔制备致密二氧化钛电子传输层，然后利用溶液旋涂法依次在致密二氧化钛层上制备有机钙钛矿活性层、空穴传输层、透明电极层。研究表明，钛金属有机钙钛矿太阳能电池光生电压可达0.55 V，光生电流4.5 mA/cm2，该研究为制备基于柔性钛箔有机钙钛矿太阳能电池的空芯光纤太阳能电池奠定了基础。
Titanium foil is flexible and electroconductive, and a compact titanium dioxide layer can be gen-erated by thermal oxidation of it. The titanium dioxide layer can be served as the electron transport layer of an organic perovskite solar cell. A flexible perovskite solar cell was designed and fabricated by using the titanium foil as the substrate in this work. A titanium dioxide electron transport layer was formed by sintering the foil in air, then a perovskite organic active layer, a hole transport layer and a transparent electrode layer were deposited in sequence on the titanium dioxide layer via spin coating method. The as-prepared solar cell exhibits a photovoltage and photocurrent of 0.55 V and 4.5 mA/cm2, respectively. A hollow fiber structured organic perovskite solar cell is possibly established based on the flexible titanium foil solar cell.
