Bulk heterojunction PTB7-Th: ICBA-based Optoelectronic Devices

Here, we have prepared the bulk heterojunction (BHJ) of Poly([2,6-4,8-di(5-ethylethexylthienyl)benzo[1,2-b;3,3-b]dithiophene]{3-fluro-2[(2-ethylhexyl)carbonyl]thieno[3,4b]thiophenediyl (PTB7-Th):Indene-C60 Bisadduct (ICBA) based composites to study the optoelectronic properties and utilize it in the photoactive layer of optoelectronic devices. The solution processing method has been used to prepare the composite thin film. Field emission scanning electron microscopy analysis validates the development of the composite of donor and acceptor polymers. The as-prepared composites were used to fabricate the device, having the photoactive layer made by composites PTB7-Th: ICBA. The enhanced absorption region was obtained in the UV-Visible spectra of the composite. The device demonstrated greater optoelectronic performance in the illumination condition. Higher interface quality may be ascribed to better optoelectronic performance since the ideality factor of the composite obtained in the dark is smaller than that achieved under illumination.
