Characterization of photovoltaic cells using poly(phenylenevinylene) doped with perylenediimide electron acceptors

Abstract

The performance of a sandwich junction device based on doped 1,4-bis(2-ethylhexyloxy)phenylenevinylene (BEH-PPV) is reported. The power conversion efficiency is dependent on the doping level, external load, and work function of the cathode. The increase in power conversion efficiency (ηe=0.8%) is due to efficient charge separation resulting from photoinduced electron transfer from the BEH-PPV donor to the perylene dicarboximide acceptor.

The Rylene Colorant Family—Tailored Nanoemitters for Photonics Research and Applications

“…Calculations on energy-minimized structures suggest diameters of about 5 nm (Figure 11). In addition to the number, the orientation of the chromophores was varied by attaching the PMI chromophores in the meta (24, 25) or para positions (22,23) of the outer phenyl groups of the dendritic scaffold.…”

Antifreeze Glycoproteins—Preventing the Growth of Ice

“…To obtain a thorough understanding of the self‐organization of a conjugated molecule at surfaces, one needs to gain insight into the accuracy and reproducibility of growth from solution; this can be achieved by changing a variety of experimental conditions 10. In this work, we studied the self‐organization of an n‐type molecule, perylenetetracarboxdiimide (PDI),11–15 which is known to possess high thermal and photo stability,16 together with an absorption in the visible part of the spectrum, high fluorescence quantum yield, and high electron affinity 17. For these reasons, it is considered to be a promising candidate for applications in organic solar cells 18.…”

Supramolecular self-assembly study of a flexible perylenetetracarboxylic diimide dimer in Langmuir and Langmuir–Blodgett films

“…The unique properties of PDIs, such as strong absorption and emission, good semi-conductivity, excellent thermal and chemical stabilities, have attracted extensive interest in the applications in photovoltaic cells [2][3][4][5][6][7], chemical sensors [8][9][10][11], electroluminescent devices [12][13][14][15], and organic field effect transistors (OFETs) [16][17][18][19]. The orderness of PDI molecules in the device has been proved to be crucial for the device performance.…”
