Article Synopsis
- All-perovskite tandem solar cells are promising for high performance and affordability, crucial for market entry.
- Researchers developed a new triple-halide perovskite with a 1.8 eV bandgap, enhancing tandem cell performance through a special surface treatment using piperazinium iodide (PI).
- This innovation resulted in improved charge carrier properties and efficiency, leading to a tandem solar cell achieving a certified efficiency of 27.5%.
A variety of different synthesis methods for the fabrication of solar cell absorbers based on the lead halide perovskite methylammonium lead iodide (MAPbI, MAPI) have been successfully developed in the past. In this work, we elaborate upon vacuum-based dual source co-evaporation as an industrially attractive processing technology. We present non-stationary processing schemes and concentrate on details of co-evaporation schemes where we intentionally delay the start/end points of one of the two evaporated components (MAI and PbI).
