Rapid Fabrication of Large-area Stable PSC with High Conversion Efficiency
DescriptionWhile metal halide perovskite solar cells (PSC) presently attract enormous research interest because of their high-power conversion efficiency (PCE) and low fabrication costs, their practical development is hampered by discrepancies in large-area devices due to lack of knowledge on charge transfer dynamics and precursor stability in translating fabrication from inert to ambient environment. The project proposes multifunctional strategy for controlling nucleation and crystallization of large-area perovskite through solvent and additive engineering using slot-die coating technology complimented with near-infrared heating. The underlying mechanism of the proposed approach will be evaluated by probe microscopy and crystallographic precision techniques. Furthermore, the dynamics of the photo-generated charge carriers will be studied by ultrafast transient absorption spectroscopy techniques to analyze and address the efficiency loss in the large-area PSC. This research will provide both fabrication and mechanism guidance for efficient large-area perovskite with high performance, which represents a significant step toward industrial production and commercialization.
