Perovskite solar cells (6 units)

Project description:

The increasing energy consumption of the modern society drives an urgent demand for clean and renewable energy generation exceeding fossil fuels. Amongst a spectrum of alternative energy sources including wind, hydro, solar, and nuclear powers, photovoltaics (PVs) have been considered as one top technology candidate, because they could potentially capture solar energy of about ten thousand exajoules annually into electricity that will be conveniently distributed for everyday activities of human beings. While silicon (Si) is proven able to serve in PV panels efficiently and they are robust in the real-world applications, the energy payback time of Si PVs can be more than 2 years, and their production involves high-temperature synthesis and hazardous purification process, inevitably imposing adverse effects on the environment. In this regard, the field of solar energy is intensively searching for new-generation PV materials that not only exhibit favorable optoelectronic properties for high device performance but also are easy and cheap for industrial fabrication. One most significant step that meets this demand is the intriguing discovery of halide perovskites (HPs) based PV materials, drawing phenomenal attention across the academia, industry, and governmental sectors. The first perovskite solar cell (PSC) was reported by Miyasaka and coworkers with only 3.8 %, but the following decade have witnessed an unprecedented growth and expanding of this emerging research area, leading to a swift evolution in device efficiency to 25.5 %. This progress is largely driven the innovation and optimization of device fabrication processes, where basic materials and device physics play a significant role. 

This FYP project comprises two components: (1) acquire basic principles about the perovskite materials and perovskite solar cells, and (2) application of perovskite solar cells in the real world.
