ABSTRACTTo provide a counter electrode with lower-cost and simple production method for dye-sensitized solar cells (DSSCs), we developed polyaniline/graphene nanoplatelet/multi-walled carbon nanotube (PANi/GNP/MWCNT) composite films growing on glass substrates by using chemical/electrochemical deposition method and on fluorine-doped tin oxide (FTO)/glass substrates by using electrochemical deposition method respectively. A proper weight ratio of PANi/GNP/MWCNT (1/0.0030/0.0045) composite film depositing on FTO substrate as counter electrode with sheet resistance of 8.25±0.13 Ω/sq for DSSCs yielded power conversion efficiency (PCE) up to 7.45±0.08%, which has potential to replace the conventional Pt cell (7.62±0.07%). In addition, we also fabricated the DSSCs composed of a proper weight ratio of PANi/GNP/MWCNTs (1/0.0045/0.0060) composite film depositing on glass substrate as counter electrode. The sheet resistance of resulting composite film was 59.34±12.34 Ω/sq. These solar cells with FTO-free counter electrode exhibited a PCE of 2.90±0.09%.

Pt catalytic nanoparticles on F-doped SnO2/glass substrates were prepared by polyol reduction below 200 °C. The polyol reduction resulted in better transparency of the counter electrode and high power-conversion efficiency (PCE) of the resultant dye-sensitized solar cells (DSSCs) compared to conventional thermal reduction. The PCEs of the DSSCs with 5 μm-thick TiO2 photoanodes were 6.55% and 5.01% under front and back illumination conditions, respectively. The back/front efficiency ratio is very promising for efficient bifacial DSSCs.

Lampblack prepared by using a traditional mustard oil lamp was mixed with printer toner in the ratio of 1:1 by weight and the composite was used as a low-cost catalyst for the reduction of tri-iodide ions in dye-sensitized solar cells (DSCs). The X-ray diffraction (XRD) of the lampblack showed that the lampblack contains a carbonaceous material of graphitic form. The adhesion test of the composite film on the counter electrode (CE) of the DSC showed that the composite film is firmly attached on the CE. The DSC with CE based on the composite of lampblack and printer toner yielded the overall light to electricity conversion efficiency of 3.20 % compared with 4.18 % efficiency of the DSC with CE based on platinum when the solar cells were tested in the simulated light of 100 mW/cm2.
