Proceedings of 6th International Conference on Hybrid and Organic Photovoltaics (HOPV14)
Publication date: 1st March 2014
In the frame of European research project “Energy for a Green Society” (ERG project) are being developed novel solar cells (energy harvesting) for different classes of applications, from rooftop to microscale. One of these novel solar cells are printable Dye Sensitized Solar Cells (DSSC) and the demonstration of the commercial viability represents one of the project’s key objectives. The existing standards tests for photovoltaic technologies (PV) are intended to evaluate stability for outdoor applications. But, the growth of the market for solar cells to power wireless sensors and portable electronic devices for wide range of applications has necessitated the design of standard reliable tests to evaluate the stability and performance of PV for different applications. So, here it is presented an aging test designed to evaluate the stability of DSSC as power supply in low temperature ambient, as fridges, Nordic Countries, etc. The test is based on three different aging: storage at -20ºC; storage at 0ºC under a 0.5V bias and up to 100 thermal cycles from -20ºC to 70ºC. The electrical parameters of the modules have been characterized under 200Lux before and after the aging test to evaluate the stability of this DSSC under these conditions. Results indicate that DSSC are stables in the three aging conditions because the power of DSSC does not decay more that 9 %. Hence these results suggest that this type of DSSC produced by SolarPrint can be used at low temperature environments as energy supply devices.
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.
