Solution-processed bulk heterojunction (BHJ) polymer solar cells (PSCs) have exhibited great potentials for making large area and flexible solar panels through low-cost solution coating techniques. Typically, a BHJ active layer in a PSC is composed of a conjugated polymer as electron donor and an organic compound as electron acceptor. In recent years, the applications of non-fullerene-based small molecular acceptors materials have afforded great opportunities to achieve higher power conversion efficiency (PCE) in PSCs. In comparison with the PSCs based on fullerene-based acceptors like PCBM, photovoltaic performance of the fullerene-free PSCs are even more sensitive to the intrinsic properties of the polymer donors and non-fullerene acceptors in their active layers. In the past year, our group focused on the study of material design for fullerene-free PSCs and achieved a series of high performance PSCs. Based on these studies, we suggested a few feasible methods for molecular design of the donors and the acceptors and also tried to correlate the molecular energy levels, aggregation morphologies and other intrinsic properties of the active layer materials with their photovoltaic behaviors in device. Furthermore, we used the polymer donors and small molecular acceptors with the optimized chemical structures to construct a single-junction and double-junction tandem PSC with PCEs over 14%.
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.
