Résumé

Antimony triselenide (Sb2Se3) has possessed excellent optoelectronic properties and has gained interest as a light-harvesting material for photovoltaic technology over the past several years. However, the severe interfacial and bulk recombination obviously contribute to significant carrier transport loss thus leading to the deterioration of power conversion efficiency (PCE). In this work, we synergistically employ buried interface and heterojunction engineering to regulate the film growth kinetic and optimize the band alignment. Through this approach, the orientation of the precursor films is successfully controlled, promoting the preferred orientational growth of the (hk1) of the Sb2Se3 films. Besides, interfacial trap-assisted non-radiative recombination loss and heterojunction band alignment are successfully minimized and optimized. As a result, the champion device presents a PCE of 9.24% with short-circuit density (JSC) and fill factor (FF) of 29.47 mA/cm2 and 63.65%, respectively, representing the highest efficiency in sputtered-derived Sb2Se3 solar cells. This work provides an insightful prescription for fabricating high-quality Sb2Se3 thin film and enhancing the performance of Sb2Se3 solar cells.
