Abstract
Photovoltaic research explores and expands solar cell development, with efforts focusing on improved performance output, applying more cost-efficient and environmentally friendly materials, and establishing longer-lasting durability. Moreover, photovoltaic research also investigates solar cell degradation and understanding degradation mechanisms to develop solutions for better preserving cell performance. Perovskite solar cells possess strong technological potential due to their industrially feasible processing procedures and competitive performance output. However, perovskite solar cells face difficulties with industrial and commercial scalability alongside intrinsic instability during operation. This work addresses the processing behind perovskite solar cell development, encompassing procedures that develop a cell's architecture. Furthermore, characterization techniques involve efficiency, fill factor, short-circuit current density, and open-circuit voltage parameter outputs, capacitance over area readings, and how the absorption mechanism collects charges from incoming photons. Standardized performance analysis with perovskite solar cells will then pivot into degradational experimentation and analysis. As this work reviews degrading solar cell performance, degradation mechanisms and their effects will be discussed and further explored. Conclusions will address specific degradation phenomena occurring within the cells as supported by characterization analysis. Furthermore, future work targets additional plausible characterizations for pursuing degradation analysis and discusses refining experimental procedures for a more critical approach in analyzing solar cell stability.
