Despite tremendous efforts to enhance the performance of polymer- and perovskite-based solar cells (PSCs and PeSCs), considerable energy loss is still caused by the non-radiative recombination of charges or charge-transfer excitons as a result of trapping sites and insufficient internal electric fields (Ein). Thus, a strong Ein across the photoactive layer is required for efficient charge extraction at each electrode. Here, we report a universal method of ensuring a larger Ein in both PSCs and PeSCs through the incorporation of a pair of strong electric dipole layers (EDLs) based on conjugated polyelectrolytes for both anode and cathode. The Ein that develops between the EDLs is significantly intensified, and the sweep-out time of the photo-generated charges is shortened by ~ 50%. Our approach is generally applicable to various donor polymers and perovskite systems, and it results in an enhancement of the power conversion efficiencies (PCEs) of both PSCs and PeSCs by > 15% compared with conventional devices using typical charge transport layers (CTLs) such as metal oxides and/or conducting polymers.
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.
