摘要：

MoSe2, a group VI TMDC, has been found to be highly stable against photocorrosion due to d-->d transitions and has a band gap of 1.4eV. Thus, it possesses high potential towards photoelectronic applications. As grown, MoSe2 based photoelectrochemical (PEC) solar cells are generally found to show low conversion efficiency, It has been shown here that cleaning and controlled chemical and thermal processing can lead to viable levels of photoconversion with high stability. The observed improvement in the behaviour of such solar cells has been attributed to improvements in various parameters like series resistance, minority carriers, diffusion lengths etc. (C) 2002 Elsevier Science B.V.
