Problems solved by technology

[0006] The methods described above cause the display to suffer from (1) reduced performance (e.g., low brightness, low resolution, etc.) due to light from the display being absorbed or blocked by the non-transparent PV (photovoltaic) material, or (2) ) has only a small photovoltaic material surface area, which is proportional to the total energy produced for a given cell type

Embodiment Construction

[0033] It will be appreciated that the drawings and descriptions of embodiments of wavelength selective photovoltaic (WPV) devices, elements, or components have been simplified to show elements that are relevant for clear understanding, while eliminating, for the sake of clarity, many other components are found in these electronic devices and packages. Those of ordinary skill in the art will recognize that other elements and / or steps are desirable and / or necessary in implementing a WPV device, element or component. However, since these elements and steps are well known in the art, and since they do not facilitate a better understanding of WPV devices, elements or components, a discussion of these elements and steps is not provided here.

[0034] The non-limiting embodiments described herein relate to WPV devices, elements or components. The embodiments and variations described herein and / or shown in the drawings are presented by way of example only, and do not limit the scope...

Abstract

Described herein is an apparatus and method used to provide power or photovoltaic functionality to a display or device containing a display without impacting the visual perception of the display. The wavelength-selective photovoltaic (WPV) element is visibly transparent, in that it absorbs selectively around the visible emission (or reflection) peaks generated by the display. The photovoltaic material is able to cover a portion or the entire surface area of the display, without substantially blocking or perceptually impacting the emission (or reflection) of content from the display. The incident light that is absorbed by the photovoltaic element is then converted into electrical energy to provide power to the device, for example.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of US Provisional Application No. 61 / 708,389, filed October 1, 2012, the contents of which are hereby incorporated by reference. technical field [0003] This application relates to the use of optoelectronic devices for devices or electronics. Background technique [0004] Mobile devices (e.g., e-reading devices, tablets, mobile phones, wearable electronic devices (e.g., watches, smart watches, and electronic glasses), etc.) use battery power that needs to be charged, if not recharged, in shorter periods of time. It also needs to be charged almost every day. Optoelectronic cells are being used to supplement battery life, and different approaches have been used to integrate optoelectronic cells into the structure of mobile devices including displays. In an example method, a translucent photovoltaic cell that absorbs visible light is placed on a display. In another approach, the opa...
