Abstract :
Nanoparticulate TiO2-pyridine derivative monolayer/n-Si(111) assembly was fabricated by Langmuir-Blodgett (LB) technique from 4-[4′-N,N-(didodecylamino) stryll pyridium (PII), and its photovoltaic conversion properties were investigated by surface photovoltage spectroscopy. Sensitization effect of PII molecule as well as TiO2 nanoparticle on n-Si(111) is observed, and the photovoltaic response of this assembly is about 20 times as high as that of n-Si(111).
