Photocurrent enhancement by surface plasmon resonance of silver nanoparticles in highly porous dye-sensitized solar cells.
Localized surface plasmon resonance (LSPR) by silver nanoparticles that are photochemically incorporated into an electrode-supported TiO(2) nanoparticulate framework enhances the extinction of a subsequently adsorbed dye (the ruthenium-containing molecule, N719). The enhancement arises from both an increase in the dye's effective absorption cross section and a modest increase in the framework s...
متن کاملLaminating solution-processed silver nanowire mesh electrodes onto solid-state dye-sensitized solar cells
Solution processed silver nanowire meshes (Ag NWs) were laminated on top of solid-state dye-sensitized solar cells (ss-DSCs) as a reflective counter electrode. Ag NWs were deposited in <1 min and were less reflective compared to evaporated Ag controls; however, AgNW ss-DSC devices consistently had higher fill factors (0.6 versus 0.69), resulting in comparable power conversion efficiencies (2.7%...
متن کاملInvestigation of Silver Particles Forming on Surface of Silver Bromide Micro-Crystals
The regularities of formation and electronic characteristic of photolytic silver on the surface of sols and microcrystals (MC) AgBr of various sizes and habits, as well primitive, as subjected to chemical sensitization was explored by transmission electronic microscopy (TEM) and x-ray photoelectron spectroscopy (XPS) methods. XPSresults were compared to condition of silver in sols and MC AgBr, ...
متن کاملEvidence for trimers evaporation in silver bromide clusters
Metastable fragmentation channels of free silver bromide clusters (AgnBrp) + are reported. The large majority release a neutral trimer (AgBr)3. This is interpreted in the frame of ab initio DFT calculations with 19-electron pseudopotential on silver atom. The stability, the structural and electronic properties of (AgnBrp) (+) (n = 6, p = n, n− 1) are examined. The structures of the clusters are...
متن کاملComplex Formation and Photoreduction Processes in Sulphur Doped Silver Bromide
The dark conductivity of annealed silver bromide single crystals, containing trace amounts of silver sulfide, has been measured as a function of dopant concentration. At 21 ° C the conductivity exhibited a more rapid than linear increase with silver sulfide concentration at levels below 8 ppm. At 4 ppm, the lowest level achieved, a limiting dependence of the conductivity upon the fourth pwoer o...
