Proceedings of International Conference on Hybrid and Organic Photovoltaics (HOPV16)
Publication date: 28th March 2016
The center of research field of emerging photovoltaics has been moved to perovskite solar cells with the highly favorable characteristics such as high absorption coefficient, long range exciton diffusion length and low temperature fabrication process. The power conversion efficiency was already achieved above 20% under 1 sun illumination. However, most high efficiency devices are based on high temperature processed oxide layers. Even, perovskite solar cells show huge hysteresis without mesoporous oxide layer. Moreover, the weakness to humidity of perovskite layer accelerates the life time decay of the device. In this study, we fabricated low temperature processed inverted perovskite solar cells based on PEDOT:PSS [poly(3,4-ethylenedioxythiophene) polystyrene sulfonate]. We investigated the effect of inserting electron injection layer Liq [8-hydroxyquinolatolithium] between PCBM [[6,6]-phenyl-C61-butyric acid methyl ester] and silver electrode. As a result, we got improved photovoltaic performance compared to the control device, especially on fill factor and the stability. The hysteresis free perovskite solar cells are shown with the physical analysis such as light intensity dependent investigation and optical analysis such as conductive atomic force microscopy and photoluminescence.
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.
