In p-i-n structured perovskite solar cells (PSCs), C60 material is widely employed as the electron transport material (ETM). However, due to the relatively weak adhesion between C60 and perovskite, the bonding is susceptible to disruption by external impacts, ultimately resulting in stability degradation issues. Herein we introduce naphthalene diimide derivative (NDI-D) as an C60 bonding layer in PSC. NDI-D material is a planar structure composed of pi-conjugation, allowing for some pi-pi stacking and van der Waals interactions with C60. We have not only ensured structural stability using NDI-D, which incorporates functional groups capable of interacting with perovskite, but also improved the electrical performance of the device. We found that strong adhesion with NDI-D between perovskite and C60 and lifetime of electrons is increased compared to the pristine device. The perovskite solar cell characteristics were observed through techniques such as PL (photoluminescence), TRPL (time-resolved photoluminescence), UPS (ultraviolet photoelectron spectroscopy) and SEM (scanning electron microscopy).
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.
