Hollow core-shell structured mesoporous MWCNT/carbon nanofiber composites by electrospinning and silica template as counter electrodes for dye-sensitized solar cells

Park S.H., Kim B-K., Lee W.-J., Chonnam National University, KR

The multi-walled carbon nanotube (CNT)-embedded carbon nanofibers with hollow core/highly mesoporous shell stucture (CNT/Meso-HACNF) are prepared by concentric electrospinning using poly(methyl methacrylate) (PMMA) as a pyrolytic core precursor with either CNT/polyacrylonitrile (PAN) or fumed silica [...]

Improve of Photovoltaic Performance of Dye-sensitized Solar Cell by Concentrating Solar Energy

Kim Y-W., Cho E., Choi S.C., Choi S.C., Lee D.W., Pusan National University, KR

Dye-sensitized solar cell (DSSC) is extremely promising because it is made of low-cost materials and does not need elaborate apparatus to manufacture against the silicon solar cell. Accordingly, the DSSC is constantly researched globally. One [...]

DFT calculations of IR and Raman spectra of Ru(bpy)2(CN)2 complex

Minaev B.F., Minaeva V.A., Minaeva V.A., Agren H., Girtu M., Bogdan Khmelnitskij national University, UA

In order to understand mechanism of electron transfer in dye-sensitized solar cell based on organic-inorganic junction we have studied the role of vibronic perturbations in metal-to-ligand and ligand-to-ligand charge transfer states excitations and in electron [...]

Large area optimized thin film nano solar cells on metal sheets

Toivola M., Peltola T., Miettunen K., Halme J., Aitola K., Lund P.D., Helsinki University of Technology, FI

We have upscaled stainless steel based dye-sensitized solar cell (DSC) from small, 0.32 cm2 active area laboratory sized test cells to 6 cm x 6 cm large area ”minimodule”. This is a continuation to our [...]

Thin nanostructured solar cells on metal sheets

Toivola M., Miettunen K., Halme J., Lund P., Helsinki University of Technology, FI

We have studied direct integration of nanostructured, dye-sensitized solar cells (DSC) on industrial sheet metals, used e.g. as building materials. To demonstrate an all-flexible, roll-to-roll producable and mechanically stable DSC, counter electrodes made of platinized [...]

Electrospun TiO2 Fibers as a Material for Dye Sensitizied Solar Cells

Duchoslav J., Rubáek L., Kavan L., Zukalová M., Procházka J., Elmarco Ltd., CZ

Electrospinning is a method for producing polymeric fabric with fibers ranging from 50 to 500 nm in diameter. It has been demonstrated that fibrous structure is preserved even after annealing when precursor of inorganic compound [...]

Dye-sensitized solar cell using a TiO2 nanocrystalline film electrode prepared by solution combustion synthesis

Wang C.M., Chungb S.L., National Cheng Kung University, TW

The nanocrystalline anatase TiO2 films were prepared and characterized in connection with their application to dye-sensitized solar cells. Solution combustion synthesis of TiO2 nanocrystalline film is based on hydrolysis, nitrated, and combustion reaction. The solution [...]
