摘要：Chemical exfoliated ultra-thin MoS₂ nanosheets (NSs) with well 2D structure were demonstrated for interfacial layers and Ag nanowires composite transparent electrode in polymer solar cells (PSCs). The smooth and uniform n-type and p-type (after the plasma treatment) MoS₂ NSs could improve fill factor of devices and light absorption in active layer. The optimized Ag nanowires–MoS₂ NSs (AgNW-MoS₂ NSs) transparent electrode presented a low sheet resistance of 9.8 Ω sq⁻¹, and the corresponding transmittance also exhibited a high value of 93.1% at 550 nm. As a result, ITO-free PSCs based on AgNW-MoS₂ NSs/n-MoS₂ NSs cathode and p-MoS₂ NSs/Ag anode achieved a highest PCE of 8.72%. Furthermore, a high efficiency (6.55%), large area and low cost semi-transparent power-generating glass was obtained, after reducing the thickness of top Ag electrode from 100 nm to 30 nm. To our best knowledge, it is the highest performance for semi-transparent PSCs devices reported up to now. The novel semi-transparent power-generating glass showed good performance and color purity for commercial applications in the near future.
