Abstract

A bifacial photovoltaic module with at least one bifacial solar cell is provided. The at least one bifacial solar cell includes a substrate with a front-side and a rear-side. The front-side is the light incident side and the rear-side has rear-side contact structure. The rear-side contact structure includes a plurality of electrically conductive contact fingers, which have a first metal, a plurality of solder pads electrically connected to the contact fingers. The solder pads have a top. The solder pads have a second metal, which is different from the first metal. The rear-side contact structure further includes several cell connectors electrically connected to the solder pads. The top of the solder pads is free from the contact fingers in an area along one direction. The cell connectors are disposed planar on or above this area.
