Organic-semiconducting hybrid solar cell
| DWPI Title: Organic-semiconducting hybrid solar cell has layer of transparent conductive metal oxide material that is mounted on layer of complex organic material, and layer of transparent laminar substrate mounted on layer of metal oxide material |
| Abstract: The embodiment of this invention lies on experimental evidence of photoconductivity activity of a hybrid solar cell, organic/chalcogenide. The device is made of thin layers of conductive indium-tin-oxide (ITO) on glass with a 100 nm layer of chalcogenide molybdenum di-sulfide (MoS2) and a thin layer of about ˜50 nm of complex organic compound assembled at room temperature. The device was tested to conventional electrical transport measurements in the regime of −1V to 1V under electromagnetic radiation simulator at 100 mW/cm2. Results indicate solar conversion efficiency of 2.48% and current density of 6.35 mA/cm2. |
| Use: Organic-semiconducting hybrid solar cell. |
| Advantage: The efficiency of the organic-semiconducting hybrid solar cell is increased. |
| Novelty: The solar cell has a first transparent solid laminar substrate and a first transparent conductive metal oxide layer that is mounted on the first substrate. A layer of chalcogenide semiconductor material (3) is sensitive to light and exhibits a porous matrix mounted on the first transparent conductive metal oxide layer. A layer of complex organic material (4) with a light black color composed of graphitic layers of aromatic carbons, allotropes of carbon and/or combination are mounted on the layer of chalcogenide semiconductor material. A second layer of transparent conductive metal oxide material is mounted on the layer of the complex organic material. A second layer of transparent laminar substrate is mounted on the second layer of transparent conductive metal oxide material. The first transparent solid laminar substrate and the second layer of transparent laminar substrate are constituted by amorphous glass or plastic acetate. |
