Increase of the efficiency of qua solar cells by a synergy between distinct nanoparticle sizes
A quasi-solid state dye-sensitized solar cell has been constructed by employing a nanocomposite organic-inorganic solid gel electrolyte. The titania film was a combination of nanoparticles of two distinct sizes obtained by separate sol-gel syntheses using different organic templates. The synergy between these entities raised cell efficiency to 6.9% under 1 sun. This value is very high, considering the fact that it is obtained with a quasi-solid state cell.
