Governments worldwide are committed to tripling global renewable energy capacity by 2030 to limit global temperature rise to 1.5 °C above pre-industrial levels. Solar energy, powered by silicon solar cells, plays a critical role in this transition with silicon (Si)-wafer-based technology holding 97% of the market share. Achieving this ambitious goal for renewable energy generation requires significant advancements in efficiency and cost-effective production. The efficiency of silicon solar cells has evolved dramatically, from the 6% of the first cell developed at Bell Labs in 1954 to the record-breaking 27.3% achieved in a back-contacted architecture (HBC) by LONGi in 2024. This chapter describes the development of silicon solar cell architectures, detailing the variations, design improvements, and technological breakthroughs that have shaped the industry. The small changes in cell architecture, passivation, etc., were found to significantly impact the efficiency and production scalability. Beyond lab-scale innovations, how these technologies transition to mass production is discussed. Each architecture, including Aluminium Back Surface Field (Al-BSF), Passivated Emitter and Rear Cell (PERC), Silicon Heterojunction (SHJ), Interdigitated Back Contact (IBC), Dopant-Free Asymmetric Heterocontact Solar Cells (DASH), Carrier-Selective Solar Cells (CSCs), Tunnel Oxide Passivated Contact (TOPCon), and Polycrystalline Oxide Layer (POLO), is explored in-depth, with a focus on how design adjustments ensure industrial feasibility. The challenges and solutions to making these cells viable for large-scale deployment are discussed, highlighting the processes required, while maintaining high efficiency. The chapter gives a comprehensive insight into the enhancement in cell performance with the developments in cell architectures and in facilitating their integration into the global renewable energy landscape.
