NOVELTY - Dye-sensitized solar cell (30) comprises at least one dye (16) comprising substituted (E)-2-cyano-3-(5-vinyl-thiophen-2-yl)-acrylic acid compound (I).    USE - The dye-sensitized solar cell is useful in photovoltaic devices.    ADVANTAGE - The dye-sensitized solar cell: does not suffer from the lack of red light and near infra red absorption, as compared to conventional solar cells; and can be manufactured in an economical manner.    DETAILED DESCRIPTION - Dye-sensitized solar cell (30) comprises at least one dye (16) comprising substituted (E)-2-cyano-3-(5-vinyl-thiophen-2-yl)-acrylic acid compound of formula (I).    R1 = sulfur or oxygen containing 9,10-dihydro-acridine of formula (II) or (III);    X1, X2 = O or S;    X3 = absent or 2-5C alkenyl;    R4 = alkoxyaryl or 3-18C alkyl;    R5 = alkoxy;    R6 = alkoxy; and    R2, R3 = H or 3-18C alkyl.    INDEPENDENT CLAIMS are also included for preparing the dye sensitized solar cell, comprising either: forming a first conductive layer (12) on a first substrate (10), forming a barrier layer (11) on the first conductive layer, forming a titanium dioxide nanoparticulate layer, forming a titanium dioxide microparticulate layer on the titanium dioxide nanoparticulate layer, disposing the dye on the titanium dioxide nanoparticulate layer and/or the titanium dioxide microparticulate layer, forming a second conductive layer on a second substrate, and providing a regenerating composition between the second conductive layer and the barrier layer; or providing the first substrate comprising the first conductive layer and titanium dioxide nanoparticulate layer, disposing the dye on the titanium dioxide nanoparticulate layer, and providing the second substrate comprising the second conductive layer.
