Perovskite single crystal shows more advantages in nature compare to polycrystalline perovskite, such as higher charge carrier mobility, lower trap density and longer carrier diffusion lengths than polycrystalline perovskite. However, the area of perovskite single crystal on HTL(hole transporting layer)-coating ITO (indium tin oxide) substrate is not fully covered as the polycrystalline perovskite solar cell process does. Therefore, we develop a new pathway to increase perovskite single crystal area on HTL-coating ITO substrate by using polypropylene (PP) as an upper covering plate during the growth of perovskite single crystal. The average ratio between perovskite single crystal area and HTL-coating ITO substrate by using PP is 52.7%, while the average ratio by using same HTL-coating ITO substrate as an upper covering plate is 24.99%. Besides, we use oxygen-argon plasma treatment to change the contact angle of ITO glass instead of UV-ozone treatment to reduce process time. The contact angle of HTL-coating ITO glass decreases rapidly from 71.79 to 62.97 only takes 10 sec for oxygen-argon plasma treatment on ITO glass, while UV-ozone treatment needs a few minutes to reach the same contact angle. The results show 30 sec oxygen-argon plasma treatment can reduce the process time and gain maximum area of perovskite single crystal at the same time. Eventually, we successfully fabricated a perovskite single-crystal solar cell, the short-circuit current density (Jsc), open-circuit voltage (Voc), and fill factor (FF) are 15.3 mA/cm2, 0.69 V, and 43.25 %, respectively, yielding a power conversion efficiency (PCE) of 4.54 %.
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.
