Effect of nickel oxide thin films on photoconversion efficiency in zinc oxide dye-sensitized solar cells

ZnO dye-sensitized solar cells (ZnO DSSCs) with different thickness of NiO thin films coated in photo-electrode and counter-electrode were investigated. NiO thin films were prepared by thermal evaporation of NiO onto FTO glass substrate. The films were characterized by FE-SEM. For the photo-electrod...

Wongratanaphisan D. Gardchareon A. Choopun S. ZnO dye-sensitized solar cells (ZnO DSSCs) with different thickness of NiO thin films coated in photo-electrode and counter-electrode were investigated. NiO thin films were prepared by thermal evaporation of NiO onto FTO glass substrate. The films were characterized by FE-SEM. For the photo-electrode, NiO thin films were coated on ZnO with 0.2, 0.6, 1.1 and 2.2 mg to form a barrier layer. For the counter-electrode, NiO thin films were coated on FTO glass with 5.4, 10.8, 16.2 and 21.6 mg in order to increase a surface-to-volume ratio. The photoconversion efficiency of ZnO DSSCs was measured under illumination of stimulated sunlight obtained from solar simulator with the radiant power of 100 mW/cm2. It was found that ZnO DSSCs coated with 0.6 mg NiO in photo-electrode and 10.8 mg in counter-electrode exhibited the highest photoconversion efficiency of 1.00% and 0.92%, respectively. The enhancement of photoconversion efficiency with NiO coating maybe explained by decreasing of charge recombination in photo-electrode and increasing of active surface area in counter-electrode. © (2011) Trans Tech Publications. 2017-09-28T06:45:09Z 2017-09-28T06:45:09Z 2011-10-03 Book Series 02555476 2-s2.0-80053251269 10.4028/www.scientific.net/MSF.695.509 https://www.scopus.com/inward/record.uri?partnerID=HzOxMe3b&scp=80053251269&origin=inward http://cmuir.cmu.ac.th/jspui/handle/6653943832/42983
