Organometal trihalide perovskite (CH3NH3PbI3) solar cells have reached to over 20% power conversion efficiency (PCE). The cost-effective solution process has attracted the scientific and industrial interests. However, perovskite solar cells are quite unstable. At first, the CH3NH3PbI3 crystal is a moisture sensitive material to be decomposed as CH3NH2, HI and PbI2. Second, the CH3NH3PbI3 perovskite solar cells can be deteriorated under light without sealing in one day. The CH3NH3PbI3 crystal can be decomposed to PbI2 effectively with the presence of three elements: TiO2, light and moisture. In our study, perovskite solar cells have been fabricated in porous three layers as, <glass/F-doped tin oxide (FTO)/dense TiO2/porous TiO2-perovskite/porous ZrO2-perovskite/porous carbon-perovskite>. The porous carbon layer can work as the back contact. Stability tests of the perovskite solar cells were managed against light (Vis or UV-Vis) and heat (room temperature to 120 ËšC). Without sealing, the perovskite solar cells using porous carbon electrodes became stable significantly under AM 1.5 (100 mW cm-2) over 100 h. The details of results about XRD, XPS, impedance measurements will be opened in the conference.
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.
