Development of Efficient and Stable Perovskite Solar Cell with Safe-to-Use

Description

Energy needs and environmental sustainability is one of the greatest challenges our Planet is facing. Presently, over 85% of the world energy is provided by non-renewable fossil fuels with concealed consequences on the health and the environment. Among various emerging photovoltaic technologies, metal halide perovskite solar cells (PSCs) have attracted enormous attentions from both academic and industrial communities in the past few years owing to their great promise of realizing low-cost, high-performance printable solar cells that can help address the scalability challenges for affordable clean energy. Our proposal aims at establishing the technology base for producing high efficiency, stable, and safe-to-use PSCs for renewable energy applications, with particular focuses on addressing the stability and toxicity issues of PSCs. In parallel, we will systematically resolve the key scientific and technical challenges in fine-tuning rheological characteristics and compatibility of perovskite precursors with defect passivation of the perovskite films and optimize the fabrication processes of highly efficient and stable PSCs that will meet the commercial application requirements. At the end, we will demonstrate high efficiency (PCE≥25% with area of 0.1 cm2 and ≥ 23% with area of 1 cm2), stable (operation under ambient air >1000h), and minimized lead leakage in the derived PSCs.
