Abstract
The invention provides a bifacial photovoltaic cell comprising: a semiconductor substrate, the substrate comprising an n+ layer on a first surface, and a p+ layer on a second surface. The n+ layer comprises an n-dopant and the p+ layer comprises a p-dopant. The cell further comprises a passivating and/or antireflective coating on the doped first and second surfaces. The cell is characterized in that the second surface of the semiconductor substrate has an area substantially devoid of the p-dopant on an edge of the second surface having a width in the range of 0.1-0.5 mm; wherein the area is formed by etching the semiconductor substrate.
