Summary: This study demonstrates that the addition of ZCCF3 as a third component can stabilize the classical Y6-based binary organic solar cells. ZCCF3 has a higher glass transition temperature (T-g) than Y6 and high miscibility with Y6, resulting in a diffusion-limited Y6:ZCCF3 alloy when blended with the polymer donor. As a result, the optimal PM6:Y6:ZCCF3 devices achieve a champion power conversion efficiency of 18.54% and can retain 80% initial efficiency for up to 360 hours. This study highlights the importance of the high T-g and hyper-miscible accepter alloys of the third component in achieving highly efficient and stable organic solar cells.

Summary: Strategies have been developed to suppress the microcavity effect in transparent and top-emitting PeLEDs by enhancing electrode transmission and extending the optical cavity length. A record high total external quantum efficiency (EQE) of 16.1% in a transparent PeLED with Lambertian emission was achieved by depositing high refractive index molybdenum oxide on the semitransparent cathode. Additionally, a high EQE of 13.6% was achieved in a top-emitting device with quasi-Lambertian emission by increasing the optical distance between reflective layers and enhancing electrode transmission. The nanopatterned structure effectively suppressed waveguide mode and surface plasmon polariton dilapidation in top-emitting PeLEDs, paving the way for potential applications in both traditional and novel transparent displays.

Summary: A comparison of organic single crystals of different dimensions but with the same material reveals insights into their carrier injection mechanism. Two-dimensional (2D) and microrod single crystals with identical crystalline structure of a thiopyran derivative, C8-SS, were grown on a glycerol surface. Organic field-effect transistors (OFETs) based on the 2D C8-SS single crystal exhibit superior performance, especially in contact resistance (RC). RC is found to be influenced by the resistance of the crystal bulk in the contact region, with the 2D OFETs having significantly reduced RC due to their tiny thickness. The 2D OFETs demonstrate high operational stability and channel mobility up to 5.7 cm2/V center dot s, highlighting the potential of 2D molecular single crystals in organic electronics.
