Hybrid organic-inorganic lead halide perovskites (LHPs) have emerged as promising light absorber materials in next generation of thin film photovoltaic technology due to their simple solution-processed technique and high-power conversion efficiency (PCE) exceeding 25%. The outstanding performance of perovskite solar cells (PSCs) is ascribed to the excellent physicochemical properties of these ambipolar semiconductors, however, their instability under high thermal, moisture and operational conditions are issues that needs to be addressed. In this context, a great deal of current interest in the perovskite community has been focused on the understanding of chemical instability of LHPs and developing strategies for making more robust PSCs.

The overall goal of the project is to develop advantageous strategies in enhancing the stability of PSCs. To realize the aims, the compositional and additive engineering will be applied to develop the fabrication of high quality perovskite thin films with improved stability. In addition to engineering of the perovskite layer, the formation of appropriate charge-selective contacts, electron transport layers (ETLs), with suitable energy-level alignment for perovskite plays a vital role in PSCs performance and stability. In this project this issue will be addressed by surface engineering of the ETL/perovskite interface with novel fullerene derivatives and hybrid 3D porous metal organic-framework (MOF) materials, which would promote the development of stable and efficient PSCs. Integral part of the proposal will be the fully physicochemical characterization and stability analysis in complex conditions of temperature and humidity of the resulted solar cells.

The successful candidate will investigate issues related to the fabrication of perovskite solar cells and understand the phenomena and processes that determine their efficiency and stability under working conditions.
