最近，通过引入卤化铅钙钛矿作为吸收剂材料丰富了薄膜光致发光领域，其允许低成本合成效率超过16%的太阳能电池。钙钛矿晶体结构和组成对材料光电性能的确切影响尚未完全了解。我们的进展报告强调了有关卤化铅钙钛矿的知识，重点是物理和光电性能。我们讨论了目前在太阳能电池中使用的钙钛矿材料的晶体和能带结构，以及晶体性质对铁电性、双极性和激子性质的影响。(C)2014年作者。
The field of thin-film photovoltaics has been recently enriched by the introduction of lead halide perovskites as absorber materials, which allow low-cost synthesis of solar cells with efficiencies exceeding 16%. The exact impact of the perovskite crystal structure and composition on the optoelectronic properties of the material are not fully understood. Our progress report highlights the knowledge gained about lead halide perovskites with a focus on physical and optoelectronic properties. We discuss the crystal and band structure of perovskite materials currently implemented in solar cells and the impact of the crystal properties on ferroelectricity, ambipolarity, and the properties of excitons.
