NOVELTY - Dye sensitized solar cell (30) comprises at least one dye (16) comprising substituted (E)-3-(4-((1Z,5Z,10Z,14Z)-15-(4-amino-phenyl)-10,20-diphenyl-2,3,23,24-tetrahydro-porphin-5-yl)-phenyl)-acrylic acid ester compounds (I) or their mixtures.    USE - Used as dye sensitized solar cell.    ADVANTAGE - The dye sensitized solar cell: utilizes (I), which has low toxicity, can be easily produced in large scale and allows possibility of modifying the organic and inorganic portions, thus absorption wavelength of the dye sensitizer can be modified.    DETAILED DESCRIPTION - Dye sensitized solar cell (30) comprises at least one dye (16) comprising substituted (E)-3-(4-((1Z,5Z,10Z,14Z)-15-(4-amino-phenyl)-10,20-diphenyl-2,3,23,24-tetrahydro-porphin-5-yl)-phenyl)-acrylic acid ester compounds of formula (I) or their mixtures.    M = 2H, Zn2+, Cu2+ or Sn4+;    R1, R2 = 6-12C alkyl;    R3 = H or CN;    R4 = H or alkyl; and    R5, R6 = H, alkyl or cycloalkyl.    INDEPENDENT CLAIMS are also included for preparing the dye sensitized solar cell, comprising either forming a first conductive layer (12) on the first substrate, forming a barrier layer on the first conductive layer, forming a titanium dioxide nanoparticulate layer (14), forming titanium dioxide microparticulate layer (13) on the titanium dioxide nanoparticulate layer, disposing a dye on the titanium nanoparticulate layer and/or the titanium dioxide microparticulate layer, where the dye comprises (I), 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 a first substrate comprising first conductive layer and titanium dioxide nanoparticulate layer, disposing a dye on the titanium dioxide nanoparticulate layer, where the dye comprises (I) and providing a second substrate comprising second conductive layer.
