The flexible dye-sensitized solar panel with an organic chromophore is formed from an organic chromophore dye in a polymer matrix. The organic chromophore dye is extracted from chard (B. vulgaris subsp. cicla). The polymer matrix may be formed from either poly(vinyl alcohol) or polystyrene. The flexible dye-sensitized solar panel with an organic chromophore is made by preparing a solution of the selected polymer in the dye extracted from the B. vulgaris subsp. cicla. The solution is coated on a glass plate and dried to form a thin film. The thin flexible film is removed from the plate, forming the flexible dye-sensitized solar panel with an organic chromophore.

Methods and devices for forming painted circuits using multiple layers of electrically conductive paint. In one aspect, a painted circuit includes a substrate (111) and one or more paint layer (106, 108, 110, 112, 114, 116, 120, 122) applied to the substrate, where the one or more paint layers each form an electrical component of the painted circuit. A given paint layer of the one or more paint layers includes a conductive paint formulation having a resistance that is defined by a concentration of conductive material that is included in the conductive paint formulation and a thickness of the given paint layer, and lower concentrations of the conductive material included in the conductive paint formulation provide a higher resistance than higher concentrations of conductive material.

The electrical connectors (12A, 12B) are separated from the functional layer in a base plate surface direction. The lead-out electrodes (11A, 11B) are disposed on an outer surface of the barrier packaging material (13A, 13B). Gaps between the barrier packaging material (13A, 13B) and the lead-out electrodes (11A, 11B) are sealed by a lead-out electrode seal (15).

A method for manufacturing a electronic device is provided having a current collector capable of a high specific charge collecting area and power, but is also achieved using a simple and fast technique and resulting in a robust design that may be flexed and can be manufactured in large scale processing. To this end the electronic device comprising an electronic circuit equipped with a current collector formed by a metal substrate having a face forming a high-aspect ratio structure of pillars having an interdistance larger than 600 nm. By forming the high-aspect structure in a metal substrate, new structures can be formed that are conformal to curvature of a macroform or that can be coiled or wound and have a robust design.
