Achieving a relatively high power-to-conversion efficiency (PCE) in all-polymer solar cells remains a significant challenge. Precisely controlling the phase separation between polymers to attain an ideal film morphology is a topic that requires in-depth exploration. Numerous studies have found that optimization through various processes, including the choice of porcessing solution, the use of additives, the method of film deposition, and the control of film thermal annealing procedures, can enhance device performance. In this work, it will focus on the selection of different porcessing solutions and the use of additives to regulate film morphology. By employing these two methods to control the film morphology and further improve the miscibility between polymers leads to a tighter and more regular polymer packing. Benefitting from the ideal film morphology, it facilitates efficient charge separation and conduction, reducing unnecessary charge carrier losses, and ultimately enhancing the overall efficiency. In this work, we introduce a strategy involving the use of a mixed solution. In addition to the original chloroform precursor solution, a high-boiling-point green solution have been incorporated. The addition of the high-boiling-point solution alters the overall volatility of the solution, thereby influencing the solution-to-film forming rate. This also leads to changes in the polymer domain size within the active layer. In addition to employing the aforementioned strategy, we have also added the common volatile solid additive DTT to polymer solution. In this work, we use a more efficient all-polymer blend system, PM6:PY-IT. The PM6:PY-IT devices based on all mixed solvent systems deliver a very high PCE of >17%.
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.
