Flexibility is the most prominent advantage of organic solar cells (OSCs) compared with traditional photovoltaic devices, showing an irreplaceable commercial potential. Currently, the maximum power conversion efficiencies (PCEs) of single-junction OSCs have been over 19% and 16% upon rigid and flexible substrates, respectively, which meet the criteria for
The short-circuit current (JSC) overestimation is a severe but common issue in low-light photovoltaic devices. This work demonstrated that the electrical edge effect, whether originated from conducting layer or interface doping, will lead to significant JSC and power-conversion efficiency overestimation of more than 100%. Furthermore, this work showed that
Non-fullerene acceptors (NFAs) have achieved breakthrough photovoltaic conversion efficiencies at the lab scale, giving rise to a new generation of organic photovoltaics (OPVs) that are tunable, solu...
The discovery of the photovoltaic (PV) effect is commonly ascribed to Becquerel (see Fig. A), who discovered a photocurrent when platinum electrodes, covered with silver bromide or silver chloride, was illuminated in aqueous solution (strictly speaking this is a photoelectrochemical effect) [1].Smith and Adams made the first reports on photoconductivity,
Historically organic photovoltaics (OPVs) have held the promise of low-cost synthetic materials and cost-effective roll-to-roll (R2R) production. 1 Low capital investment, rapid continuous production, and inexpensive materials have created the expectation of OPV to generate competitive costs for electrical production and low energy payback periods. 2 This evaluation,
In recent years, organic photovoltaics (OPVs) have experienced a significant increase in efficiency, reaching levels of up to 19% due to advances in materials engineering.

Solution-processed organic photovoltaics (OPVs) are expected to have an advantage over traditional solar technologies due to their promise of lightweight, semitransparency, vivid colors, and flexibility, 1, 2, 3 which could allow more cost-effective applications, such as wearable electronics, biomedical devices, and building-integrated PVs.
Organic photovoltaic (OPV) cells have recently undergone a rapid increase in power conversion efficiency (PCE) under AM1.5G conditions, as certified by the National Renewable Energy Laboratory (NREL), which have jumped from 11.5% in October 2017 to 18.2% in December 2020. However, the NREL certified PCE of large area OPV modules is still
The application of organic photovoltaic (OPV) cells to drive off-grid microelectronic devices under indoor light has attracted broad attention. As organic semiconductors intrinsically have less ordered intermolecular packing than inorganic materials, the relatively larger energetic disorder is one of the main results that limit the photovoltaic
Efforts to increase the mechanical stability of organic semiconductors and whole solar cells have required expertise in many areas, namely organic synthesis, molecular and continuum modeling, device fabrication, and testing in simulated real-world conditions. 11 While there is not yet a "recipe" for producing organic semiconductors that can resist any
