Development of new charge transporting materials used for solar cells construction is necessary to reach high performances. So far, new p-type semiconductor self-assembled molecules (SAMs) are being rapidly investigated [1], the effort devoted towards designing new n-type semiconductors is significantly less noticeable. This comes due to relative scarcity of suitable and available acceptors, used for non-fullerene ETMs synthesis [2]. The field of n-type semiconductors is dominated by C60 and its functionalized derivatives (e.g., PC61BM, PC71BM) in various structure of solar cells [3-5]. Nevertheless, difficult synthesis and purification, significant product cost of modified compounds (especially C70 derivatives) and a low solubility of non-modified fullerenes in organic solvents hinders their applicability in devices [3]. Moreover, fullerenes have limited variation of energy levels alignment, photochemical and thermal instability and relatively weak intermolecular interactions in the solid state, which is also important parameters for high performance solar cell [3-5].
In this work new n-type semiconductors containing naphthalene diimide, naphthalimides, fluorene and fluorenone central fragment along with various anchoring groups were synthesized and investigated for possible application in various structure of solar cell. These semiconductors demonstrated good thermal stability and suitable electrochemical properties for effective electron transport from absorber layer to cathode. SAMs have shown changed substrate contact angle, which indicates bond formation between monolayer forming compounds and perovskite, ITO, TiO2, Sb2S3, or Sb2Se3 surface.
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.
