Abstract: An example of an apparatus to convert light energy to electrical energy is provided. The apparatus includes a semiconductor material to absorb energy from a photon. The energy is to be converted to a current. Furthermore, the apparatus includes a positive electrode disposed on a backside of the semiconductor material to collect the current from the backside. In addition, the apparatus includes a via to connect the backside of the semiconductor material electrically to a frontside of the semiconductor material. The apparatus also includes a plurality of fingers disposed on the frontside of the semiconductor material to collect the current from the frontside. The apparatus further includes a trunkline connected to the plurality of fingers to deliver the current to the via. The trunkline is to increase a cross-sectional area toward the via to reduce parasitic resistance.

Abstract: The present invention is applied to photo voltaic module enhanced light. In particular, the present invention relates to glass-glass and back contact photo photovoltaic modules with enhanced conversion efficiency in areas that are not usually active.
