Facile microwave synthesis, characterization, and solar cell application of selenium nanoparticles

چکیده مقاله

In the current study, selenium (Se) nanoparticles with hexagonal phase were synthesized by applying microwave irradiation using selenium tetrachloride as a starting reagent in distilled water at various conditions. Se nanoparticles were formed using hydrazine in short reaction time (4 min). The effects of reaction time, irradiation power, and types of surfactant including sodium dodecyl sulfate (SDS), polyethylene glycol 600 (PEG 600), and cetyltrimethylammonium bromide (CTAB) on the particle size of the product were investigated. To fabricate a FTO/TiO2/Se/Pt-FTO and FTO/Se/CdS/Pt-FTO solar cell, selenium film was directly deposited on top of the TiO2 and FTO glass prepared by Doctor’s blade method, respectively. Solar cell results indicate that an inexpensive solar cell could be developed by synthesis of Se nanoparticles through microwave method.
