In this study, we investigated the effect of electrolyte composition, photoanode thickness, and the additions of GuSCN (guanidinium thiocyanate), NMB (N-methylbenimidazole), and SiO2 on the photovoltaic performance of DSSCs (dye sensitized solar cells). A bifacial DSSC is realized and irradiated from front and rear sides. The devices give maximum photovoltaic efficiencies for 70% PMII (1-propyl-3-methyl-imidazolium iodide)/30% (EMIB(CN)(4)) (1-ethyl-3-methyl-imidazolium tetracyanoborate) electrolyte composi...

In this study, the photovoltaic properties of poly(triphenylamine-thiazolo[5,4-d]thiazole) alternating copolymer dye in bulk heterojunction polymer solar cells were examined. The copolymer is a red colored dye material with high thermal stability, good solubility and low-band gap energy. The band gap energy of the polymer was determined as 1.36 eV. The conductivity of the polymer thin film was measured as 1.5x10(-5) S/cm. The polymer solar cells were fabricated using the different ratios of the blends of th...
Photovoltaic performance of Gallium-doped ZnO thin film/Si nanowires heterojunction diodes
Akgul, Guvenc; Akgul, Funda Aksoy; Ünalan, Hüsnü Emrah; Turan, Raşit (2016-04-12)
In this work, photovoltaic performance of Ga-doped ZnO thin film/Si NWs heterojunction diodes was investigated. Highly dense and vertically well-aligned Si NW arrays were successfully synthesised on a p-type (1 0 0)-oriented Si wafer through cost-effective metal-assisted chemical etching technique. Ga-doped ZnO thin films were deposited onto Si NWs via radio frequency magnetron sputtering to construct three-dimensional heterostructures. Photovoltaic characteristics of the fabricated diodes were determined w...
Photovoltaic properties of benzotriazole containing alternating donor–acceptor copolymers: Effect of alkyl chain length
Baran, Derya; Balan, Abidin; Stubhan, Tobias; Ameri, Tayebeh; Toppare, Levent Kamil; Brabec, Christoph J. (Elsevier BV, 2012-12)
A series of variable alkyl chain length substituted donor-acceptor (D-A) conjugated polymers with thiophene ring as the donor and benzotriazole moiety as the acceptor has been investigated in bulk heterojunction solar cells. The optical and electrochemical properties showed that the absorption onsets and the energy levels of the copolymers were not affected by alkyl substitution revealing 1.9 eV of optical band gap. The morphologies of the blend film can be fine-tuned by increasing the chain length attached...
