Hysteretic behavior is one of the characteristic challenges of perovskite solar cells. It is assumed to be a combined effect of bulk defect properties (ion migration) and optimized contact layers. The traditional TiOx planar layer used for standard architectures is more and more believed to be critical for hysteresis-free behavior and needs a high-temperature annealing procedure.
One newly discussed alternative approach is the use of CdS for interlayers as which is also well-known as buffer for Cu(In,Ga)Se2 solar cells. Its energetic band structure suites well with MAPbI3 and it is easily processible at low temperatures by chemical bath deposition (CBD). The process is also proven to be scalable to square meter sizes.
We hence investigate different series of CdS directly on ITO or FTO with different thicknesses and composition, using also ZnS-CdS mixtures. Additionally the combination of CdS with further stacked electron conductive layers (TiOx, PCBM) is surveyed. It shows out that indeed the hysteretic behavior can strongly be improved by the use of CdS interlayers with nearly no hysteresis after an initial light-bias. Hence efficiencies of up to 10 % are achievable by a generally simple and cheap low-temperature process based on CBD and spin-coating.
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.
