Tin-based perovskite solar cells (lead-free tin perovskite solar cells and tin-lead alloyed perovskite solar cells) follow the lead perovskite solar cell. The research trends of these tin-based perovskite solar cell are reviewed. The efficiency of the lead-free tin perovskite solar cells and that of tin-lead alloyed provskite soalr cells are over 15-16% and 23-24%, respectively. By suppressing the Sn4+ concentration, decreasing the defect density by the surface passivation, decreasing the band-offset of the conduction bands and the balence bands, relaxing the lattice strain and so on, these efficiencies have been enhanced. We have reported 15.3% efficiency of lead-free tin perovskie solar cells and 23.3% efficiency of tin-lead alloyed perovskite solar cells by using Ge 2+ addition, the passivation with ethylene diamine, the direct deposition of tin-metal, the incorporation of inorganic layers, the introduction of spike band structure and mixed SAM, and A site engineering relaxing the lattice strain1,2). The interface between the tin perovskite layer and these inorganic nanoparticles are discussed from the view point of charge transfers increasing carrier densities under dark and decreasing photovoltaic performances3). Thermal stability of the thin-lead alloyed perovskite solar cells (85 ℃, 1000 h) was improved by covering the grain-boundary with GeOx and inserting the SnOx layers in the electron transporting layer4). The importance of the position of inserting ALD SnOx is discussed, together with modified electron-transporting layer enhanceing the thermal stability. All-perovskite tandem solar cells are composed of the wide bandgap lead-perovskite solar cells, the narrow bandgap tin-lead alloyed perovskite solar cells and the interconnecting layer. The efficiency of all-perovskite solar cells is now over 30%. We have reported 26-27% efficiency5, 6). The research focused on the interconnecting layer for enhancing the efficiency are reviewed.
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.
