Article history: Copper phthalocyanine is a promising hole transporting material, which can be employed with solid Received 28 September 2015 state perovskite solar cells. Tetra methyl substituted copper phthalocyanine was presently studied as Received in revised form 4 November 2015 a hole transporting material and demonstrated improved performance with respect to unsubstituted Accepted 6 November 2015 copper phthalocyanine. This material shows a strong absorption in the Visible and Near IR part of the Available online 14 November 2015 electromagnetic spectrum contributing to the absorption of photons. Its LUMO and HOMO level are favourably positioned for injecting electrons and scavenging holes. Methyl substitution facilitates closer Keywords: molecular packing leading to a stronger extinction coefﬁcient, stronger – interaction and higher charge Hole transporting material carrier mobility.

Although other small-molecule HTMs may have signiﬁcant beneﬁcial impact on the Semiconductor nanocrystals and organic–inorganic perovskites production cost and robustness of the technology, to our knowl- are considered promising candidates for next generation solar cells edge, they have not succeeded to overpass 10–16% efﬁciency. due to the combination of superior electro-optical properties with Alternative
