OPV efficiency values are moving towards > 20 % for small area cells and > 15 % for large scale modules. With these performance values, OPV is reaching out to applications that are going beyond the typical niche markets. Integration of OPV into functional objects is attractive for building integrated / attached PV, window integrated PV, vehicle integrated PV, textile PV or agri-/horti PV. Most interestingly, all these application scenarios are related to flexibility and light weight. However, besides few demonstrations of ultra-flexible and foldable organic solar cells, the limitations of lightweight OPV that is compatible to mass production are not fully understood.
OPV devices require encapsulation by barrier films to reduce the degradation driven by extrinsic factors, which in turn limits their flexibility and leads to lower specific power values. In this talk, we analyze the packaging requirements for light weight cells and modules. Fully solution-processed and semitransparent organic solar cells performing comparable with conventional indium tin oxide-based devices are processed directly onto different barrier films of varying thicknesses. Direct cell fabrication onto barrier films leads to the elimination of the additional PET substrate and one of the two adhesive layers. In addition to the increase of the specific power to 0.38 W/g, which is more than four times higher than sandwich-encapsulated devices. These organic solar cells exhibit better flexibility and survive 5000 bending cycles with 4.5 mm bending radius, show comparable stability as conventionally encapsulated devices under constant illumination (1 sun) in ambient air for 1000 h. A further step to increase the W/g Figure of Merit is to replace the top laminated barrier by a printed barrier, reducing the weight by another factor of 2. In combination with high performance NFA based composites, these architectures have the potential to overcome the 1 W/gr milestone while still being compatible to roll to roll production.
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.
