A new type of silicon photovoltaic cell designed for high concentration applications is presented. The device is called the point-contact-cell and shows potential for achieving energy conversion efficiencies in the neighborhood of 28 percent at the design operating point of 500X geometric concentration and 60/sup 0/C cell temperature. This cell has alternating n and p regions that form a polkadot array on the bottom surface. A two-layer metallization on the bottom provides contact. Initial experimental results have yielded a cell with 20-percent efficiency at a concentration of 88.
