Journal ArticleDOI
Perovskite solar cell with low cost Cu-phthalocyanine as hole transporting material
TL;DR: In this article, low cost copper phthalocyanine has been used as hole-transporting material for the construction of organolead halide solid state perovskite solar cells.
Journal ArticleDOI
A single atom change “switches-on” the solar-to-energy conversion efficiency of Zn-porphyrin based dye sensitized solar cells to 10.5%
Lydia Cabau,Challuri Vijay Kumar,Antonio Moncho,John N. Clifford,Núria López,Emilio Palomares +5 more
TL;DR: In this paper, the 2,1,3-benzothiadazole (BDT) group was used as a π-conjugated linker for porphyrin sensitizers in Dye Sensitized Solar Cells (DSSCs).
Journal ArticleDOI
Study of perovskite solar cells synthesized under ambient conditions and of the performance of small cell modules
TL;DR: In this article, solid state hybrid organic-inorganic solar cells have been made by employing a layer structure of nanoparticulate titania, organometal halide perovskite and spiro-MeOTAD as hole transporter.
Journal ArticleDOI
Subphthalocyanine as hole transporting material for perovskite solar cells
Georgia Sfyri,Challuri Vijay Kumar,Gokulnath Sabapathi,Lingamallu Giribabu,Konstantinos S. Andrikopoulos,Elias Stathatos,Panagiotis Lianos +6 more
TL;DR: In this paper, a non planar 14-π aromatic subphthalocyanine has been introduced as hole transporting material for organometal halide perovskite solar cells and achieved a power conversion efficiency of 6.6%.
Journal ArticleDOI
Tetra methyl substituted Cu(II) phthalocyanine as alternative hole transporting material for organometal halide perovskite solar cells
Georgia Sfyri,Challuri Vijay Kumar,Yulong Wang,Zong-Xiang Xu,Christoforos A. Krontiras,Panagiotis Lianos +5 more
TL;DR: In this article, methyl substitution facilitates closer molecular packing leading to a stronger extinction coefficient, stronger ϿϿ interaction and higher charge carrier mobility, and demonstrated improved performance with respect to unsubstituted copper phthalocyanine.
