With the planned electrification of everyday life, solar cells represent one of the more promising alternative energy sources. Significant investments are being made in the construction of solar power plants as well as the development of solar cells. Researchers strive to find materials and manufacturing methods that are cost-effective. One of the promising materials is perovskite.
This has led to accelerated studies on the functioning of perovskite solar cells, with a strong focus on its stability. However, shading of the modules, which induces reverse voltage on individual cells, is one of the important factors affecting the performance of solar cells.
This thesis presents the process of fabrication of perovskite solar cells, starting from a glass substrate. Through substrate cleaning, solution deposition, and contact application methods, a functioning perovskite solar cell is obtained. Devices such as ultrasonic and ultraviolet ozone cleaners, spin coaters and evaporators are employed in this process. For the purpose of performance analysis, several series of solar cells were fabricated.
In the second part of the thesis, the focus is on analyzing the characteristic properties of the manufactured solar cells and investigating the impact of reverse voltage on their performance. This includes measuring breakdown voltages and observing variations among the cells due to the fabrication process. It is also discovered that the majority of the fabricated perovskite solar cells can withstand temporary reverse voltage conditions, while some undergo irreversible damage.
