Low temperature processed Hole transport materials(HTMs) are beneficial for scalable production of inverted planar perovskite solar cells (PSCs) for wider choice of substrates. In this concern, Carbon derivative such as reduced grapheme oxide (r-GO) is a popular choice of HTM due to low toxicity, abundance in nature and low temperature one step spin-coating process. However, deposition of r-GO may result in poor overall device performance due to the low coverage on the corresponding substrates. Hence introducing an interfacial material with matched energy level between the r-GO HTM and the corresponding perovskite absorber resulting in bilayer HTM configuration may increase the overall performance of an inverted planar PSC. Here, in this work, we report copper (I) thiocyanate (CuSCN) as an efficient interlayer in low temperature processed inverted planar PSC. We have systematically optimized the thickness of CuSCN interlayer at the r-GO/Perovskite interface to enhance the stability and photovoltaic performance of low temperature processed inverted planar PSCs over a surface area of 1.02 cm2. The successful coverage of CuSCN over the uncovered areas of r-GO increases the photovoltaic performance of the PSC. Simultaneously, the r-GO/CuSCN bilayer HTM leads to better hole transportation and enhanced carrier mobility to the perovskite interface. With matched energy level, the r-GO/CuSCN bilayer completely covered the surface of ITO and successfully prevented the recombination at the interface with the perovskite absorber. The r-GO/CuSCN bilayer HTM based PSCs showed a high efficiency of 14.28%. Additionally, enhanced stability has been observed for the r-GO/CuSCN based PSCs retaining its initial efficiency after 500h light soaking.
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.
