ABSTRACT:
Interdigitated back contact (IBC) solar cells are produced by depositing spaced-apart parallel pads of a first dopant bearing material (e.g., boron) on a substrate, heating the substrate to both diffuse the first dopant into corresponding first (e.g., p+) diffusion regions and to form diffusion barriers (e.g., borosilicate glass) over the first diffusion regions, and then disposing the substrate in an atmosphere containing a second dopant (e.g., phosphorus) such that the second dopant diffuses through exposed surface areas of the substrate to form second (e.g., n+) diffusion regions between the first (p+) diffusion regions (the diffusion barriers prevent the second dopant from diffusion into the first (p+) diffusion regions). The substrate material along each interface between adjacent first (p+) and second (n+) diffusion regions is then removed (e.g., using laser ablation) such that elongated grooves, which extend deeper into the substrate than the diffused dopant, are formed between adjacent diffusion regions.
