Název v původním jazyce

New 3-dimensional nanostructured thin film silicon solar cells

Popis výsledku v původním jazyce

We present a ?bottom up approach for deposition of ZnO nanocolumns by direct low temperature hydrothermal synthesis and the results of complementary design with nano- or micro-holes etched into the ZnO (?Swiss cheese design). Electron beam lithography was used for defining the openings in resist for selective ZnO nanocolumns growth in the first case, optical lithography and reactive ion etching have been used to fabricate the holes into ZnO substrate in the later case. Monte Carlo modeling of these new,3D solar cells, using already existing materials is presented. Calculations show that stable efficiency of amorphous silicon p-i-n solar cells in over 12% range is possible and for the Micromorph cells efficiency can reach over 15%, with the layer thickness of amorphous Si below 200 nm and microcrystalline Si around 500 nm. The first ?proof of concept Micromorph cell with the ?Swiss cheese design is presented.
