Abstract
An improved solar energy device has a body of semiconductor material of a first conductivity type with a region of a second conductivity type formed in the body and extending to its surface. A current collection metallization pattern is disposed on the second conductivity type region, with at least three distinct and identifiable current accumulation points connected to the metallization pattern adjacent to the periphery of the second conductivity type region. External electrical connection is made to extract available electrical power from the device at the current accumulation points. The periphery of the device is free of other electrically equivalent external electrical connection areas. These features allow a substantial increase in device efficiency.
