However, due to difficulties related with nanotube growth on sputtering samples, the project was refocused in the study of nanotubes on titanium plates with determinate conditions before continuing next parts. After, we visit new labs to sputtering samples that we needed to go on with the work of anodizating metal film for building cells. Then, during next step we realize that new conditions with sputtering samples had appeared to achieve nanotubes. With methods and experience obtained on first step, anodizating on plates, we tried to reproduce nanotube conditions on sputtering samples unsuccessfully. Nevertheless a TiO2 nanoporous structure was found and used to fabricate two cells. These cells had not the performance that we expected, but served us to understand that electric behavior existed and could be improved in next works. However, I would like to note that anodization samples on plates were an important part in this work and that without it, it would have been impossible to achieve anything during sputtering samples. In the same way, ESEM image spectrum depending on temperatures could be interesting for next projects. Is important to note that commented solution regarding of detaching film during anodization consisting on a sputtering double-layer would have been the better choice for continuing the experimental part anodizating the sputtering samples from Padova. In the same way, longer deposition times will be necessary to achieve competitive thickness as is reported in literature to get optimal cell conditions. At this point, although the project was carried out with all available physical and material means, it would have been much better to have at our disposal, at least in the same city, fundamental elements and devices that would have allowed us the full cell fabrication.+-
