  • Systems and methods for handling wafers
    Patent number: 9184079
    Abstract: A system for handling wafers comprising: at least one unload station; at least one intermediate station designed to hold the wafers at an angle; a processing station; and a transfer device configured to move the wafers between the stations. The intermediate station may be configured to receive the wafers in a back-to-back arrangement. An apparatus for handling wafers comprising: on one side, a vacuum gripper configured to grip individual wafers; and, on the other side, a gravity gripper configured to support one or more wafers when positioned beneath the wafers and lifted. A method for handling wafers, comprising: unloading wafers; transferring the wafers to an intermediate station; transferring the wafers from the intermediate station to a processing station; treating the wafers; unloading the wafers from the processing station; and reloading the wafers in a carrier, wherein the wafers are unloaded, transferred and reloaded by a transfer device.
    Type: Grant

  • Method of fabricating an optical concentrator for a photovoltaic solar cell
    Patent number: 7312097
    Abstract: A method of fabricating a photovoltaic solar cell is provided. A plurality of generally spherical semiconductor elements are provided. Each of the semiconductor elements has a core and an outer surface surface forming a p-n junction. An anti-reflection coating is deposited on the outer surface of each of the semiconductor elements and each of the semiconductor elements is bonded into a perforated aluminum foil array thereby providing ohmic contact to a first side of the p-n junction. The anti-reflection coating is removed from a portion of each of the semiconductor elements and then the core is exposed, thereby allowing ohmic contact to be made to a second side of the p-n junction.
