Abstract Organic solar cells (OSCs) now approach power conversion efficiencies of 20%. However, in order to enter mass markets, problems upscaling and operational lifetime have be solved, both concerning the connection between processing conditions active layer morphology. Morphological studies supporting development structure–process–property relations are time‐consuming, complex, expensive undergo for which statistics, needed assess significance, difficult collected. This work demonstrates...
Abstract Organic photovoltaics (OPV) now can exceed 20% power conversion efficiency in single junction solar cells. To close the remaining gap to competing technologies, both fill factor and open‐circuit voltage must be optimized. The Langevin reduction is a well‐known concept that measures degree which charge extraction favored over recombination. It therefore ideally suited as an optimization target high‐throughput workflows; however, its evaluation so far requires expert interaction....
A novel donor-acceptor dyad, 4, in which the conjugated oligothiophene donor is covalently connected to fullerene PC71 BM by a flexible alkyl ester linker, synthesized and applied as photoactive layer solution-processed single-material organic solar cells (SMOSCs). Excellent photovoltaic performance, including high short-circuit current density (JSC ) of 13.56 mA cm-2 , achieved, leading power conversion efficiency 5.34% an inverted cell architecture, substantially increased compared other...
Abstract A method for organic solar cell (OSC) stability testing is presented that aims to provide more unique insight into the causes of degradation patterns OSCs. The involves using monochromatic light at high irradiation doses accelerate isolated mechanisms while monitoring device with a series in‐situ steady‐state and transient electrical measurements. experimental results are accompanied by drift‐diffusion simulations localize pathways. PM6:Y6‐based OSCs tested, which known show rather...
Abstract Bulk heterojunction organic solar cells (BHJ‐OSCs) are designed to overcome inefficient charge generation and limited exciton diffusion of semiconductors. However, there some disadvantages involving inherent voltage losses, microstructure control, operational instability. Bilayer (BL‐OSCs) without mixed regions free from these problems offer a platform explore the photophysical processes at donor–acceptor interface. Here, breakthrough for n‐i‐p BL‐OSCs in efficiency is reported. A...
While wavelength-dependent photodegradation of organic solar cells (OSCs) under visible light is typically discussed in terms UV/blue light-activated phenomena, we recently demonstrated degradation rates up to 660 nm for PM6:Y6. In this study, systematically investigated phenomenon a broad variety devices based on different donor:acceptor combinations. We found that the spectral composition used degradation, tuned range from 457 740 and high irradiances 30 suns, has crucial influence device...
