Study of dye sensitized solar cells based on ZnO photoelectrodes deposited by laser ablation and doctor blade methods

Dye alami dari daun pandan, akar kunyit dan biji black rice telah dipreparasi dalam larutan etanol sebagai sensitiser pada dye sensitized solar cells (DSSC). Dye campuran dipreparasi dengan perbandingan volume 1 : 1 juga diteliti sebagai sensitiser pada DSSC. Metoda doctor blade dipakai untuk menumbuhkan lapisan tipis TiO2. Karakterisasi spektrofotometer UV-Vis dilakukan pada larutan dye untuk mengamati panjang gelombang yang diserap dye dan menghitung energi gap dye. Dari perhitungan diperoleh energi gap dye 1,387- 1,777 eV. Sedangkan dari karakterisasi arus tegangan (I-V), diperoleh efisiensi terbesar dye tunggal 0,056% dari dye kunyit dan efisiensi terbesar dye campuran 0,207% dari dye campuran black rice dan kunyit. Penggunaan dye campuran dapat meningkatkan performa dan efisiensi DSSC secara signifikan.

In this study, nano-crystallized TiO2 photoelectrodes prepared by doctor-blade method on ITO-PEN substrate applied on flexible tandem dye sensitized solar cells (DSSCs) have been investigated by field emission scanning electron microscopy (FE-SEM), UV-Vis spectrophotometer (UV-Vis), and I-V characteristics analyses. In the analysis of FE-SEM, TiO2 thin films prepared by doctor-blade method have the porous structure. The analyses of UV-Vis show that N3 and black dye could be adsorbed on the TiO2 thin films, and the absorption wavelength of TiO2 photoelectrodes could be obviously promoted from the ultraviolet ray to the visible light scope with N3 and Black dye adsorbed. It is great help for conversion efficiency of DSSCs. Under the irradiation of the sunlight simulator (AM 1.5,100 mW/cm2), the flexible dye-sensitized solar cell with double sensitized layers has the best conversion efficiency η =5.59 %.
