SOLAR CELL WITH AN ELECTRICALLY INSULATING LAYER UNDER THE BUSBAR

摘要

A solar cell includes a photovoltaic energy source, a frontside array of metallic gridlines deposited upon a front face of the photovoltaic energy source, and a busbar structure in electrical continuity with the frontside array of metallic gridlines. The busbar structure has an electrical insulator layer overlying and contacting the front face of the photovoltaic energy source, and a metallic busbar layer overlying and contracting the electrical insulator layer. The metallic busbar layer is in electrical continuity with the frontside array of metallic gridlines. The solar cell is preferably a concentrator solar cell.
