Textured interfaces have demonstrated to be an effective strategy to enhance light harvesting in solar devices. Different texture schemes applied to the many types of solar cell technologies have been reported over the years, demonstrating their potential as light trapping structures. Nevertheless, the effect of a particular texture design may not be restricted to enhance light absorption, but also to induce favorable conditions for the fabrication, performance and stability of the subsequent layers in the device. Consequently, in certain solar cell technologies, a textured device may outperform the planar configuration due to the combination of several factors.
During the talk, different texture arrays applied to either rigid or flexible substrates will be analyzed along with their effect in the perovskite-based solar cells performance. Moreover, some of such arrays were applied to multi-junction configurations such as Si-perovskite or all-perovskite tandem devices, expanding their application beyond standard single-junction devices. Apart from the expected increase in the current delivered by the device, some textures also enhanced other properties such as wettability, perovskite growth or bending performance. Finally, the unification of certain textures to induce hierarchal arrangements will be discussed as a technique to retain the benefits from more than one texture configuration.
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.
