Article Synopsis
- - The fabrication of halide perovskite (HP) solar cells typically faces challenges due to incompatibility between material layers, but a new method called lamination allows for separate processing of half-stacks that are bonded together to create the final device.
- - This study focuses on how different lamination conditions (temperature, pressure, and time) affect important properties like bonding quality, grain size, and light emission in the solar cells.
- - The research finds that a lamination temperature of 150 °C is optimal, leading to over 95% bonding success and improved grain size and light emission, ultimately impacting the performance of the solar cells.
Transport layer and interface optimization is critical for improving the performance and stability of perovskite solar cells (PSCs) but is restricted by the conventional fabrication approach of sequential layer deposition. While the bottom transport layer is processed with minimum constraints, the narrow thermal and chemical stability window of the halide perovskite (HP) layer severely restricts the choice of top transport layer and its processing conditions. To overcome these limitations, we demonstrate lamination of HPs─where two transport layer-perovskite half-stacks are independently processed and diffusion-bonded at the HP-HP interface─as an alternative fabrication strategy that enables self-encapsulated solar cells.
