Perovskite solar cells (PSC) have received a lot of interest as one of the most favourable emerging PV technology. The facile fabrication methods has made this technology favorable for commercial development. Recently, perovskite solar cells has achieved, the power conversion efficiency (PCE) reaching 25.6%.[1] This progress in perovskite PV technology is achieved via drastic research efforts in the domain of engineering of variety of layers in the solar cell stack. Electron transporting layer (ETL) is one of the most important layers, its modification, deposition, and optimization are the main challenges to be considered for high performance solar cells. The interface between ETL and perovskite active layer, plays a crucial role for the efficient extraction and transport of charges with minimum recombination losses between these layers.
In this work, we synthesis and characterization of a family of indene-C60 adducts obtained via Diels-Alder cycloaddition [4+2]. The new C60 derivatives include indenes with a variety of functional groups. This synthetic methodology provides a novel approach to obtain a wide spectrum of indene-fullerene adducts, which are inaccessible by previous conventional. We also performed computational simulations and CV measurements, the result of which indicates the LUMO energy levels are in the right place for these compounds. Therefore, these adducts were considered as electron transporting materials (ETMs) for planar heterojunction perovskite solar cells. Selected derivatives were applied into inverted (p-i-n configuration) perovskite device architectures, fabricated on flexible polymer substrates, with large active areas (1 cm2). One of them (6’-Acetamido-1′,4′-dihydro-naphtho[2′,3′:1,2][5,6]fullerene-C60 – NHAc-ICMA) showed power conversion efficiency (PCE) of 13.61%.

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.
