Fabrication and characterization of PCBM:P3HT bulk heterojunction solar cells doped with silicon naphthalocyanine

Abstract

[6,6]‐phenyl C61‐butyric acid methyl ester: poly(3‐hexylthiophene) bulk heterojunction solar cells doped with silicon naphthalocyanine were fabricated and characterized. Photovoltaic properties of the solar cells with inverted structures were investigated by optical absorption, current density‐voltage characteristic, incident photon to current conversion efficiency, and internal quantum efficiency. The silicon naphthalocyanine blended as the third component absorbed near‐infrared light. Microstructure of the solar cells was investigated by X‐ray diffraction, and energy levels of the solar cells were discussed. (© 2013 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)

Fabrication and Characterization of PCBM: P3HT-based Thin-film Organic Solar Cells with Zinc Phthalocyanine and 1,8-Diiodooctane

“…P3HT nanowires would be dispersed in the PCBM amorphous matrix, which had already been confirmed by XRD and transmission electron microscopy analyses in the previous work [15]. Figures 10 and 11, referring the previous models and mechanisms [3,[15][16][17][18][19]. If the ZnPc molecules exist in the PCBM domain, charge transfer does not occur, as shown in Fig.…”

“…Addition of the third components such as phthalocyanines, naphthalocyanines and low-band-gap polymers is expected to absorb light that the P3HT and PCBM cannot collect. Since phthalocyanines absorb near-infrared light, effects of addition of silicon phthalocyanine, silicon naphthalocyanine or germanium phthalocyanine to the P3HT: PCBM system were investigated [11][12][13][14][15][16][17]. Solubilized metal phthalocyanines (MPc) could be dissolved in organic solvents, and the application for the device process using a spin-coating method could be expected.…”

Fabrication and characterization of silicon naphthalocyanine/fullerene-based photovoltaic devices with inverted structures

“…Silicon 2,3-naphthalocyanine bis(trihexylsilyloxide) (SiNc) was selected as a p-type semiconductor material in the present work. The SiNc absorb light in the near-infrared region [18,19], and fullrerne/SiNc systems are expected to provide photoelectric conversion in the near-infrared region, which will be applied for tandem solar cells with high efficiency. C60 fullerene and [6,6]-phenyl-C61-butyric acid methyl ester (PCBM) were also used as n-type semiconductor materials in the present work.…”
