无铅、全无机钙钛矿的开发是克服现有有机/无机杂化卤化铅吸收层稳定性限制和环境危害的潜在途径。与所有薄膜太阳能电池一样，具有宽处理窗口的可扩展卷对卷方法是可取的。在这里，我们提出了有希望的初始材料和光电器件的气相沉积CsGeI3。钙钛矿是由堆叠的二元金属碘化物前体进行简单退火制备的。所得钙钛矿的光学带隙为1.7 eV。初始测试装置的效率为0.58%，VOC为445 mV。
The development of lead-free, all inorganic perovskites is a potential pathway to overcoming the stability limitations and the environmental hazards associated with the dominant organic/inorganic hybrid lead halide based absorber layers. As with all thin films solar cells, scalable roll-to-roll methods with broad processing windows are desirable. Here, we present promising initial materials and photovoltaic device results on vapor deposited CsGeI3. The perovskite was fabricated by a simple anneal of stacked binary, metal-iodide, precursors. The resulting perovskite had an optical bandgap of 1.7 eV. An initial test device had an efficiency of 0.58%, and 445 mV VOC.
