Copper Indium Gallium Selenide (CIGS) and Cadmium Telluride (CdTe) are now used as p-type light absorbing layers in many commercially available heterojunction PV applications. When compared to conventional Crystalline Silicon solar cells, benefits include improved photoresponse in low light conditions, as well as compatibility with flexible substrates. However, due to the rarity of Indium and Tellurium, both CIGS and CdTe are expected to experience supply issues and increasing costs in the future. Kesterite Copper Zinc Tin Sulphide/Selenide (CZTS(Se)) is a non-toxic material containing only earth abundant elements, and is a promising candidate to act as an absorber layer in future large scale flexible PV applications. CZTS(Se) is proven to be solution processable and has a record power conversion efficiency of approximately 12%, and in pure selenide form has a bang gap of approximately 1.1eV. Perovskite based materials have achieved efficiencies of up to approximately 21% and are solution processable via simple deposition techniques. With a band gap of up to approximately 2.3eV, perovskites could be an ideal counterpart to CZTSe in a tandem solar cell. There is also potential for common materials to be used for other layers in both Perovskite and Kesterite solar cells, for example zinc oxide or metal sulphides, which further lends these materials to a hybrid device. An investigation into the manufacture of Perovskite-Kesterite hybrid cells is a possible route to efficient and flexible large scale PV.
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.
