Abstract
Solar cell fabrication using laser patterning of ion-implanted etch-resistant layers, and the resulting solar cells, are described. In an example, a back contact solar cell includes a maximum concentration of the approximately Gaussian distribution of P-type dopants approximately in the center of each of segmented P-type emitter regions between first and second sides of each of the segmented P-type emitter regions.
