Organic solar cells (OSCs) are emerging as one of the more versatile photovoltaic technologies inthe third-generation solar cell technology domain, owing to their unique characteristics of flexibility, ultralightweight form factors, low-temperature processing, and compatibility with high-throughput printing techniques. Advancements in donor–acceptor materials have pushed OSC efficiency and stability to levels suitable for a widening set of applications, from indoor photovoltaics and IoT power systems to portable and building-integrated energy photovoltaics. Innovations in device architecture, interfacial engineering, and encapsulation are addressing long-standing barriers related to short operational lifetime and degradation, enabling OSCs to progress steadily toward commercial viability. This research study includes an overview of the scope, growth drivers, and constraints shaping the adoption of OSCs; a technical introduction to emerging OSC technologies and designs along with the comparative analysis on key performance parameters; an analysis of the innovation ecosystem, covering key commercial players, research groups, and innovators in the OSC domain; and intellectual property trends and strategic growth opportunities that stakeholders can target to drive the next wave of growth in the OSC domain.
