Název v původním jazyce

3-dimensional amorphous silicon solar cells deposited on ZnO nanocolumns

Popis výsledku v původním jazyce

Hydrothermal growth offers the possibility to deposit high optical- and electronic-quality ZnO We report on novel 3-dimensional thin-film silicon solar cells. Amorphous silicon solar cells were deposited by plasma-enhanced chemical vapor deposition on arrays of hydrothermally grown ZnO nanocolumns. In order to get well-defined spacing and arrangement over the patterned area, we used electron beam lithography. Vertically aligned ZnO nanocolumns were grown in an aqueous solution of zinc nitrate hexahydrate and hexamethylenetetramine at 90 ?C, with a growth rate of 2 ?m/h. The morphology of the nanocolumns and cells was visualized by scanning electron microscopy. Nanocolumn-based a-Si:H solar cells show an increased short-circuit current in the red spectral range as compared to flat cells. Additionally, by means of rigorous 3-D simulations based on the finite element method, the optical behavior of a-Si:H and micromorph tandem solar cells on nanocolumns is evaluated.
