Perovskite Solar Cells

摘要: Solar energy is set to play a big role in future energy generation and achieving climate change goals [1]. At the moment, silicon-based technologies dominate the market [2]. However, recent events have illustrated the vulnerability of supply chains, and any disturbance to silicon supply lines could seriously endanger the feasibility of achieving Net Zero by 2050. The perovskite solar cell (PSC) field has progressed tremendously in the decade since the seminal papers by Miyasaka [3] and Park [4] first explored lead halide perovskites as light-absorbing materials in solar cells. Lab-scale efficiencies of> 25% have been achieved, rivalling silicon.[5] In addition, halide perovskites are finding use in multi-junction solar cells [6] and other optoelectronic applications, such as LEDs [7] and photodetectors [8]. The rapid progress on halide perovskites was largely possible due to the simplicity with which these materials can be (solution) processed, allowing many research groups around the world to contribute to the development of PSCs. Stability, lead toxicity and cost (both environmentally and economically) have drawn significant attention as factors to improve towards commercialization, and good progress has been made in all these aspects. However, further improvements are still needed for PSCs to claim a spot among the commercially successful PV technologies [9].The presence of lead in halide perovskites may be a barrier towards their commercialization, as lead is toxic and has been banned from products such as petrol and paint [10]. A popular replacement for lead is tin, which has shown promising device performance [11]. The review article “The …
