Appl. No.:

13/893494

Inventors:

- Tempe AZ, US
Robert Andrew Garber - Denver CO, US
Douglas Garth Jensen - Lakewood CO, US

Assignee:

First Solar, Inc. - Tempe AZ

International Classification:

H01L 31/0216
H01L 31/18
H01L 31/042

US Classification:

136246, 136256, 438 72

Abstract:

Thin film photovoltaic devices are provided that include a transparent substrate defining an inner surface and an outer surface; a thin film stack on the inner surface of the transparent substrate; an encapsulation substrate on the thin film stack; and a color reflection film on the outer surface of the transparent substrate. The thin film stack has a photovoltaic heterojunction (e.g., formed from a n-type window thin film layer and an absorber thin film layer). Generally, the color reflection film comprises a colorant, such as a refractive material (e.g., a nitride material, an oxide material, or mixtures thereof). Methods are also provided for forming such a photovoltaic device, and for forming an array of photovoltaic devices to define an image.

Abstract:

An apparatus and a method for detecting defects within a photovoltaic module are provided. To detect defects within the photovoltaic module, light from a light source is directed towards the photovoltaic module. The light generates a voltage within each solar cell of the photovoltaic module. The generated voltages are measured and compared in order to detect defects within the solar cells of the photovoltaic module.
