A comparative study on the performance of photogalvanic cells with different photosensitizers for solar energy conversion and storage: D-Xylose-NaLS systems

Publication year: 2011brbSource:/b Energy, In Press, Corrected Proof, Available online 3 January 2011brMahesh Kumar, Bhimwal , K.M., GangotribrThe comparative performance of photogalvanic cells has been studied for solar energy conversion and storage by using Methyl Orange, Rose Bengal, Toluidine Blue and Brilliant Cresyl Blue as different photosensitizers with d-Xylose as reductant and Sodium Lauryl Sulphate (NaLS) as surfactant in the different systems. The photogeneration of photopotential are 890.0, 885.0, 945.0 and 940.0 mV whereas the maximum photocurrent is 625.0, 575.0, 510.0 and 480.0 μA, respectively. The short circuit current or photocurrent at equilibrium is 480.0, 460.0, 430.0 and 440.0 μA, respectively. The observed conversion efficiencies for Methyl Orange, Rose Bengal, Toluidine Blue and Brilliant Cresyl Blue with d-Xylose and Sodium…br Research highlights: ► The discussed photogalvanic cells have higher storage capacity and conversion efficiency of sunlight, in comparison to the present solar cells. ► A comparative performance of photogalvanic cells was studied by applying different photosensitizers (dyes) systems. ► A more reliable estimate of the maximum conversion efficiency and storage capacity are achieved 1.1057%–1.6245% and 96.29%, respectively. ► On the basis of sunlight conversion data, the observed maximum photocurrent and photopotential are 1200.0 μA and 2360.0 mV, respectively. ► The literature survey reveals that the reported results in the present research work are the highest so far.
