For 30 years, Sharp scientists have researched, invented and improved solar cells made of very thin layers of semiconductors. In 2005, our first manufacturing line for fully-tested and market-ready thin film was up and running. These modules are made with less than 1% of the silicon used in the crystalline lines and are manufactured using automated equipment in fewer steps. This means a step-function change in cost per watt and a lower effective cost per kilowatt hours for large-scale applications. With thin film, we address the emerging market for utility-scale solar power, especially for very large scale ground-based installations in hot climates where abundant open space is available. For every kW of rated power, thin film delivers more kilowatt hours-up to 10%-than its crystalline-silicon cousin, due to substantially greater resistance to losses caused by typical mid-day operating temperature.
