The work addresses a key challenge in fully printed perovskite photovoltaics with non-reflective carbon electrodes: the formation of bottom voids in thick perovskite layers (>600 nm), which are detrimental to light absorption and significantly compromise device performance. In collaboration with the phase-field simulation group led by Prof. Jens Harting (HIERN), we demonstrate that these voids originate from trapped residual solvents—resulting from nanocrystal aggregation at the liquid–vapor interface during the drying process.To overcome this, we propose a two-dimensional (2D) perovskite layer-assisted growth (2D-LAG) strategy that promotes heterogeneous nucleation at the substrate interface. This accelerates the crystallization of three-dimensional (3D) perovskites and prevents solvent entrapment. The strategy enables the formation of highly crystalline, void-free perovskite films exceeding one micrometer in thickness and facilitates the fabrication of high-efficiency, fully printed devices.
Congratulations to Shudi and co-authors on this outstanding achievement!
