Abstract: An example of an apparatus to generate electricity from light with photovoltaic cells is provided. The apparatus includes a plurality of photovoltaic cells. The plurality of photovoltaic cells is to form a module. Furthermore, the apparatus includes an electro-conductive backsheet to connect the plurality of photovoltaic cells. The electro-conductive backsheet is to collect current from the plurality of photovoltaic cells. Each photovoltaic cell of the plurality of photovoltaic cells is formed on a silicon wafer by cutting along a {100} plane to provide a substantially square wafer and cleaving the substantially square wafer along a preferred cleavage plane.

Abstract: The present invention relates a photovoltaic module comprising 126, 138 or 150 back-contact half-cells. In an embodiment, the half-cells are divided into 3 groups of each 2 parallel strings with each string containing ? of the total number of half-cells. The module comprises an additional row of 6 back-contact half-cells, relative to known half-cell modules.

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.
