<p>Perovskite solar cells (PSCs) are one of the photovoltaic technologies that has progressed rapidly. In the development of fabrication techniques for these devices, blade-coating and spin-coating techniques have emerged as significant industrial processes with great potential for converting renewable energy. In this review article, a comprehensive study of these techniques has been conducted to evaluate their advancements and commercial viability. The blade-coating technique has shown development in power conversion efficiency from 2.06% to 25.31%, whereas the spin-coating technique has shown improvement from 4.2% to 26.08%. This improvement in power conversion efficiency (PCE) highly depends on factors such as the achievement of the desired film homogeneity and the rate of crystallization. For the consistent fabrication of films with better quality and longer lifetime, technologies such as Lewis acid–base adducts, solvent engineering, additive engineering, and anti-solvent engineering were examined. An interdisciplinary and diversified approach needs to be adopted in the development of perovskite solar cells. We have discussed the strengths and weaknesses of individual techniques with respect to scalability and adaptability. This review article will provide readers with insight into the challenges occurring in the development of perovskite solar cells, such as environmental sensitivity, short processing windows, scalability, and many others.</p>
