    摘要： A dielectric film stack of a solar cell is ablated using a laser. The dielectric film stack includes a layer that is absorptive in a wavelength of operation of the laser source. The laser source, which fires laser pulses at a pulse repetition rate, is configured to ablate the film stack to expose an underlying layer of material. The laser source may be configured to fire a burst of two laser pulses or a single temporally asymmetric laser pulse within a single pulse repetition to achieve complete ablation in a single step.

    摘要： 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.

    摘要： Solar cells having a plurality of sub-cells coupled by metallization structures, and singulation approaches to forming solar cells having a plurality of sub-cells coupled by metallization structures, are described. In an example, a solar cell, includes a plurality of sub-cells, each of the sub-cells having a singulated and physically separated semiconductor substrate portion. Adjacent ones of the singulated and physically separated semiconductor substrate portions have a groove there between. The solar cell also includes a monolithic metallization structure. A portion of the monolithic metallization structure couples ones of the plurality of sub-cells. The groove between adjacent ones of the singulated and physically separated semiconductor substrate portions exposes a portion of the monolithic metallization structure.
