Title: Customized color patterning of photovoltaic cells

Abstract

Photovoltaic cells and photovoltaic modules, as well as methods of making and using such photovoltaic cells and photovoltaic modules, are disclosed. More particularly, embodiments of the photovoltaic cells selectively reflect visible light to provide the photovoltaic cells with a colorized appearance. Photovoltaic modules combining colorized photovoltaic cells may be used to harvest solar energy while providing a customized appearance, e.g., an image or pattern.

  • In a stack of diodes forming a vertical multijunction photovoltaic cell, an inversely connected diode is firmly secured to this stack with possible insertion of a intermediate wafer made from a conducting material.
  • A photovoltaic power generation system that includes a solar panel is described herein. The solar panel includes a photovoltaic sub-module, which includes a group of microsystem enabled photovoltaic cells. The group includes a first string of photovoltaic cells, a second string of photovoltaic cells, and a differing photovoltaic cell. Photovoltaic cells in the first string are electrically connected in series, and photovoltaic cells in the second string are electrically connected in series. Further, the first string of photovoltaic cells, the second string of photovoltaic cells, and the differing photovoltaic cell are electrically connected in parallel. Moreover, the differing photovoltaic cellmore » is used as a bypass diode for the first string of photovoltaic cells and the second string of photovoltaic cells.« less
  • This patent describes an apparatus comprising mechanically stacked solar cells, comprising: a base support having opposed major surfaces; a first heat spreader-electrical contact contacting the base support on a major surface thereof which is incident to solar radiation; means for electrically contacting the first heat spreader-electrical contact; a first insulating spacer surrounding the heat spreader-electrical contact, the first insulating spacer having a space therein for a photovoltaic cell; a first photovoltaic cell having opposed major surfaces and electrically contacting the heat spreader-electrical contact on its major surface opposed to solar radiation, the first photovoltaic cell having a band gap energymore » responsive to solar radiation of predetermined wavelengths; means for electrically contacting the other major surface of the first photovoltaic cell which is incident to solar radiation; a second insulating spacer contacting the first insulating space and having a space therein for a second photovoltaic cell; and a second photovoltaic cell having, opposed major surfaces, the second photovoltaic cell having a band gap energy responsive to solar radiation of shorter wavelengths than the first photovoltaic cell.« less
  • Electrical interconnections for a large area photovoltaic cells, electrical interconnections for adjacent large area photovoltaic cells and the methods of producing those connections are disclosed herein. The cells are, preferably, of the type which include a plurality of electrically isolated, small area segments sharing a common substrate, a semiconductor body atop the substrate and a transparent, conductive coating atop the semiconductor body. The electrical interconnections include: an electrically-conductive strip interconnecting the small area segments of each large area to provide a first electrode of that cell; and access to the substrate from the layered surface of each large area cellmore » to provide the second electrode of that cell. The electrodes may be electrically-interconnected in series or parallel.« less
  • Photovoltaic modules which comprise back-contact solar cells, such as back-contact crystalline silicon solar cells, positioned atop electrically conductive circuit elements affixed to a planar support so that a circuit capable of generating electric power is created. The modules are encapsulated using encapsulant materials such as EVA which are commonly used in photovoltaic module manufacture. The module designs allow multiple cells to be electrically connected in a single encapsulation step rather than by sequential soldering which characterizes the currently used commercial practices.
