Organic photovoltaics (OPV) have the advantage of possible fabrication by energy‐efficient
and cost‐effective deposition methods, such as solution processing. Solvent additives can …

After the first report in 2008, diketopyrrolopyrrole (DPP)‐based small‐molecule photovoltaic
materials have been intensively explored. The power conversion efficiencies (PCEs) for the …

Recently, significant advances have been made in understanding and manipulating the
morphology of the active layer in bulk heterojunction (BHJ) organic photovoltaic (OPV) …

Thermal annealing is one of the most commonly applied post-processing techniques to
improve organic solar cell (OSC) performance. In this work, organic solar cells based on …

Organic photovoltaics (OPVs) and dye-sensitized solar cells (DSSCs) have drawn great
interest from both academics and industry, due to the possibility of low-cost conversion of …

In this work, we have synthesized a series of TDPP derivatives with different alkyl groups
such as n-hexyl (− C6H13) 3a, 2-ethylhexyl (-(2-C2H5) C6H12) 3b, triethylene glycol mono …

We report a series of solution-processable, small-molecule, donor materials based on an
architecture consisting of two diketopyrrolopyrrole (DPP) cores with different aromatic π …

Two new high-performance DPP-containing donor molecules employing a molecular
architecture with three DPP chromorphores (tri-DPP) in conjugated backbones are …

Three new oligothiophene derivatives with an acceptor–donor–acceptor structure
incorporating 1, 3-indanedione or the derivative of 1, 3-indanedione units as the terminal …

New π-conjugated copolymers based on naphtho [2, 3-b: 6, 7-b′] dithiophene-4, 5, 9, 10-
