The invention relates to a dye sensitive nanometer thin film solar battery with an electronic composite restraining structural layer. The battery structure is an ITO/TiO2 electrode for absorbing dye molecule/electrolyte/ an electronic composite restraining structure/a Pt counter electrode/ITO; the electrolyte is added between the ITO/TiO2 electrode for absorbing the dye molecule and the counter electrode on an ITO base plate to form the battery to be directly superimposed together, and the electrolyte can be encapsulated and sealed on the periphery of the battery by using package resin; and the electronic composite restraining structure is aluminum oxide, silicon oxide, polymer or P-shaped semiconductor materials evaporated or sprayed on both the counter electrode or/and TiO2 electrode.
