High efficiencies of more than 23% had been achieved in the tin-lead (SnPb) perovskite solar cells (PSCs) incentivized researchers to further explore and improve their performance and also stabilities. However, the SnPb PSCs are not quite reliable and at disadvantages when competing with other forms of solar cells due to their stability issues. In this study, we compared few options of carrier selective layers and their structures in an inverted single junction perovskite solar cell configuration. A proper selection of carrier selective layers allows us to restructure the PSCs in order to correct the energy alignment in solar cell devices for effective carrier extractions, reduced interfacial recombination and also promote a barrier for ions migration, thus enhanced the performance efficiency and their stabilities. High efficiency of >22% along with high photo and thermal stabilities were demonstrated when the above strategies were adopted. The SnPb PSCs which was stored in the nitrogen filled air are able to retain more than 99% of their efficiencies after 1 month of storage in dark, under nitrogen air. In term of thermal stability, the PSCs are able to retain >90% of their initial efficiencies after subjected to the temperature of 85 °C for over 1000 hours in nitrogen atmosphere. Our exploratory of the successful treatment of the doping and structuring strategies was followed with series of investigations which includes the morphological, structural and elemental assessment of the SnPb thin films before and after exposure to thermal heating via SEM, XRD and XPS. We will also demonstrate the effects of doping and structuring strategies via impedance spectroscopy experiment. Our research concludes that the most important factor that prevent the degradation in the SnPb PSCs underlies in the physical barrier that can restrict the ions migration. This valuable knowledge could help us in the fabrication of the SnPb PSCs with high efficiency and excellent performance stabilities.
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.
