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.

Abstract: A solar device includes a first string of first solar wafers, wherein a plurality of the first solar wafers each overlap with at least one vertically adjacent solar wafer from the first string. Additionally, the solar device includes a second string of second solar wafers, wherein a plurality of the second solar wafers each overlap with at least one vertically adjacent solar wafer from the second string, wherein a plurality of the first solar wafers overlap with one or more of the plurality of second solar wafers to electrically connect horizontally adjacent solar wafers in parallel.
