Silicon is the dominant semiconductor material in use for terrestrial photovoltaic cells. The critical issues in cell design, materials specification and cell processing are reviewed. Specific attention is given to light trapping, minority carrier lifetime control and novel microstructures for enhancing photon absorption. Relevant topics in generic defect control are discussed with particular emphasis on compound semiconductor materials.
