Problems solved by technology

[0009] However, this system cannot efficiently harvest sunlight while providing easily visible discernible features because at least some efficiency is sacrificed by providing spacing between solar cells to allow features on the back of the panel to be visible.

Embodiment Construction

[0066] The present invention will now be described more fully hereinafter with reference to the accompanying drawings, in which embodiments of the invention are shown. However, this invention should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. In the drawings, the thickness of layers and regions are exaggerated for clarity. Like reference numerals refer to like elements throughout.

[0067] It will be understood that when an element such as a layer, region or substrate is referred to as being "on" or "extending onto" another element, it can be directly on or directly extending onto the other element. on another element, or intermediate elements may also be present. In contrast, when an element is referred to as being "directly on" or "directly extending onto" another element, there are...

Abstract

A concentrated photovoltaic and display apparatus includes a backplane substrate, a plurality of photovoltaic elements distributed over the backplane substrate, a plurality of display elements distributed over the backplane substrate between the photovoltaic elements, and an optical element positioned over the backplane substrate, the photovoltaic elements, and the display elements. The optical element is configured to concentrate incident light propagating in a direction substantially parallel to an optical axis thereof onto the photovoltaic elements. The optical element is further configured to direct light reflected or emitted from the display elements in a direction that is not substantially parallel to the optical axis of the optical element. Related fabrication methods and arrays including the apparatus are also discussed.

Description

[0001] priority claim [0002] This application claims priority to US Provisional Patent Application No. 61 / 352,028, filed June 7, 2010, in the US Patent and Trademark Office, entitled "Photovoltaic Device with Off-Axis Image Display," the disclosure of which is incorporated herein by reference. technical field [0003] The present invention relates to photovoltaic devices, and more particularly to concentrating photovoltaic devices incorporating integrated display elements. Background technique [0004] Large substrates with electroactive components arranged or dispersed over the confines of the substrate can be used in a variety of electronic systems, for example, imaging devices such as flat-panel liquid crystal or OLED display devices, and / or digital in radiographic plates. Large substrates with electroactive components are also found in flat-panel solar cells. [0005] Concentrated photovoltaic (CPV) solar cell systems use lenses or mirrors to focus a relatively large...
