“…Analyses of the life cycle CO 2 emission kW h À1 of current DS(S)Cs show a relatively high emission, if compared to current mcSi cells [12,20,21]. Similarly, present life cycle CO 2 emissions per kWh from fullerene-based cells exceed those of mcSi cells [22].…”

“…Though current databases include adequate data for the life cycle assessment of mcSi cells [20,49], this is quite different for nanoparticulate cells [6,12,21,22]. As yet, standard methodologies for life cycle assessment do not allow for the inclusion of nanoparticle hazard [23].…”

“…-producing nanoparticles may require much larger inputs of energy (in practice fossil fuels) and materials than the production of the same mass of larger-sized materials [13], -a relatively low efficiency in converting solar irradiation into electricity, if compared with mcSi cells [14,20,21], -a relatively short service life [15][16][17][18][19],…”

“…TiO 2 .nanoparticles may require at least a 3-4 times larger input of energy than conventional TiO 2 particles, whereas on a kg for kg basis the input of precursor may be increased by a factor 1.5-3.9 [13,24]. The production of fullerenes is energy intensive and is estimated [21] to require between 25 and 129 GJ of primary energy per kg C 60 . C 60 production can also be highly material intensive.…”

You will be contacted as soon as possible. a b s t r a c tThough 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 multicrystalline 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.
