Photovoltaic cells are an established and increasingly important technology for the
production of renewable energy. 1 Despite the expanding use of inorganic semiconductors …

The design of novel conjugated polymers with appropriate frontier orbital energy levels, low
band gap (LBG) and suitable carrier transport properties are needed to improve the power …

The research on the polymer-based solar cells (PSCs) has attracted an increasing amount
of attention in recent years because PSCs pose potential advantages over mainstream …

To investigate the structural ordering of DCAE7T, DCAO7T and DCAEH7T in the solid state,
we performed X-ray diffraction (XRD) analysis for thin films spin-coated from CHCl 3 solution …

Inverted OPV devices based on sol-gel derived vanadium oxides (VO (x)) as an interfacial
layer are demonstrated. The VO (x) shows excellent characteristics as a hole-transporting …

Initially, the role of an alkyl chain on a conjugated polymer was to confer solubility of the rigid-
rod-like structure in common organic solvents. It is now apparent that the choice of …

Non-fullerene ternary organic solar cells (OSCs) are new promising candidates for future
applications in the area of organic photovoltaics. However, their low short-circuit current …

Solution deposition using high-boiling-point additives such as octanedithiol (ODT) provides
a simple and widely used fabrication option for improving the power conversion efficiencies …

Rational design and synthesis of polymeric semiconductors is critical to the development of
polymer solar cells (PSCs). In this work, a new series of benzodithiophene …

By utilizing Friedel− Crafts cyclization, we have successfully designed and synthesized a
ladder-type heptacyclic carbazole-dicyclopentathiophene (CDCT-C8) unit in which two outer …
