Photovoltaic performance improvement of organic solar cell with ZnO nanorod arrays as electron transport layer using carbon quantum dots-incorporated photoactive layer

A self-powered photodetector through facile processing using polyethyleneimine/carbon quantum dots for highly sensitive UVC detection

“…FTO and Au were used as the bottom and top electrodes for the collection of electrons and holes, respectively. [82][83][84][85] Here, a thin lm of PEI is sandwiched between the CQD and FTO/glass substrate. The PEI interfacial layer supports close lm formation and separates the top and bottom electrodes.…”

“…[102] Figure 8(b) depicts the improved photovoltaic performance of organic solar cells (OSCs) incorporating CQDs with ZnO nanorod arrays. [103] While not directly related to photocatalysis, Figure 8(c) highlights the versatility of these materials by depicting a highly sensitive fluorescent probe for sparfloxacin determination. This probe integrates various components, including nitrogen-doped graphene quantum dots, zinc oxide-decorated carbon foam, and magnetite within a molecularly imprinted polymer matrix.…”
