Advances in Solar Cell Technologies: A Comprehensive Review of Material Synthesis, Structural Properties, Efficiency and Diverse Applications

Abstract

Solar cells represent one of the most promising renewable energy technologies for addressing global energy demands and climate change challenges. This paper provides a comprehensive review of photovoltaic technology, examining the fundamental principles underlying solar cell operation, various cell types and their efficiencies, key material properties, synthesis methods, and emerging applications. Current commercial silicon-based technologies achieve efficiencies of 20-26%, while emerging perovskite and multi-junction cells demonstrate potential for efficiencies exceeding 40%. Manufacturing techniques continue to evolve, with thin-film deposition and advanced processing methods reducing costs while improving performance. Future applications range from building-integrated photovoltaic to space-based solar power systems, positioning solar technology as a cornerstone of sustainable energy infrastructure.
