The current R&Ds of perovskite solar cells (PSCs) has created many unique methods in molecular engineering, using organic molecules, for defect passivation at grain boundaries and heterojunction interfaces in PSCs.1 Our group has focused on the method of interfacial passivation with functional organic molecules, which enables high voltage output (close to theoretical limit) in photovoltaic performance.2 For practical applications, the stability of the devices still remains a major challenge. Organic cations in halide perovskites and diffusible dopants in hole transport materials (HTMs) are responsible for low stability at high temperatures (>120oC). To solve this, all-inorganic compositions of perovskite and use of dopant-free HTMs are highly desired. CsPbI2Br PSCs (bandgap 1.9eV) achieved high Voc over 1.4V with PCEs of >17%. Under indoor LED illumination, it works at PCE >34% being supported by high Voc.3 Passivation of iodine defects with 2,5-thiophenedicarboxylic acid (TDCA) achieved Voc of 1.54V for CsPbIB2.4 As inorganic perovskites, lead-free compositions such as Ag-Bi halides also become an important target for achieving environmentally kind PSCs.5 AgBiS2 as a sulfur-based IR-absorbing material achieves high photocurrent densities (>34mA/cm2).6
For implementation of PCSs in society, lightweight modules are demanded. Thin plastic film-based PCSs are manufactured by low-temperature material preparation.7 Ink-jet coating process is applicable for device fabrication. This topic will also be introduced in the lecture.
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.
