The transfer of charge at the molecular level plays a fundamental role in many areas of
chemistry, physics, biology and materials science. Today, more than 60 years after the …

Polymer-based electronic devices are limited by slow transport and recombination of newly
separated charges. Built-in electric fields, which arise from compositional gradients, are …

We report an efficiency of 6.1% for a solution-processed non-fullerene solar cell using a
helical perylene diimide (PDI) dimer as the electron acceptor. Femtosecond transient …

Covalent organic frameworks (COFs) have emerged as a promising light-harvesting module
for artificial photosynthesis and photovoltaics. For efficient generation of free charge carriers …

Since its inception in 1995, significant advances in the field of bulk heterojunction (BHJ)
solar cells have been made and polymeric semiconductors are now considered to be one of …

Hierarchical structure of conjugated polymers is critical to dominating their optoelectronic
properties and applications. Compared to nonplanar conformational segments, coplanar …

Over billions of years, evolutionary pressure has facilitated the development of sophisticated
and diverse light-harvesting systems in photosynthetic organisms, enabling them to adapt to …

The origin and yield of charges in neat conjugated polymers has long been controversial. In
this paper, we review the body of literature that has been created over the past three …

Abstract Knowledge of the factors controlling excited state dynamics in excitonically coupled
dimers and higher aggregates is critical for understanding natural and artificial solar energy …

Organic photodetectors (OPDs) are attractive for their high optical absorption coefficient,
broad wavelength tunability, and compatibility with lightweight and flexible devices. Here we …
