摘要
The growing demand for renewable energy has spotlighted photovoltaics (PVs), particularly perovskite solar cells (PSCs). However, current processes for manufacturing PSCs rely on high-temperature annealing and intricate post-treatments, thereby limiting their applicability. To address this challenge, we introduce a simple approach to produce high-quality perovskite films at room temperature (RT) by precisely regulating the perovskite composition (Csx(FA0.92MA0.08)1−xPb(I0.92Br0.08)3) with the addition of an organic linker (oleylamine, OAm). This method enabled phase conversion to the stable α-phase without thermal annealing, as confirmed by in situ X-ray monitoring. The optimized Cs10+OAm device achieved impressive efficiencies of 23.2% (24.4% with an anti-reflective coating), surpassing efficiencies attained by previous room/low-temperature-processed PSCs. Additionally, we demonstrated the feasibility of fabricating perovskite films on unconventional substrates (natural leaves), showcasing the potential for versatile applications. These findings offer insights into stabilizing the perovskite structure at RT, promising advances in PV technology and sustainable light energy utilization.
