Abstract:
Sb 2 Se 3 was fabricated with a facile atmospheric pressure thermal evaporation procedure as counter electrode (CE) for dye‐sensitized solar cells (DSSCs). The introduction of a carbon nanoparticle (CNP) film as substrate was proved to facilitate Sb 2 Se 3 deposition, resulting in the formation of a Sb 2 Se 3 layer on the surface of carbon nanoparticles (denoted as CNP‐Sb 2 Se 3 ). Electrochemical characterizations demonstrate the intrinsic catalytic ability of Sb 2 Se 3 and better electrocatalytic activity and stability of Sb 2 Se 3 deposited on CNP film in catalyzing I 3 ‐ reduction. Evaporation temperature was found to affect the electrocatalytic activity of CNP‐Sb 2 Se 3 and a lower temperature of 400 o C was proved to be better in our case. As a result, the best performing DSSC with CNP‐Sb 2 Se 3 CE yields a power conversion efficiency of 6.26%, which is comparable to that based on Pt CE (6.47%).
