Organic-inorganic perovskite solar cells (PSCs) have been showing huge potential in new photovoltaic technology due to their excellent optoelectronic properties. However, water sensitivity of these devices has become an urgent issue to be solved. Packaging is one of the most important tools to improve perovskite solar cell device stability. Benefiting from good chemical stability and transparency, polydimethylsiloxane (PDMS) has been widely used in fabrication processes for microfluidic and electronic devices. In this work, we propose a facile and efficient passivation way applying hydrophobic fluoropolymer (CYTOP) and PDMS. CYTOP was spin-coated on the surface of devices at 80 ℃ and PDMS was annealed at 75 ℃. Thus, CYTOP and PDMS form a compact and removable package for the solar cells. To evaluate the influence of the barriers in cells toward harsh environment, we exposed the packaged ones to de-ionized water. Combining with the top glass sheet, the waterproof ability of the PSCs is characterized by the photovoltaic performance degradation after exposed to water. It is found that the open circuit voltage and short-circuit current density of packaged cells only suffer 33% loss for both through a 10 hours de-ionized water-soaking. Such a feasible method unlocks a kind of valuable route for protecting the perovskite solar cells from harsh moist environment.
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.
