采用定向二氧化钛纳米线(TNW)阵列作为晶化支架，对太阳能电池光吸收材料二维丁基铵钙钛矿晶体取向进行了控制。通过调节TnW阵列旋涂结晶条件，在TnW阵列中嵌入垂直取向的钙钛矿膜，获得了最高转换效率的二维钙钛矿基太阳电池。
Crystal orientation of two-dimensional (2D) butylammonium lead iodide perovskite as a light absorber of solar cells was controlled by use of oriented TiO2 nanowire (TNW) array as a scaffold of crystallization. Tuning crystallization conditions in spin-coating on TNW array, the highest conversion efficiency of the 2D perovskite-based solar cell was obtained with a vertically oriented film of perovskite embedded in the TNW array.
