Photovoltaic cells with selectively patterned transparent conductive coatings, and associated methods

摘要

A photovoltaic cell comprising a selectively patterned, transparent, conductive coating (TCC) on a sunward surface. The selectively patterned TCC is contiguous with at least some highly conductive gridlines on the sunward surface. A portion of the sunward surface of the semiconductor wafer is not covered by either the gridlines or the TCC. Also disclosed are methods of manufacturing a photovoltaic cell comprising a selectively patterned, transparent, conductive coating (TCC) on a sunward surface. The methods include the step of modeling the optical and electrical properties of the semiconductor, the gridlines, and the TCC to determine a pattern for the TCC that results in a low relative power loss for the photovoltaic cell.
