SmSe2 films were electrosynthesised from aqueous tartrate bath onto a
variety of substrates. Photoelectrochemical characterization of SmSe2
films was carried out using 1 M KI-0.5 M KCl solution. It was found th
at the SmSe2 films are n-type and show photoactivity in above electrol
yte. The photovoltaic power output, photoresponse, spectral response,
Mott-Schottky plots, variation of diode ideality factor with temperatu
re and stability of SmSe2 films were studied and results are reported.
