Abstract

In recent years, perovskite solar cells (PSCs) have experienced rapid and unprecedented development and have become candidates for solar cells. Among perovskite solar cells, metal halide perovskite solar cells are known as one of the recent innovations in the field of renewable energy. These cells have received much attention due to their high efficiency. One of the main advantages of these cells is the ease of production and the possibility of optimizing their electronic properties. Also, their ability to absorb light at different wavelengths can lead to an increase in energy conversion efficiency. However, there are still challenges such as sustainability and long-term life, which require further research. Since the efficiency of perovskite metal halide solar cells can be significantly increased by changing the band gap and improving the structure, in this article, by changing the dimensions of perovskite metal halide, which all have lead and iodine in their structure, the band gap is improved. The use of Quantum Espresso software package has been calculated and the appropriate band gap interval has been investigated to increase efficiency for use in solar cells.
