Organic solar cells have the potential to become the cheapest form of electricity, beating
even silicon photovoltaics. This article summarizes the state of the art in the field …

The power conversion efficiencies (PCEs) of single‐junction organic solar cells (OSC) have
now reached over 18%. This rapid recent progress can be attributed to the development of …

Enhancing the luminescence property without sacrificing the charge collection is one key to
high-performance organic solar cells (OSCs), while limited by the severe non-radiative …

The nonradiative energy loss (∆ E nr) is a critical factor to limit the efficiency of organic solar
cells. Generally, strong electron-phonon coupling induced by molecular motion generates …

Recent advances in organic solar cells based on non-fullerene acceptors (NFAs) come with
reduced non-radiative voltage losses (Δ V nr). Here we show that, in contrast to the energy …

The fill factor (FF) of organic solar cells (OSCs), a critically important photovoltaic parameter,
is still sub-optimal, often less than 0.8. To further reduce the FF gaps with regard to the …

Energy loss within organic solar cells (OSCs) is undesirable as it reduces cell efficiency,,–.
In particular, non-radiative recombination loss and energetic disorder, which are closely …

Finding effective molecular design strategies to enable efficient charge generation and small
energy loss is among the long-standing challenges in developing high performance non …

Compared with inorganic or perovskite solar cells, the relatively large non‐radiative
recombination voltage losses (ΔVnon‐rad) in organic solar cells (OSCs) limit the …

Impressive short‐circuit current density and fill factor have been achieved simultaneously in
single‐junction organic solar cells (OSCs) with the emergence of high‐performance non …
