Proceedings of International Conference on Hybrid and Organic Photovoltaics (HOPV16)
Publication date: 28th March 2016
In recent years, organic–inorganic halide perovskites have become increasingly popular and promising as photovoltaic materials for third-generation solar cells. The electron-selective layer (ESL), one of the most important components in highly efficient PSCs, is responsible for the extraction of the photogenerated electrons and simultaneously serves as a blocking layer to prohibit the direct contact of the conductive substrate with the hole-transport material (HTM) and the metal cathode. The strategies established for the low-temperature fabrication of inorganic ESLs are generally based on nanocrystallites that guarantee the desired electronic properties of ESLs. As we know, it is very facile to obtain amorphous inorganic materials at very low temperatures; however, amorphous inorganic ESLs for PSCs have been rarely reported up to now.WOx, SnO2, and ZnO are common oxide semiconductors with high electron mobility and other special electronic properties. Our group studied these three kinds of ESLs material for PSCs. We will report our recent results, especially, about the one facile solution route to successfully fabricate inorganic, amorphous WOx-based composite ESLs at the very low temperature of 70 °C and at room temperature for efficient planar PSCs. The flexible PSCs generated a high PCE of 11%. More inspiringly, the rigid PSCs using the ESL that were prepared at 25 °C, also achieved PCEs exceeding 14.0%.

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.
