Organo-metal lead halide perovskite solar cells (PSCs) attract attention due to their low cost and high power conversion efficiency. Some weak points of this technology are short lifetime, instability, and expensive metal electrode deposition. Eliminating the unstable hole transport layer (HTL) and using carbon-based materials as the counter electrode would address both. In this work, we present a cradle-to-gate life cycle assessment of two HTL-free PSC designs, which use solution phase deposition to achieve mesoscopic and planar structures. Environmental impacts of producing 1 m2 PSCs are converted to impacts per kWh electricity generation assuming 5 years of operational lifetime. We find that major impacts come from fluorine doped tin oxide (FTO) glass patterning due to the electricity consumption of FTO patterning and glass cleaning processes. Even though the electricity consumption when manufacturing both PSCs is similar, their different efficiencies make the environmental impacts per kWh of electrici...

无空穴传输的平面介观钙钛矿太阳能电池的生命周期评估

有机金属卤化铅钙钛矿太阳能电池（PSC）因其低成本和高功率转换效率而备受关注。该技术的一些弱点是寿命短、不稳定性和昂贵的金属电极沉积。消除不稳定的空穴传输层 (HTL) 并使用碳基材料作为对电极可以解决这两个问题。在这项工作中，我们对两种无 HTL 的 PSC 设计进行了从摇篮到门的生命周期评估，这些设计使用溶液相沉积来实现介观和平面结构。假设运行寿命为 5 年，生产 1 平方米 PSC 的环境影响将转换为每千瓦时发电量的影响。我们发现，由于 FTO 图案化和玻璃清洁过程的电力消耗，主要影响来自掺氟氧化锡 (FTO) 玻璃图案化。
