Topic of Research Seminar: Perovskite solar cells; synthesis, applications and future outlook

Abstract: Perovskites have attracted the attention of researchers for more than a decade due to their high Power conversion efficiency (PCE). Perovskite-based materials have excellent chemical and physical properties, making them suitable for producing solar cells. Perovskites are prepared on a small scale through dual source vapour deposition, one-step solution deposition, two-step solution deposition, vapour-assisted solution deposition, and sequential deposition technique. Whereas on a large scale, industries use various methods for perovskite preparation, such as Inkjet printing, drop casting, blade coating, slot-dry coating and spray coating. Unfortunately, perovskite solar cells face many issues and challenges in commercialization as their stability is only in a few months and they also face J-V hysteresis. Research emphasizes film formation and interfacial engineering improvements to enhance device efficiency and stability. However, commercialization requires addressing degradation issues from environmental factors like moisture and UV light, prompting the need for standardized stability tests and conditions for optimal performance. This review is aimed at exploring the complexities of perovskite structure along with the fabrication techniques at large as well as the small scale.

Additionally, it critically analyzes the challenges and obstacles encountered in the commercialization of perovskites. Finally, the review provides insights into future strategies for achieving high efficiency in perovskite solar cells
