“…Another interesting HTL is low-cost copper phthalocyanine (CuPc) since CuPc has a narrow band gap and shows good operational device stability. , The device structure based on the conventional assembly using the CuPc nanorods as HTM and carbon as an electrode layer demonstrated the best PCE of 16.1% . These properties make CuPc more likely to be compatible with CuSCN in the HTL layer for PSC fabrication.…”

Perovskite solar cells (PSCs) are an innovative technology with great potential to offer cost-effective and high-performance devices for converting light into electricity that can be used for both outdoor and indoor applications. In this study, a novel hole-transporting layer (HTL) was created by mixing copper phthalocyanine (CuPc) molecules into a copper(I) thiocyanate (CuSCN) film and was applied to carbon-based PSCs with cesium/formamidinium (Cs0.17FA0.83Pb(I0.83Br0.17)3) as a photoabsorber. At the optimum concentration, a high power conversion efficiency (PCE) of 15.01% was achieved under AM1.5G test conditions, and 32.1% PCE was acquired under low-light 1000 lux conditions. It was discovered that the mixed CuPc:CuSCN HTL helps reduce trap density and improve the perovskite/HTL interface as well as the HTL/carbon interface. Moreover, the PSCs based on the mixed CuPc:CuSCN HTL provided better stability over 1 year due to the hydrophobicity of CuPc material. In addition, thermal stability was tested at 85 °C and the devices achieved an average efficiency drop of approximately 50% of the initial PCE value after 1000 h. UV light stability was also examined, and the results revealed that the average efficiency drop of 40% of the initial value for 70 min of exposure was observed. The work presented here represents an important step toward the practical implementation of the PSC as it paves the way for the development of cost-effective, stable, yet high-performance PSCs for both outdoor and indoor applications.

“…The high mobility of charge carriers and the efficiency of light energy conversion allow us to consider metal phthalocyanines as promising materials for photovoltaic cells [3]. One of the effective ways to increase the optical sensitivity range and improve the photoelectric characteristics is the formation of nanocomposite structures of metal phthalocyanine complexes.…”

The role of spin states in the process of charge carrier transport in copper phthalocyanine (CuPc) nanowires has been established. According to the data obtained, CuPc nanowires are in the η-phase. The current-voltage characteristics (IVC) of a photosensitive cell based on CuPc nanowires in a magnetic field are investigated. As a result of experiments, it was found that applying an external magnetic field, the spins of two positively charged polarons are oriented in one direction. The channel of formation of the bipolaron is blocked. As a result, a decrease in the short-circuit current of the photosensitive cell is observed by more than 61%.

The paper presents results of a study of photo-electrophysical characteristics in a solid film and nanowires of cobalt phthalocyanine (CoPc). A solid CoPc film on a substrate with a conductive surface ITO (indium tin oxide) was obtained by thermal evaporation in vacuum. CoPc nanowires were obtained by the temperature gradient physical vapor deposition (TG-PVD). Measurements of current-voltage characteristics were carried out using a potentiostat-galvanostat P20X in the linear sweep mode. The study of transport kinetics and carrier recombination was carried out on the impedance meter P45X. A xenon lamp with radiation intensity equal to 100 mW/cm 2 was used as a solar light simulator.
