For perovskite solar cells, one of the most efficient device architectures explored is n-i-p type structure in which HTL plays a significant role to achieve both long-term stability and enhanced performance. In the literature, there are lots of papers relating to new hole-transporting materials that have potentials to replace the most used spiro-OMeTAD. A wide number of HTMs including inorganic, polymer, metal organic compounds and small organic molecule HTMs have been synthesized and investigated. Among these materials, phthalocyanine stand out for its excellent optical property as well as their high mobility and thermal stability. The performance of phthalocyanine is associated with its thin film properties as HTL. Especially molecular aggregation in solvents causes solubility problem and poor device results. To overcome these drawbacks, large steric hindrance units were introduced at the peripheral sites of MPc (Zn or Cu), which suppress the molecular aggregation and improve utilization of solution-processing. In our work, 4,5-bis((2,4-dichorophenly)thio) phthalonitrile was used to synthesis of MPcs. Functionalized MPcs had good optical and thermal properties to be used as HTM. After the MPc concentration was optimized, cell performance of corresponding MPc HTL-based PSC compared with the spiro-OMeTAD based HTL.

nanoGe is a prestigious brand of successful science conferences that are developed along the year in different areas of the world since 2009. Our worldwide conferences cover cutting-edge materials topics like perovskite solar cells, photovoltaics, optoelectronics, solar fuel conversion, surface science, catalysis and two-dimensional materials, among many others.
Previously nanoGe Spring Meeting (NSM) and nanoGe Fall Meeting (NFM), MATSUS is a multiple symposia conference focused on a broad set of topics of advanced materials preparation, their fundamental properties, and their applications, in fields such as renewable energy, photovoltaics, lighting, semiconductor quantum dots, 2-D materials synthesis, charge carriers dynamics, microscopy and spectroscopy semiconductors fundamentals, etc.
International Conference on Hybrid and Organic Photovoltaics
International Conference on Hybrid and Organic Photovoltaics (HOPV) is celebrated yearly in May. The main topics are the development, function and modeling of materials and devices for hybrid and organic solar cells. The field is now dominated by perovskite solar cells but also other hybrid technologies, as organic solar cells, quantum dot solar cells, and dye-sensitized solar cells and their integration into devices for photoelectrochemical solar fuel production.
Asia-Pacific International Conference on Perovskite, Organic Photovoltaics and Optoelectronics
The main topics of the Asia-Pacific International Conference on Perovskite, Organic Photovoltaics and Optoelectronics (IPEROP) are discussed every year in Asia-Pacific for gathering the recent advances in the fields of material preparation, modeling and fabrication of perovskite and hybrid and organic materials. Photovoltaic devices are analyzed from fundamental physics and materials properties to a broad set of applications. The conference also covers the developments of perovskite optoelectronics, including light-emitting diodes, lasers, optical devices, nanophotonics, nonlinear optical properties, colloidal nanostructures, photophysics and light-matter coupling.
The International Conference on Perovskite Thin Film Photovoltaics Perovskite Photonics and Optoelectronics (NIPHO) is the best place to hear the latest developments in perovskite solar cells as well as on recent advances in the fields of perovskite light-emitting diodes, lasers, optical devices, nanophotonics, nonlinear optical properties, colloidal nanostructures, photophysics and light-matter coupling.
