The invention relates to nanometer solar fabric photovoltaic surface skin. The nanometer solar fabric photovoltaic surface skin is prepared from glass fiber fabric substrate and nanocrystalline titanium dioxide powder; the glass fiber fabric substrate is woven by glass fibers serving as weft and warn yarns; the prepared glass fiber fabric substrate is soaked in 50 percent ethanol solution, and then is taken out and aired after 24 hours, and then is repeatedly washed in 95 percent ethanol solution for more than 10 times; an electric conduction film is prepared by the following steps of: preparing gaseous state nanocrystalline titanium dioxide by using the nanocrystalline titanium dioxide powder at high temperature, and placing the clean glass fiber fabric substrate for later use in anocrystalline titanium dioxide steam produced at the high-temperature environment; standing for more than 10 minutes and taking out; and naturally airing to obtain a layer of nanocrystalline titanium dioxide coating on the surface of the glass fiber fabric substrate. The nanometer solar fabric photovoltaic surface skin has the advantages of lightness, high flexibility, high efficiency, low price, wide application prospect and high economic and social benefits.
