The commercialisation of perovskite photovoltaic (PV) technologies requires advancements in large-area module efficiency, scalable and cost-effective manufacturing, and long-term operational stability. Stability issues in perovskite solar cells (PSCs) often stem from the materials used in the hole-transporting layer (HTL). Innovative, sustainable, and affordable hole-transport materials (HTMs) are crucial to address these challenges. Cu₂ZnSnS₄ (CZTS), an earth-abundant p-type semiconductor traditionally used as a light-absorbing material in heterojunction solar cells, has recently gained attention as an HTL for PSCs due to its desirable electronic properties.
This study explores the synthesis and application of CZTS nanoparticles (NPs) as an HTM in PSCs. The nanoparticles were produced using a hot-injection method under an oxygen-free environment and subsequently processed into an ink formulation for spin-coating. The resulting CZTS thin films, approximately 50 nm thick, were annealed to ensure structural and optical transparency in the visible solar spectrum. Comprehensive material characterisation—including transmittance, Raman spectroscopy, UV-Vis spectroscopy, scanning electron microscopy, and X-ray diffraction—confirmed the quality and stability of the CZTS layers.
Preliminary findings indicate that PSCs employing CZTS as an HTL demonstrate superior stability compared to conventional organic HTM devices. Over one month, the CZTS-based devices retained or even improved their photovoltaic efficiency, unlike organic HTL-based devices, which experienced significant degradation. Current-voltage measurements, external quantum efficiency and photoluminescence spectroscopy analyses revealed enhanced charge injection in the CZTS HTL. These results suggest that CZTS is a robust and sustainable alternative to traditional HTMs, paving the way for more durable perovskite PV technologies.
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.
