We fabricated the first solid state modules based on organometal halide perovskite CH3NH3PbI3-xClx using Spiro-OMeTAD and poly(3-hexylthiophene) as hole transport materials. Device up-scaling was performed using innovative procedures to realize large-area cells and the integrated series-interconnections. The perovskite-based modules show a maximum conversion efficiency of 5.1% using both poly(3-hexylthiophene) and Spiro-OMeTAD. A long-term stability test was performed (in air, under AM1.5G, 1 Sun illumination conditions) using both materials showing different behaviour under continuous light stress. Whilst the poly(3-hexylthiophene)-based module efficiency drops by about 80% with respect to the initial value after 170 hours, the Spiro-based module shows a promising long-term stability maintaining more than 60% of its initial efficiency after 335 hours.
我们使用 Spiro-OMeTAD 和聚（3-己基噻吩）作为空穴传输材料，制备了首个基于有机卤化铅钙钛矿 CH3NH3PbI3-xClx 的固态模块。采用创新工艺进行器件扩展，以实现大面积电池和集成串联连接。使用聚（3-己基噻吩）和 Spiro-OMeTAD，基于钙钛矿的模块的最大转换效率达到 5.1%。使用这两种材料进行了长期稳定性测试（在空气中，在 AM1.5G、1 个太阳光照射条件下），结果表明它们在连续光应力下表现出不同的行为。聚（3-己基噻吩）基模块的效率在 170 小时后相对于初始值下降了约 80%，而基于 Spiro 的模块显示出有前途的长期稳定性，在 335 小时后仍保持其初始效率的 60%以上。
