  • Process for manufacturing a solar cell
    Patent number: 7071018
    Abstract: Process for incorporating a back surface field into a silicon solar cell by depositing a layer of aluminium on the rear surface of the cell, sintering the aluminium at a temperature between 700 and 1000° C., exposing the cell to an atmosphere of a compound of Group V element and diffusing at a temperature of between 950 and 1000°C. so as to dope exposed p-type silicon surfaces with the Group V element. The step of exposing the cell to an atmosphere of a compound of a Group V element is carried separately from the step of sintering the aluminium layer, and subsequent to the step of depositing a layer of aluminium on the rear surface of the cell.

  • Process for depositing metal contacts on a buried grid solar cell and solar cell obtained by the process
    Patent number: 6881671
    Abstract: A buried grid solar cell is manufactured by a process for metallising one or more metal contacts of a buried grid solar cell having a body of doped semiconductor material, wherein the electrical contact(s) is/are provided by conducting material being arranged in a pattern of one or more grooves into the semiconductor material by an electrolytic metal deposition process comprising a conventional electrolytic bath containing a special combination of per se known additives.
