Dye-sensitized solar cells (DSSCs) have been widely investigated as one of the next-generation solar cells because of their easy fabrication and low of cost along with the good power conversion efficiency (PCE) especially under low light intensities. By tuning the color of sensitizers and thickness of mesoporous TiO2, DSSC can be made transparent, which is highly suitable for the energy harvesting windows. To realize transparent DSSCs, one of the plausible solutions is to utilize sensitizers bypassing the photons between the 500 nm-600 nm, where human eye is highly sensitive. Therefore, dyes absorbing in lower (<500 nm) or near infrared (NIR) wavelength region could be an amicable approach towards transparent/semi-transparent DSSCs. To compensate the loss of photon harvesting in the high eye-sensitivity region, utilization of the dye-cocktails of two different dyes with absorption in <500 nm (D-131) and >600 nm (SQ-140), respectively have been attempted in this present work.
