Abstract

In light of the urgent need to adopt green, sustainable energy sources, intensive efforts have been devoted to develop various types of solar cells with the aim of realising efficient, stable, and low-cost photovoltaic (PV) devices. Amongst the next-generation PV technologies, organic–inorganic lead halide perovskite solar cells (PSCs) have attracted enormous attention due to their high efficiency and ease of fabrication. Although this class of PV devices has undergone unprecedented rapid development in recent years, they still suffer from some drawbacks such as poor long-term stability, toxicity of lead, hysteresis, complicated synthesis procedures, and high cost of the materials involved in their fabrication process. In this talk, I present our latest research on addressing some of the aforementioned obstacles through different approaches including the formation of multidimensional perovskites and the incorporation of two-dimensional (2D) layered structures. The potential of using other emerging solar cells, in particular antimony trisulfide-based solar cells, will also be discussed.
