US Patent:

45422559, Sep 17, 1985

Filed:

Jan 3, 1984

Appl. No.:

6/567601

Inventors:

David P. Tanner - Thousand Oaks CA
Don L. Morel - Agoura Hills CA
Robert R. Gay - Granada Hills CA

Assignee:

Atlantic Richfield Company - Los Angeles CA

International Classification:

H01L 3106

US Classification:

136249

Abstract:

An improved transparent conductor structure for thin film solar cells comprising a plurality of metallic strip conductors deposited on a transparent conductor and aligned substantially with the principal direction of current flow. The strip conductors preferably originate at an edge of the transparent conductor to which an adjacent cell back conductor is connected and are preferably interconnected along that edge by an additional strip conductor deposited in the same process step.

International Classification:

G01J 300

US Classification:

356300

Abstract:

The present invention relates to a system and methods for measuring the haze of a thin film, such as a transparent conductive film, deposited on a substrate by either the reflectance of light by the external surface or the scattering of light by the internal grain surfaces of the thin film. More particularly, the haze measuring system is operated fully under computer control. The control program guides an operator through a calibration procedure, then calculates the haze of a thin film by comparing the reflectance minima at a wavelength of 500 nm or the ratio of the reflectance amplitude at 500 nm to 800 nm to calibration standards.

Assignee:

Atlantic Richfield Company - Los Angeles CA

International Classification:

H01L 3106
H01L 3118

US Classification:

136249

Abstract:

A photovoltaic device has a continuous thin film with a plurality of spaced photovoltaic regions thereon and front and back electrode portions substantially coextensive with each of the photovoltaic regions. Electrical connection between the regions is provided directly through the film itself, from each back electrode portion to the front electrode portion of an adjacent region. Thus, at least two of the photovoltaic regions are connected in series to increase the output voltage of the device.

US Classification:

Abstract:

Cells of a thin film solar module having opposed upper and lower electrodes are connected in series by a plurality of discrete conductive regions extending between each upper electrode and the lower electrode of an adjoining cell. In a preferred embodiment, the opposite electrodes of adjoining cells overlap one another and one of the electrodes is a transparent conductive pad with a thickened metal-containing portion to aid in interconnection. In another embodiment, the conductive regions are formed by applying laser pulses to spaced locations along the areas of electrode overlap, after which a conductor may be deposited into cavities formed by the laser pulses.
