Claim Text:
1. A dye-sensitized solar cell, comprising: a first substrate and a second substrate arranged to face each other; a first electrode interposed between the first and second substrates, wherein the first electrode comprises an inorganic oxide layer and a dye layer chemically absorbed into the inorganic oxide layer to provide excited electrons; a second electrode disposed opposite to the first electrode, wherein the second electrode is interposed between the first and second substrates to thereby allow an electric current to flow; a first interface bonding layer configured to facilitate the interface bonding to the inorganic oxide layer, wherein the first interface bonding layer is disposed on the inorganic oxide layer; a second interface bonding layer configured to prevent an inverse current, wherein the second interface bonding layer is disposed on the first interface bonding layer; a light scattering layer interposed between the first and second interface bonding layers, said light scattering layer increasing optical absorption; and solid electrolytes interposed between the first and second electrodes, wherein the solid electrolytes comprise polymer nanofibers fabricated by an electrospinning method and provide electrons to the dye layer by an oxidation-reduction reaction; wherein the first and the second interface bonding layer are each independently formed from inorganic oxides in the form of nanoparticles having an average diameter between 1 and 50 nm; and wherein the light scattering layer is formed from inorganic oxides in the form of nanoparticles having an average diameter between 100 and 500 nm.
