Metallization—the process of forming metal contacts on solar cell surfaces to extract photo-generated current—is one of the most costly and technically demanding steps in crystalline silicon (c-Si) solar cell fabrication. Beyond its role in current collection, metallization impacts both the electrical and optical performance of solar cells: contacts contribute to shading and series resistance, and can also reduce voltage through charge carrier recombination at the metal/silicon interface. Overcoming these challenges is critical to further increasing solar cell conversion efficiency while simultaneously reducing manufacturing costs.
This book presents the state of the art in metallization technologies for crystalline silicon solar cells, covering both industrial-scale production and advanced research and development. It provides a systematic comparison of different metallization approaches, along with detailed descriptions of ongoing R&D efforts into the most promising technologies.
