    Abstract: Fabrication methods for making back contact back junction solar cells. A base dopant source, a field emitter dopant source, and an emitter dopant source are deposited on the back surface of a solar cell substrate. The solar cell substrate is annealed forming emitter contact regions corresponding to the emitter dopant source, field emitter regions corresponding to the field emitter dopant, and base contact regions corresponding to the base dopant source. The base dopant source, field emitter dopant source, and the emitter dopant source are etched. A backside passivation layer is deposited on the back surface of the solar cell. Contacts are opened to the emitter contact regions and the base contact regions through the backside passivation layer. Patterned base metallization and patterned emitter metallization is formed on the back surface of the solar cell with electrical interconnections to the base contact regions and the emitter contact regions.

    Abstract: Passivated contact structures and fabrication methods for back contact back junction solar cells are provided. According to one example embodiment, a back contact back junction photovoltaic solar cell is described that has a semiconductor light absorbing layer having a front side and a backside having base regions and emitter regions. A passivating dielectric insulating layer is on the base and emitter regions. A first electrically conductive contact contacts the passivating dielectric insulating layer together having a work function suitable for selective collection of electrons that closely matches a conduction band of the light absorbing layer. A second electrically conductive contact contacts the passivating dielectric insulating layer together having a work function suitable for selective collection of electrons that closely matches a valence band of the light absorbing layer.

    Abstract: The present disclosure presents a three-dimensional thin film solar cell (3-D TFSC) substrate having enhanced mechanical strength, light trapping, and metal modulation coverage properties. The substrate includes a plurality of unit cells, which may or may not be different. Unit cells are defined as a small self-contained geometrical pattern which may be repeated. Each unit cell structure includes a wall enclosing a trench. Further, the unit cell includes an aperture having an aperture diameter. For the purposes of the present disclosure, the dimensions of interest include wall thickness, wall height, and aperture diameter. A pre-determined variation in these dimensions among unit cells across the substrate produces specific advantages.
