At very serious condition where the simulated heavy rain lasted for 72 h, lead in perovskite films entirely leached out with the leaking amounts of 0.54 g/m 2 for the damaged PSCs both without encapsulation and with only the bottom glass encapsulation (Jiang et al., 2019).
Although perovskite solar cells have tremendous advantages such as high photovoltaic performance, low cost and facile solution-based fabrication, the issues involving lead could be one of the main obstacles for its commercialization and large-scale applications.
Despite the excellent power conversion efficiencies of perovskite solar cells (PSCs), lead toxicity is one of the main concerns for this emerging photovoltaics technology.
The presence of toxic lead enables high photoconversion efficiency of perovskite solar cells but poses environmental and human health concerns. Here the authors address the issues by introducing a cost-effective TiO2 absorption layer through a scalable process.
