化学调谐的无机-有机杂化材料，基于CH 3 NH3（=MA）Pb（I1-xBrx）（3）钙钛矿，已经研究了使用紫外-可见吸收和X射线衍射图案，并应用于纳米结构的太阳能电池。通过MAPb（I1-xBrx）（3）钙钛矿的化学管理带来的带隙工程可以可控地调谐以覆盖几乎整个可见光谱，从而实现彩色太阳能电池。我们展示了高效的太阳能电池，表现出12.3%的功率转换效率下的标准AM 1.5，最有效的设备，作为可调组合物的光采集器结合介孔二氧化钛膜和空穴导电聚合物的结果。我们相信，本文中强调的工作代表了实现低成本，高效率和长期稳定的彩色太阳能电池的一步。
Chemically tuned inorganic-organic hybrid materials, based on CH3NH3(=MA)Pb(I1-xBrx)(3) perovskites, have been studied using UV-vis absorption and X-ray diffraction patterns and applied to nanostructured solar cells. The band gap engineering brought about by the chemical management of MAPb(I1-xBrx)(3) perovskites can be controllably tuned to cover almost the entire visible spectrum, enabling the realization of colorful solar cells. We demonstrate highly efficient solar cells exhibiting 12.3% in a power conversion efficiency of under standard AM 1.5, for the most efficient device, as a result of tunable composition for the light harvester in conjunction with a mesoporous TiO2 film and a hole conducting polymer. We believe that the works highlighted in this paper represent one step toward the realization of low-cost, high-efficiency, and long-term stability with colorful solar cells.
