| titleOfInvention | Novel polymer compound, and solar cell or apparatus for photodetection comprising same |
| abstract | The present invention relates to a novel polymer compound and a solar cell or an apparatus for photodetection comprising the same, wherein the novel polymer compound according to the present invention forms a weak donor-weak acceptor structure and can be used as an organic solar cell or an organic photodetector. The novel polymer compound exhibits weak donor and weak acceptor properties, respectively, from fluorination at the donor site and from alkoxy substitution at the acceptor site. The weak donor-weak acceptor structure of the novel polymer compound according to the present invention can effectively increase the band gap as compared to the conventional donor-acceptor structure of the prior art and introduce fluorine and oxygen atoms at appropriate positions of the derivative, and thus can induce a good superposition of π- π orbital to greatly improve the planarity of the entire polymer. As a result, the polymer compound according to the present invention is made as a film and exhibits an absorption spectrum similar to an absorption spectrum of P3HT and exhibits a HOMO energy (-5.57 eV) lower than a HOMO energy of P3HT (-5.06 eV). Due to the low HOMO value, the improved power conversion efficiency compared with the prior art can be exhibited. For the organic photodetector, the S-F and S-O dipole-dipole interaction of the novel polymer compound according to the present invention maintains a constant responsivity and exhibits excellent photodetectability even in a thick photoactive layer of 470 nm. In particular, the novel polymer compound according to the present invention can be usefully used as an organic solar cell such as a cell having a series structure and a photodetector such as an X-ray detector. |
