The introduction of self-assembled monolayer (SAM) hole transporting materials (HTMs) made a significant contribution towards development of p-i-n architecture perovskite solar cells (PSCs). Carbazole-based derivative V1036 was one of the first SAM HTMs to be successfully used instead of standard PTAA. Although it demonstrated slightly lower efficiency (17.8 %) compared to PTAA (19.2 %), it was evident that monolayer can be efficient compared to the polymeric films of regular thickness [1]. Not long after, V1036 structure was optimized, simplified and its analogues 2PACz and MeO-2PACz were introduced. These small but important structural changes resulted in an increase in p-i-n PSC performance, as 2PACz and MeO-2PACz exhibited PCEs of 20.8 % and 20.2 % respectively, higher than that of PTAA (18.9 %) [2]. Combined with conformal coverage, minimal parasitic absorption and material consumption, SAM HTMs became an important research subject for optoelectronic applications, such as organic photovoltaics, perovskite/silicon tandems or organic light-emitting diodes [3-5]. In this research, new SAM HTMs were synthesized and investigated as 2PACz alternatives to further broaden the scope of possible applications. Two main strategies for structural modifications were applied: selection of different chromophores and incorporation of different functional groups. New SAM materials have been successfully used to construct devices such as p-i-n PSCs, bulk heterojunction organic photovoltaics, organic light-emitting diodes and sensors.
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.
