Proceedings of 6th International Conference on Hybrid and Organic Photovoltaics (HOPV14)
Publication date: 1st March 2014
The environmental stability and lifetime of photovoltaic devices is a prime concern, particularly in the research of novel photovoltaic technologies. Organic, hybrid and Perovskite-based photovoltaic devices have all previously exhibited poor stability in oxygen rich and humid environments, with significant reduction in power conversion efficiencies observed, particularly when combined with light exposure. The National Physical Laboratory has a state-of-the-art experimental stability testing rig which can control the H2O and O2 content within a sample chamber to the part-per-million level in an arrangement that allows the continuous electronic or spectroscopic investigation of device properties. In addition, the exposure to illumination and temperature can also be controlled, allowing the study of the degradation of solar cells in detail and under highly controlled conditions. The precision H2O and O2 controls present many advantages, such as allowing the comparison of device degradation under pure-N2 conditions, as well as conditions similar to those within an encapsulated device, ambient conditions and everything in between.
The latest experimental results on the stability of polymer:fullerene photovoltaic devices in this novel environmental testing system will be presented. In OPV devices, interlayers between the active material and electrodes have previously been shown to degrade faster than the photovoltaic material itself, particularly the commonly used material poly(3,4-ethylenedioxythiophene) poly(styrenesulfonate) (PEDOT:PSS). Here we present the results of a systematic study of devices with various interlayers, with the aim of isolating and identifying degradation of specific interlayer materials in both encapsulated and ambient conditions. This includes time-dependent electrical, optical and chemical measurements of OPV devices throughout the degradation process to identify the main modes of failure.
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.
