FeCl₃-functionalized graphene oxide/single-wall carbon nanotube/silicon heterojunction solar cells with an efficiency of 17.5%

Abstract

Single-wall carbon nanotube/silicon (SWCNT/Si) heterojunction solar cells are no longer a laboratory curiosity, but the commercial manufacture of devices with a high and stable conversion efficiency remains a big challenge....

Interfacial Chemical Bridging Constructed by Multifunctional Lewis Acid for Carbon Nanotube/Silicon Heterojunction Solar Cells with an Efficiency Approaching 17.7%

“…The SWCNT films employed in this study were synthesized by the FCCVD method, and the as-prepared films were directly transferred onto a target substrate using a simple method. [9,[36][37] Figure S1a (Supporting Information) indicates the procedure of preparing Si substrate with 3×3 mm 2 active area surrounded with ≈300 nm thick SiO x , and the SEM image of the obtained substrate is shown in Figure S1b (Supporting Information). Asprepared SWCNT film was transferred onto the Si substrate to form SWCNT/Si heterojunction (Figure S1c, Supporting Information).…”

Recent advances of carbon nanotubes in perovskite solar cells

“…The CNT films not only have excellent optical and conductive properties but also show high mechanical stability, abundant raw materials, and easy preparation, and are considered to be alternative materials for TEs. Cheng's group fabricated high‐crystallinity and small‐bundle SWCNT films using a floating catalyst chemical vapor deposition (FCCVD) and gas phase filtration techniques, exhibiting outstanding transparent conductive properties 40–44 . Furthermore, they synthesized a carbon‐welded isolated SWCNT network, composed of ∼85% isolated tubes 45 .…”

Rational and key strategies toward enhancing the performance of graphene/silicon solar cells

“…13 Graphene is another carbon nanomaterial, which has superior electrical, optical, and mechanical properties, high carrier mobility, as well as low absorbance, [14][15][16] and can be manufactured and handled into ultrathin films, 17,18 sheets, [19][20][21] ribbons, 22,23 fibers, 24,25 and large-surface papers. 26 Hence, the applications of this graphene have been widely investigated in different fields, from spectroscopy to nanoelectronic devices, photonics, 27 solar cells, [28][29][30] transistors, 31 fuel cells, 32,33 supercapacitors, 34,35 photocatalysts, 36 sensors, 37 mass spectrometry, 38 and drug delivery. 39 In addition, with the introduction of graphene in 2004, many 2D materials were successfully manufactured using different methods, such as chemical and physical vapor deposition methods.…”
