New generation of biomorph integrated with TCO and thermoelectric to enhance efficiency in wide solar spectrum solar cell

摘要

A Novel Bio-Organic material, named Cooperative Binary Ionic (CBI) solid, based on chlorophyll type nano structures were self assembled onto ZnO and BiTe Nano Wires (NWs) as an active layer of a new concept of thermoelectric-organic solar cell. The quality of the organic coating is extremely good and controlled in the range of 0.5–10 nm. 5nm of the CBI onto the ZnO NWs showed a photo efficiency of 3% at 0.2 suns illumination while the thermoelectric current of the BiTe NWs increased by 1% at 1 sun. Optoelectronic and structural properties of the CBI and the integrated device are discussed.
