Abstract |
Tin (II) sulfide (SnS) is a promising candidate to replace current thin film light absorbing
materials in photovoltaics. SnS has a moderate band-gap (1.1-1.3 eV) and high absorption
coefficient. SnS thin films have been prepared by metal organic chemical vapor deposition
(MOCVD) from the reaction of Sn(dmamp)2 and H2S gas as the source materials. The
molecular structure of Sn(dmamp)2 is shown in fig. 1. SnS films were deposited on Si and
glass substrates at the deposition temperature of 200-400 ℃. Post annealing of SnS thin films
was carried out at 400 ℃ for 1 h under the H2S ambient. Hall measurement using van der
Pauw method indicate that the film has a p-type conductivity with a hole mobility of 13
cm2/V·s. Raman spectroscopy and x-ray photoelectron spectroscopy results show that SnS
thin film has no impurities or other binary phase detected inside the films. |
