The efficiency of lead perovskite solar cells (Pb-PVK-PV) has now exceeded 26%. Tandem cells consisting of Pb-PVK-PV as the top cell and Si solar cell as the bottom cell have attracted much attention as solar cells with higher efficiency than Pb-PVK-PV. The certified efficiency has now reached 32.5%. In addition, especially from the perspective of flexible tandem solar cells, all-perovskite tandem solar cells have advantages over tandem cells consisting of Pb-PVK-PV (top)/inorganic solar cell (bottom) because both the top and bottom cells are manufactured using a low-temperature printing process. The efficiency of all-perovskite tandem solar cells is reported to be 28%. However, the toxicity of Pb has long been criticized, and for this reason, people have developed various Pb substitutes: Sn, Ge, etc. Among them, Sn-based perovskite solar cells have developed rapidly and have now exceeded 15%. Since it is very difficult to further improve the efficiency of single-cell Sn-based perovskite solar cells, in order to further manufacture non-toxic perovskite solar cells, we need to develop new device structures. Our research focuses on the efficiency breakthrough of wide-bandgap Sn-based perovskite solar cells. This is to prepare for our subsequent GIGS/Sn-PVK tandem cells. In order to further improve the efficiency of wide-bandgap solar cells, we introduced ferrocene derivatives at the PEDOT:PSS/PVK interface. By repeatedly optimizing the concentration of the modifier, we successfully increased the efficiency of the WBG Sn PSC to more than 11%. At the same time, we successfully prepared a CIGS/WBG-Sn-PVK tandem solar cell with an efficiency of more than 14%. This is the world's first report on all-lead-free perovskite tandem solar cells, and it also provides guidance and help for further improving the efficiency of Sn-based solar cells.
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.
