Emerging photovoltaic (PV) technologies are being developed to improve the performance and the stability of solar cells. The objective of this work is the assembly of two types of light harvester materials (perovskite and quantum dots (QDs)) forming a heterojunction to obtain devices with good PV activity and stability enhancement at ultraviolet (UV) region [1], [2]. First, solar cells based on perovskite as active layer were fabricated and characterized, taking into account the challenge to work in ambient atmosphere (no glove box) to be close to an industrial process. Two types of PV devices (drop casted and spin coated) were prepared using a simple MAPbI3 with 5-Ammonium valeric acid iodide (AVAI) additive and a mixed halide perovskite MAPbI3−xClx. The resulting maximum power conversion efficiencies (PCE) of the devices were 10.7 % and 12.9 % for drop casted and spin coated cells, respectively. Afterwards, the research continued with the synthesis and characterization of CsPbBr3 quantum dots and their incorporation into PV devices in combination with perovskite. The performance obtained by coupling QDs with perovskite was better than perovskite alone only for drop casted devices with an absolute PCE increase of 5.6 %. To further investigate the stability of these devices, aging campaigns at damp heat conditions and light exposure will be conducted. Dedicated characterizations techniques will be used for the study and analysis of layer modifications due to degradation.
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.
