Perovskite Solar Cells: An Overview

In the past few years, perovskite solar cells have gained tremendous attention as promising alternatives to traditional silicon-based solar cells. Perovskite solar cells, or PSCs, are a family of solar cells made from metal halide perovskites, a type of mineral with a specific atomic structure. The properties of this material make it particularly advantageous for use in solar cells: it has excellent light absorption, chemical stability, and carrier mobility.

This review paper provides a comprehensive overview of perovskite solar cells, their fabrication, performance, and applications. First, an overview of the different types of PSCs and their materials is presented, including their chemical composition and properties. Then, an in-depth analysis of the fabrication process is conducted, describing the thin-film deposition techniques used to create PSCs and their associated layers. Finally, a discussion of the performance of PSCs as compared to other traditional solar cells is provided, along with some potential applications of PSCs in the future.

Creating PSCs requires a sequence of thin-film deposition techniques that are used to assemble the different layers of the cell. The first step is to deposit a thin layer of perovskite material onto a substrate, such as a glass or plastic sheet. This layer is then covered with an electron-selective layer, and followed by a hole-selective layer. Next, an interfacial layer is deposited, which provides structural support as well as electrical contacts. Finally, an electron-collecting layer is placed on top, completing the formation of the PSC.

The performance of PSCs depends on the relative thicknesses and composition of the different layers. Proper design is essential to maximize the efficiency and stability of the cell. Recent studies have indicated that PSCs can achieve efficiencies comparable to that of traditional silicon solar cells.

In addition, PSCs can be used for more than just solar cells: their perovskite material can also be used for light-sensitive devices and sensors, as well as for other types of renewable energy production.

To conclude, this paper has provided an overview of the properties and fabrication of perovskite solar cells. The performance of these cells has been shown to be on par with that of other traditional solar cells, and the applications of PSCs are versatile and wide-ranging. As more research is conducted in this field, the potential of PSCs to revolutionize the solar energy industry will continue to become more evident.
