    摘要: Forming a porous layer on a silicon substrate. Forming the porous layer can include placing a first silicon substrate in a solution, where a first electrode is within a threshold distance to an edge of the silicon substrate. It can further include conducting a first current through the silicon substrate, where the first electrode can be positioned relative to the edge allowing for substantially uniform porosification along the edge of the first silicon substrate.

    摘要: A method for plating metal to a solar cell is disclosed. The method includes plating a metal layer only on the surface of solar cell without plating metal along the solar cell edges by conducting a first current in a first direction in an electroplating bath, ejecting metal from the metal layer by conducting a second current in a second direction and plating additional metal to the metal layer by conducting a third current in the first direction. The first, second and third current can be alternated. Subsequent to an electroplating process, an ultrasonic cleaning process is performed on the solar cell to remove any excess plated metal along the surface and edges of the solar cell.

    摘要: A solar cell and a solar laminate are described. The solar cell can have a front side which faces the sun during normal operation and a back side opposite front side. The solar cell can include conductive contacts having substantially reflective outer regions disposed on the back side of the solar cell. The solar laminate can include a first encapsulant, the first encapsulant disposed on the back side of the solar cell and a second encapsulant. The solar laminate can include the solar cell laminated between the first and second encapsulant. The substantially reflective outer regions of the conductive contacts and the first encapsulant can be configured to scatter and/or diffuse light at the back side of the solar laminate for substantial light collection at the back side of the solar cell. Methods of fabricating the solar cell are also described herein.
