• Environmental improvement

Though environmental improvement has been claimed for the application of nanotechnology to solar cells, several characteristics of the fullerene-based organic, and the dye-sensitized nanoparticulate, solar cell are not conducive to such improvement. These include relatively high energy and materials inputs in the production of nanoparticles, a relatively low solar radiation to electricity conversion efficiency, a relatively short service life, the use of relatively scarce metals and relatively poor recyclability, if compared with the multicrystal line Si solar cell which currently is the market leader. Moreover, the lack of data and the inability of current methods to handle hazards of nanoparticles generate problems in conducting comparative life cycle assessment of nanoparticulate solar cells. So far, the claimed environmental advantage can not be substantiated for fullerene-based and dye-sensitized nanoparticulate solar cells. There are options for the environmental improvement of these nanoparticulate solar cells, but actual development does not seem to focus on environmental improvement.
