Manufacturing of ink-sensitized solar cell by NANO technology

The hybrid ink-sensitized solar cell (ISSC) was manufactured by thin film techniques using Ultrasonic spray pyrolysis. Transparent conductive glass was manufactured by doping Indium-Tin Oxide (ITO), the (ITO) colloidal solution sprayed on glass substrate at 250 °C, the sheet resistance of (ITO) film was about (10 Ω/π) by using (Jandal-TFC), the transparent of thin film is about (85%) by using (UV-Vis) and the high peak of thin film was measured (250 nm) by using Atomic Force Microscopic (AFM). The photoelectrode (the anode) was manufactured by nano-titanium dioxide colloidal solution at absorption maximum 1.55 in wavelength (l_max=345 nm), was sprayed on (ITO) glass and the ink sensitized solution with polymer was sprayed on TiO₂ layer. The counter electrode (the cathode) was fabricated from the nano-carbon layer through its coating on (ITO) glass by electrodepositing method A small molecule based hole conductor, copper phthalocyanine, is used here to replace the liquid electrolyte in (DSSC) which putting between electrodes of cell when its assembling Photovoltaic parameters like short circuit current (I_SC), open circuit voltage (V_OC), fill factor (FF) and overall conversion efficiencies (η) for fabricated cell were 5.2 (mA/cm²), 500 mV, 26.92% and 1.88 under (100 mW/cm²) sunlight energy respectively and current-voltage curve (I-V).
