It is clear that the current energy regimen, which relies on nonrenewable and polluting
energy sources, has unsustainable consequences for societal, economical, geopolitical, and …

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

A series of acceptor–donor–acceptor simple oligomer-like small molecules based on
oligothiophenes, namely, DRCN4T–DRCN9T, were designed and synthesized. Their …

Developing highly efficient photocatalyts for water splitting is one of the grand challenges in
solar energy conversion. Here, we report the rational design and synthesis of porous …

Solution processed single junction polymer solar cells (PSCs) have been developed from
less than 1% power conversion efficiency (PCE) to beyond 9% PCE in the last decade. The …

Owing to the intrinsically low dielectric properties, robust Coulomb interactions between
photoinduced electrons and holes lead to dramatically strong exciton effects in polymeric …

Three structurally identical polymers, except for the number of fluorine substitutions (0, 1, or
2) on the repeat unit (BnDT-DTBT), are investigated in detail, to further understand the …

To design efficient materials for organic photovoltaics (OPVs), it is essential to identify the
largest number of parameters that control their properties and build a model using these …

The performance of organic photovoltaic (OPV) material systems are hypothesized to
depend strongly on the intermolecular arrangements at the donor: fullerene interfaces. A …

Organic photovoltaic cells are promising in terms of their light weight, mechanically flexibility,
ease of processing and low cost. Establishing a predictive understanding between the …
