    摘要: A method for fabricating a contact (240) for a solar cell (200). The method includes providing a solar cell substrate (210) with a surface that is covered or includes an antireflective coating (220). For example, the substrate (210) may be positioned adjacent or proximate to an outlet of an inkjet printer (712) or other deposition device. The method continues with forming a burn through layer (230) on the coating (220) by depositing a metal oxide precursor (e.g., using an inkjet or other non-contact printing method to print or apply a volume of liquid or solution containing the precursor). The method includes forming a contact layer (240) comprising silver over or on the burn through layer (230), and then annealing is performed to electrically connect the contact layer (240) to the surface of the solar cell substrate (210) through a portion of the burn through layer (230) and the coating (220).

    摘要: A method (200) for depositing an aluminum film or contact (124). The method includes providing (230) a substrate (120) with a surface for receiving the aluminum film (124). The substrate (120) is heated (240) to a printing temperature such as over 150° C., and the method (200) includes depositing (250) a volume of ink upon a surface of the substrate (120). The ink (136) includes an organometallic aluminum complex or precursor, and the substrate surface temperature is selected or high enough to decompose the organometallic aluminum complex or precursor to provide aluminum of the film (124) and a gaseous byproduct. The depositing or printing (250) of the ink may be performed within an inert or substantially oxygen-free atmosphere (144). The ink (136) may be a solution of the organometallic aluminum complex and a solvent. The aluminum complex or precursor may include an amine compound and alane.

    摘要: A method of synthesizing multilayer heterostructures including an inorganic oxide layer residing on a solid substrate is described. Exemplary embodiments include producing an inorganic oxide layer on a solid substrate by a liquid coating process under relatively mild conditions. The relatively mild conditions include temperatures below 225° C. and pressures above 9.4 mb. In an exemplary embodiment, a solution of diethyl aluminum ethoxide in anhydrous diglyme is applied to a flexible solid substrate by slot-die coating at ambient atmospheric pressure, and the diglyme removed by evaporation. An AlOx layer is formed by subjecting material remaining on the solid substrate to a relatively mild oven temperature of approximately 150° C. The resulting AlOx layer exhibits relatively high light transmittance and relatively low vapor transmission rates for water. An exemplary embodiment of a flexible solid substrate is polyethylene napthalate (PEN). The PEN is not substantially adversely affected by exposure to 150° C.
