An ultrathin film of PSeTPTI, a donor semiconductor with high transparency of over 95%, is fabricated using a simple spin coating process. Due to the amorphous nature of PSeTPTI, the ultrathin film maintains good continuity and integrality. By utilizing transparent electrodes (WO 3 /Ag/WO 3 ), all transparent highly stable transistors based on such ultrathin PSeTPTI film are realized with transmittance as high as 93.7%.
