With respect to conventional photovoltaic technologies hybrid and organic photovoltaics (HOPV) have revealed significant advantages in terms of materials, fabrication process and applications. HOPVs enable a full customization of the photo-active area of the devices that allows for achieving aesthetical requirements partially disregarded by traditional PV technologies. Due to the potential low cost of materials and fabrication process, Dye Solar Cell technology is considered the best candidates for the innovative application scenarios such as BIPVs (Building Integrated PhotoVoltaics). In this direction Dyepower a R&D Consortium founded by ERG Renew, Permasteelisa, and the Universities of Rome “Tor Vergata”, Turin and Ferrara, has been established with the aim of industrializing the DSC technology for BIPV applications, through the development of a pilot line for the production of photovoltaic glass façades. In this work we will present the effort made by Dyepower researchers to finalize the production process for large area devices and the results obtained in terms of the stability tests.

In particular we will show:

Pilot line production of glass-glass DSC module with 20x30 size
Optimal sealing technologies developed for DSC modules, in order to ensure at the same time the stability of the module and color uniformity over the entire device;
Assessment of the stability of large area (> 500 cm²) DSC modules through IEC 61646 standard test such as UV preconditioning, Humidity Freeze and Damp Heat.
Automatized fabrication of large area panels (>0,4 m²)
A cold lamination process developed for light weight and transparent DSC strings for BIPV applications;

a) UV stress test of Large area module; b) Humidity-Freeze test (10 cycles) of large area module; c)0.4 sqm DSC laminated panel

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.

MATSUS

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.

International Conference on Perovskite Thin Film Photovoltaics Perovskite Photonics and Optoelectronics

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.
