Modified fullerenes as acceptors in bulk heterojunction organic solar cells – a theoretical study

Abstract

In the present study, electronic structure calculations were used to provide strategies for designing poly(3-hexylthiophene) (P3HT)–fullerene-derivative-based donor–acceptor materials for use in high-efficiency bulk heterojunction organic solar cells (BHJ OSCs).

Grape bunches of novel conjugated chain bonded fullerene oligomers: design of a potential electron trap carbonaceous molecular material

“…Fullerene bucky-balls, particularly C 60 and its derivatives, have great attraction as electron acceptors [1][2][3] due to their unique spherical structures and high electron mobility and electronaccepting ability. [4][5][6] They are promising and extensively used as organic n-type semiconductors in organic photovoltaic and other electron devices.…”

Hybrid Steroid‐[60]Fullerene as n‐Type Material for Organic Photovoltaics

“…[34] Electronic structure calculations were used to provide strategies for designing P3HT-fullerene derivative-based donor-acceptor materials for use in high-efficient BHJ-OSC. [35] Considering our interests in the chemistry of fullerene and our expertise in steroids, herein, we report a straightforward synthetic methodology to obtain a novel hybrid material from the reaction of suitably functionalized epiandrosterone with [60]fullerene. Epiandrosterone is an important naturally occurring steroid hormone suited with and hydroxyl group able to easily be transformed in a malonic ester.…”

“…The production of bulk heterojunction solar cells (BHJ‐OSC) from poly(3‐hexylthiophene) (P3HT) and [6,6]‐phenylC 61 butyric acid methyl ester (PC 61 BM) with power efficiencies of over a 4 % has been reported [34] . Electronic structure calculations were used to provide strategies for designing P3HT‐fullerene derivative‐based donor‐acceptor materials for use in high‐efficient BHJ‐OSC [35] …”
