Carbon nanomaterials for photovoltaic process

Recent Trends on Electrochemical Sensors Based on Ordered Mesoporous Carbon

“…More recently, the emergence of nanoscale and multi-dimensional forms of carbon such as 0D fullerenes, 1D carbon nanotubes, 2D graphene and related materials, or 3D nanostructured porous carbon materials, has contributed to expand considerably the development of carbon electrodes. Thanks to their additional properties originating from their nanostructures, i.e., ultra-high conducting surface area, ordered structure at the nanoscale, nanoelectrocatalysis promoting electron-transfer reactions (most likely due to the presence of edge-plane-like sites [ 6 ]), these advanced materials have been the subject of numerous investigations in the past few decades [ 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 ]. They are especially promising in the field of energy conversion and storage [ 7 , 8 , 9 ], photovoltaics [ 10 , 11 ] or electrochemical sensors [ 12 , 13 , 14 ] and biosensors [ 15 ].…”

Understanding Wear Interface Evolution to Overcome Friction and Restrain Wear of TiAl–10 wt%Ag Composite

“…Because of having the combinations of low density, excellent mechanical property, and outstanding thermal behavior, TiAl alloys are widely applied in the manufacturing of aerospace components like turbine blades and automobile components like exhaust valves . In recent years, the necessity of minimizing friction and decreasing wear in moving mechanical assemblies drives the further optimization of friction and wear behaviors of TiAl alloys . Additionally, the excellent tribology behaviors of TiAl alloys are also advantageous to further increasing the useful life of TiAl alloy‐based machinery components …”

Dry‐Deposited Transparent Carbon Nanotube Film as Front Electrode in Colloidal Quantum Dot Solar Cells

“…Although promising results have been obtained in photovoltaic devices with transparent SWCNT films as front electrode using either solution‐processed or dry‐transferred SWCNT film, the device efficiency is still inferior to that of the ITO‐based devices. The reasons for the inferior performance are generally identified as either higher electrical resistance, lower light transmission, or a combination of both compared to ITO electrodes . In previous work, we found that the transparent electrode and device configuration of the solar cell significantly affected the optoelectronic properties within CQD solar cells, such as the intensity and distribution of the optical electric field, which determines the exciton generation and thereby the overall device performance .…”

“…The reasons for the inferior performance are generally identified as either highere lectrical resistance, lower light transmission, or ac ombination of both compared to ITOe lectrodes. [6,19,[27][28][29] In previousw ork, we found that the transparent electrode and device configuration of the solar cell significantly affected the optoelectronic properties within CQD solarc ells, such as the intensity and distribution of the optical electric field, which determines the exciton generation and thereby Single-walled carbon nanotubes (SWCNTs) show great potential as an alternative material for front electrodes in photovoltaic applications, especially for flexible devices. In this work, ap ress-transferred transparent SWCNT film was utilized as front electrode for colloidal quantum dot solarc ells (CQDSCs).…”
