World energy consumption has been gradually increasing past 50 years and limited sources of fossil fuels are exacting the research on sustainable and renewable energy resources. The conversion of sunlight into electricity is one of the most attractive alternatives for increasing energy demands. Photovoltaic systems could potentially be future electricity generation source with significantly reduced negative impact on environment. [1] Due to simple manufacturing and good performance prospects perovskite solar cells received growing interest from research community. As a result of rapid development in this field, perovskite photovoltaic systems have reached efficiency of 23.7% [2].
Despite relatively high performance of perovskite solar cell (PSC), the current conditions still do not meet the requirement for commercialization. There are three main stability issues with PSCs: environmental (moisture and oxygen), photo and thermal stability. In addition, selective contacts and additives in HTM can also have influence on stability [3,4] .
Charge-transporting materials has been developed for use in perovskite solar cells and vast majority of them require the use of chemical doping as an essential step for preparation of efficient devices. Oxidized 2,2´,7,7´-tetrakis(N,N-di-p-methoxyphenylamine)-9-9´-spirobifluorene (Spiro-MeOTAD) could be one of the potential weak links in the perovskite solar cell composition. Interestingly, very little investigation is done concerning the oxidized HTMs applied in the PSC and their roperties.[3]
In this work oxidized spiro-OMeTAD, have been investigated under various conditions in order to estimate influence of temperature, different additives and ion migration from perovskite surface on stability of oxidized spiro-OMeTAD.
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.
