Patent number: 7897020Abstract: A method of manufacturing a solar cell includes providing a substrate, depositing a first electrode comprising an alkali-containing transition metal layer over the substrate, depositing at least one p-type semiconductor absorber layer over the first electrode, wherein the p-type semiconductor absorber layer includes a copper indium selenide (CIS) based alloy material, depositing an n-type semiconductor layer over the p-type semiconductor absorber layer, and depositing a second electrode over the n-type semiconductor layer. The step of depositing the alkali-containing transition metal layer includes sputtering from a first target comprising the transition metal and a second target comprising the alkali metal, where a composition of the first target is different from a composition of the second target.Type: GrantFiled: April 13, 2009Date of Patent: March 1, 2011Assignee: MiaSoleInventors: Neil M.

Publication number: 20030206688Abstract: An optical wavelength division multiplexer and de-multiplexer, for single or multi-mode fiber optic communications, includes a base plate that serves as a miniature optical bench, and a series of free-space optical components including collimators, narrow band filters, and highly efficient reflective mirrors mounted to the base plate. The free-space light beam is reflected off of each narrow band filter in a serial manner, whereby narrow bands of light matching the filter are focused into output optical fibers. Each component may be individually adjusted by computer-controlled robotics to achieve accurate optical alignment and provide compensation among the components. The angle of incidence of the light signals at the filters is kept below 10 degrees for DWDM applications, and below about 14 degrees for CWDM applications to minimize polarization dispersion loss. A simplified sealing system provides robust protection from environmental hazards, while further reducing costs and improving manufacturing yields.Type: ApplicationFiled: May 3, 2002Publication date: November 6, 2003Inventors: Dennis R. Hollars, Paul T. Alexander, Rodrick G. Cross, Randy Dorn, Kenneth Nelson, Robert B. Zubeck

Patent number: 6231732Abstract: A cylindrical carriage sputtering system for disk, wafer, and flat panel substrates (20) comprising a cylindrical shaped vacuum sealed passageway formed by two concentric inner (11) and outer hollow cylinders (12), along with a top and a bottom sealing flange (13, 14). A central hollow cylinder (15), disposed between the inner (11) and outer cylinder (12), includes substrate-carrying openings and serves as a cylindrical carriage which substantially fills the sealed passageway and is rotatable in predetermined steps. Novel substrate processing devices (16) for deposition, heating, and cooling are attached around the circumference of the inner and outer cylindrical walls. Vacuum pumps are located between substrate processing devices (16). The openings in the cylindrical carriage are each fitted with thermally isolated substrate holders (19) for supporting a multiplicity of substrates (20).Type: GrantFiled: September 2, 1999Date of Patent: May 15, 2001Assignee: SciVacInventors: Dennis R. Hollars, Robert B. Zubeck

Patent number: 5753092Abstract: A sputtering system comprising three concentric cylinders. The inner and outer cylinders, along with top and bottom sealing flanges, form an annular chamber with cylindrical walls. A central cylinder, disposed between the inner and outer cylinders, includes substrate-carrying openings and serves as a cylindrical carriage which substantially fills the annular chamber passageway and is rotatable in predetermined steps relative to the chamber. Substrate processing devices for deposition, etching, heating, and cooling arc attached around the circumference of the inner and/or outer cylinders. Vacuum pumps are located between substrate processing devices. The openings in the cylindrical carriage are each fitted with a substrate holder for supporting a multiplicity of substrates. Entrance and exit vacuum load-locks are provided for transferring substrates into and out of the system. The system is designed for substrate processing temperatures of 1000.degree. C. and above.Type: GrantFiled: August 26, 1996Date of Patent: May 19, 1998Assignee: Velocidata, Inc.Inventors: Dennis R. Hollars, Robert B. Zubeck
