The S-MoOx xerogel is synthesized via sol-gel derived method.
S-MoOx solution and film feature superior solubility, morphology and electronic properties.
Performance comparable to device with PEDOT:PSS HTL achieved using sol-gel derived S-MoOx.
Wider temperature tolerant from room temperature to 250 °C for this S-MoOx layer.
Dramatically enhance the stability of the OSCs using S-MoOx replacement of PEDOT:PSS.
