Metal halide perovskite solar cells have gained tremendous attention due to their high power conversion efficiencies and potential for low‐cost manufacturing. Their wide and tunable bandgap makes perovskites ideal candidates for tandem solar cells with narrow bandgap photovoltaic technologies, such as crystalline silicon, Cu(In,Ga)Se2, and low-bandgap perovskite, to go beyond the efficiency beyond the Shockley–Queisser single-junction limit. The past 5 years have witnessed unprecedented advancements in perovskite-based tandems, with lab-scale devices (up to around 1cm2) approaching or even surpassing efficiency records of their single-junction building blocks. Currently, the majority of the perovskite-based tandems are fabricated on rigid glass substrates. It is highly desirable to develop perovskite tandem solar cells on flexible and lightweight substrates. This would open up the possibilities for high throughput roll-to-roll manufacturing and various attractive applications including the portable and wearable electronics, smart buildings, transportations, etc., where a combination of high efficiency, lightweight, and flexibility are important considerations. In this contribution, we will present our progress on developing highly efficient flexible wide-bandgap perovskite solar cells with high near-infrared transmittance and flexible narrow-bandgap CIGS and Pb-Sn perovskite solar cells. We demonstrate over 22% and 24% in all-perovskite and perovskite-CIGS flexible thin film tandems, respectively.
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.
