The efficiency and stability of halide perovskite solar cells (PSCs) are sensitively altered by the chemical modification of junction interfaces. MXene, as a physically robust and conductive nanosheet, can replace organic charge transport materials. MXene modifying the surface of NiOx layer serves as an inorganic and thermally stable hole transport layer (HTL). A p-i-n type PSC composed of ITO/NiOx/MXene/SAM/Cs0.05MA0.15FA0.8PbI3/C60/BCP/Ag achieves power conversion efficiency 26.2% (certified) showing high operational stability at 85℃ and under 1 SUN light exposure (unencapsulated, >2000 h)[1]. As an extension of this study, boron-intercalated MXene was prepared as a standalone hole-selective layer, free from combination with NiOx. This MXene-based PSCs also shows durable stability under exposure to high humidity (60% RH) showing 90% retention for 2100 h [2]. Moisture-resistant PSCs can also be designed by using dopant-free hydrophobic organic HTL. Our n-i-p type device with a unique doner-accepter triazine derivative as dopant-free HTL shows operational stability over 2500 h in ambient air [3]. SAMs acting as interfacial modifiers form charge-selective junction interfaces without the use of electron transport layer (ETL) and HTL. A device in which interfaces of perovskite absorber are fully functionalized with SAMs [4] exhibited high durability, free from degradation caused by transport materials. Research progresses on improving device durability through interfacial molecular engineering will be introduced.

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.
