Among the 3rd generation thin film solar cells, Organic-Inorganic hybrid perovskite is a suitable low cost light harvesting layer to be used as a substitute of conventional ones to fabricate high efficiency photovoltaic (PV) cells. Such materials have the desired electronic and optical properties for PV applications, such as direct band gap, high absorption coefficient, high carrier mobility, and longer diffusion length. In this work, perovskite PV cells with the structure, FTO/Compact-TiO2(50 nm)/Meso-TiO2(150 nm)/Methylammonium lead tri-iodide(300 nm)/Spiro-OMETAD(200 nm)/Au (100 nm), were fabricated. The perovskite film was prepared using one step solution process. TiO2 and Spiro-OMETAD are the electron transport material and hole transport material, respectively. Aforementioned solar cell structure reached up to maximum 16.51% efficiency (Voc = 1.095V, Jsc = 20.580mA/cm2, and fill factor = 71.7%). The performance of the cell is governed by the charge transport and recombination in the absorbing material but also by the charge extraction at the ETM/Perovskite and HTM/perovskite interfaces. Charge transfer dynamics in perovskite based samples with different HTM layers was explored using photo-luminescence (PL) technique. The obtained experimental results provide valuable indications for the design of highly efficient Organic-Inorganic perovskite PV 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.
