    Abstract: A method for manufacturing high efficiency solar cells is disclosed. The method comprises providing a thin dielectric layer and a doped polysilicon layer on the back side of a silicon substrate. Subsequently, a high quality oxide layer and a wide band gap doped semiconductor layer can both be formed on the back and front sides of the silicon substrate. A metallization process to plate metal fingers onto the doped polysilicon layer through contact openings can then be performed. The plated metal fingers can form a first metal gridline. A second metal gridline can be formed by directly plating metal to an emitter region on the back side of the silicon substrate, eliminating the need for contact openings for the second metal gridline. Among the advantages, the method for manufacture provides decreased thermal processes, decreased etching steps, increased efficiency and a simplified procedure for the manufacture of high efficiency solar cells.

    Abstract: Contact holes of solar cells are formed by laser ablation to accommodate various solar cell designs. Throughput of the solar cell ablation process is improved by incorporating linear base diffusion regions with narrow width, for example as compared to an overlying metal contact. Throughput of the solar cell ablation process may also be improved by having contact holes to base diffusion regions that are perpendicular to contact holes to emitter diffusion regions. To allow for continuous laser scanning, a laser blocking layer may be located over an interlayer dielectric to prevent contact hole formation on certain regions, such as regions where a metal contact of one polarity may electrically shunt to a diffusion region of opposite polarity. In a hybrid design, a solar cell may have both linear and dotted base diffusion regions. An electro-optical modulator may be employed to allow for continuous laser scanning in dotted base diffusion designs.
