Lead-Free Perovskite Solar Cells and High-Throughput Methods for Accelerated Materials Discovery

Abstract

As the demand for sustainable energy technologies grows, the search for efficient, low-cost, and non-toxic solar cells becomes increasingly urgent. Perovskite solar cells have emerged as a leading candidate due to their excellent optoelectronic properties and ease of fabrication. Among them, lead-free tin-based perovskites offer a more environmentally friendly alternative, but challenges such as instability, self-doping, and short carrier lifetimes have limited their performance. In this talk, Dr. Musiienko will present recent progress in overcoming these limitations through innovative materials engineering and high-throughput experimentation. His work focuses on understanding and improving tin perovskite interfaces using novel contact materials like self-assembled monolayers (SAMs), which enable enhanced charge extraction and long-term stability. A key aspect of his approach is the development of advanced, contactless characterization methods—including surface photovoltage (SPV) mapping and constant light-induced magneto-transport (CLIMAT)—which allow for rapid screening of electronic and interfacial properties without full device fabrication. Combined with automated synthesis platforms, these methods accelerate materials discovery and optimization by more than an order of magnitude. Dr. Musiienko will share insights from recent breakthroughs that have led to record-performing lead-free perovskite devices and discuss how these strategies are paving the way toward stable, high-efficiency tandem solar cells with target efficiencies beyond 35%.

 

Das Kolloquium wird "hybrid" durchgeführt, kann also sowohl im Hörsaal als auch über zoom verfolgt werden.
