Title: Method and apparatus of fabricating a solar cell device

Abstract

Solar cell devices as well as method and apparatus for producing solar cell devices are disclosed. Aspects of the disclosure provide a solar cell device that includes a string of solar cells. The string of solar cells are conductively connected in series and arranged in a shingled manner with sides of adjacent solar cells being overlapped. A first metal ribbon segment is conductively bonded to a front surface of an end cell, the front surface being configured to face a light incoming direction to receive energy from a light source.
