Solution-processed All-perovskite Multi-junction Architectures for Flexible and Printable Solar Cells

This project entails the design and fabrication of Solution-processed All-perovskite Multi-junction solar cell Architectures (SAMA) that can be integrated with printable solar cell technology.

Using knowledge obtained at Monash University, Melbourne and Commonwealth Scientific and Industrial Research Organization (CSRIO), we plan to fabricate all-perovskite tandem architectures that are entirely solution-processable. This feature allows for compatibility with existing large-scale, high-throughput printable fabrication techniques.

Sequential deposition of solution-processed semiconductor layers will be obtained using orthogonal solvent systems.

Finding suitable solution-processable recombination, electron and hole accepting layer, that can be sequentially deposited without damaging the underlying layers, will be a major goal of the project.

We will employ a recently engineered acetonitrile/methylamine solvent system to deposit a narrow band gap rear-cell with improved stability, by employing more stable ionic perovskite compositions and introducing effective reducing agents.
