Perovskite solar cells (PSCs) are highly printable, enabling large-volume production that is necessary to rapidly introduce this new technology to the market and help combat climate change . Flexible PSCs are typically deposited on synthetic polymer substrates such as PET and PEN—materials that suffer from poor gas barrier properties and low thermal stability [2], and whose fossil-based origin makes incineration for PSC recycling problematic. Cellulose, the backbone of paper and cotton, is a bio-based alternative to synthetic substrates, as it can form flexible and transparent films suitable for printed electronics [3]. Here, I show how cellulose can be crosslinked to improve solvent resistance [4] and how new electrode materials can be used to achieve low surface roughness while maintaining high conductivity and transparency [5], among other improvements. Transitioning to a bio-based substrate requires a combined effort from both the cellulose and perovskite communities. As we push for increased sustainability, the perovskite fabrication process must be adapted to use greener solvents [6], low-temperature deposition methods [], and more sustainable encapsulation materials []. We believe that this strategy can improve PSC recyclability and further advance the technology toward a more circular economy.
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.
