In the following we provide a comprehensive review of singlet fission in organic materials.
We first sketch an outline of the underlying theory and then turn to molecular crystals …

The third generation of photovoltaic technology aims to reduce the fabrication cost and
improve the power conversion efficiency (PCE) of solar cells. Singlet fission (SF), an efficient …

Bulk-heterojunction organic photovoltaic devices with nonfullerene acceptors (NFAs) exhibit
efficient hole transfer with small interfacial energy offset, which results in power conversion …

Optoelectronic synapses can perceive and memorize visual information, making them
appealing for future bionic eyes or vision automation. Organic field-effect transistors are a …

The development of near‐infrared (NIR) organic light‐emitting diodes (OLEDs) is of growing
interest. Donor–acceptor (D–A) chromophores have served as an important class of NIR …

A cocrystal strategy with a simple preparation process is developed to prepare novel
materials for near‐infrared photothermal (PT) conversion and imaging. DBTTF and TCNB …

Singlet exciton fission transforms a molecular singlet excited state into two triplet states,
each with half the energy of the original singlet. In solar cells, it could potentially double the …

Abstract Benzo [d][1, 2, 3] triazole (BTA) unit is one of the most classic electron‐accepting
units (A) to construct donor (D)‐π‐A‐type photovoltaic polymers. However, the highest …

Singlet exciton diffusion plays a central role in the photovoltaic conversion in organic
photovoltaics (OPVs). Upon light absorption, singlet excitons are promptly generated in …

Blends of conjugated polymers and fullerene derivatives are prototype systems for organic
photovoltaic devices. The primary charge-generation mechanism involves a light-induced …
