NOVELTY - The flexible array (10) of solar cells to charge portable electronic devices such as mobile phones or global positioning system devices, comprise an external connection point. The array has variations in color across the array, is formed by joining cells via conductive adhesive coated tape, wire, cable, metal braid, polyimide strip, rivets, eyelets, pins, spade clips and/or crimp terminals, and is encapsulated in a substantially transparent cover by hot lamination, cold lamination and/or vacuum sealing. The solar cells are located on a substrate, and have varying dimensions or areas.    USE - The flexible array of solar cells is useful to charge portable electronic devices such as mobile phones or global positioning system devices.    ADVANTAGE - The flexible array of solar cells achieves any desired electrical output, provides non-uniform appearance of color, is rugged, compact and lightweight, is resistant to reverse bias, and has shade tolerance and lower sensitivity to angle or quality of the light and to temperature fluctuations.    DETAILED DESCRIPTION - The flexible array (10) of solar cells to charge portable electronic devices such as mobile phones or global positioning system devices, comprise an external connection point. The array has variations in color across the array, is formed by joining cells via conductive adhesive coated tape, wire, cable, metal braid, polyimide strip, rivets, eyelets, pins, spade clips and/or crimp terminals, and is encapsulated in a substantially transparent cover by hot lamination, cold lamination and/or vacuum sealing. The solar cells are located on a substrate, have varying dimensions or areas, are provided in a range of shapes including circles, trapezoids, rectangles or squares, are photoelectrochemical cells and/or dye solar cells, are electrically interconnected by a flexible printed circuit board (PCB) or a continuous substrate such as working electrode or counter electrode, utilize metal substrates for one of their electrodes, are physically and electrically connected in the array at one edge of the cell, include tabs, and are physically and electrically connected by way of the tabs or by way of a support structure. The PCB design allows inclusion of diodes. The external connection point is attached to the PCB via a knitted, solder paste adhered, rivet, pin, eyelet and/or soldered positive and/or negative contacts. The substrate utilizes a camouflage pattern, which is achieved by either a pattern of colors or areas of varying reflectivity. The transparent cover has low light reflectivity. The surface and/or bulk absorption and reflection characteristics of the transparent cover are non-uniform. A color variation is present between cells in the array or within cells in the array. The color variation is achieved by variations in dyes between cells, variations in the characteristics of the particles of the semiconductor between cells, variations in the composition of redox electrolyte between cells, variations in the amount and/or concentration of the catalyst deposited as the counter-electrode between cells, the addition of a pigment to the electrolyte or to the dye of the cells and/or variations in the reflectivity of the working electrode between cells. The pigment includes an inorganic pigment. The color variation gives rise to an overall camouflage appearance. The connected edges of the cells are oriented towards a centre line of the array. The support structure includes printed circuit board. INDEPENDENT CLAIMS are included for:    (1) a portable charging device formed from arrays; and    (2) a method of forming an array of cells.
