摘要: WSe2 crystals (photo-electrodes) have been grown via a vapour transport technique, employing SeCl4 as transporter photo-electrochemical (PEC) solar cells with n-WSe2/I-, I2/Pt fabricated. In order to improve upon the efficiency, effective crystal surfaces etched in aqua-regia. The authors obtained high PEC conversion up 17.1%. This corresponds most efficient WSe2-based cell reported so far. Evidence and arguments presented show that efficiency ( approximately 17.1%) is achieved due combined effect of improved quality, through transporter, decrease density surface steps consequent photo-etching.
