Abstract

original image

Illustrious pair: A tandem solar cell employs a front sub-cell with a ZrO2-doped nanostructured TiO2 and an organic dye to harvest 400–750 nm sunlight and a back sub-cell with another organic dye and a normal TiO2 electrode to capture 500–800 nm sunlight. A high VOC and JSC are achieved in the visible region of the solar spectrum, and at the same time to near-IR light is harvested.
