一种钙钛矿太阳能电池及其制备方法
摘要：
本发明公开了一种钙钛矿太阳能电池及其制备方法，钙钛矿太阳能电池依次包括导电玻璃层、致密二氧化钛膜、多孔二氧化钛膜、甲胺铅碘多晶膜、空穴传输材料层及金属电极层，特点是：多孔二氧化钛膜是锌掺杂的，掺杂后锌原子与钛原子的摩尔比为0.1%~0.4%∶1；优点是：使用含锌掺杂的多孔二氧化钛作为钙钛矿太阳能电池的光阳极，能够通过锌掺杂改变二氧化钛的导带，使二氧化钛导带下移，从而使得作为钙钛矿吸光层的甲胺铅碘的导带与锌掺杂的二氧化钛的导带之间间隙变大，使电子更容易注入和通过，从而能够提高钙钛矿太阳能电池的光电转换效率。
摘要（英）：

The invention discloses a perovskite solar cell and a preparation method thereof. The perovskite solar cell comprises a conductive glass layer, a compact titanium dioxide film, a porous titanium dioxide film, a methylamine lead iodine polycrystalline film, a hole-transport material layer and a metal electrode layer in sequence. The perovskite solar cell is characterized in that the porous titanium dioxide film is Zn-doped, and after doping, mole ratio between zinc atoms and titanium atoms is 0.1%-0.4%:1. The perovskite solar cell has the advantages that the Zn-doped porous titanium dioxide is utilized as a photo anode of the perovskite solar cell; a titanium dioxide conduction band can be changed through Zn-doping, and the titanium dioxide conduction band is allowed to move down, so that a gap between a methylamine lead iodine conduction band serving as a perovskite light absorption layer and Zn-doped porous titanium dioxide conduction band is enlarged, electrons are allowed to be easier to inject and pass, and photoelectric conversion efficiency of the perovskite solar cell can be improved.
