Highly densified pv module

A photovoltaic module, comprising:

• a plurality of photovoltaic cells arranged in rows and columns, wherein the rows include a first row, a last row, and one or more intermediate rows between the first and last TOWS;
• a continuous backsheet positioned behind the plurality of photovoltaic cells, wherein the continuous backsheet includes a ground plane for the plurality of photovoltaic cells and the continuous backsheet is electrically coupled between the first row of the plurality of photovoltaic cells and the last row of the plurality of photovoltaic cells;
• a circuit card mechanically coupled to a back of the photovoltaic module, wherein the circuit card includes a first connector with a first polarity and a second connector with a second polarity opposite the first polarity;
• and
• a buried first polarity contact positioned behind the plurality of photovoltaic cells, wherein the buried first polarity contact is electrically coupled to a back of each photovoltaic cell in one of the rows of the plurality of photovoltaic cells and wherein the buried first polarity contact extends through a slot formed in the continuous backsheet to electrical contact with the first connector of the circuit card.
