Furthermore, small bandgaps would enable UV-Vis radiation absorption by Phos-Fullerene nanostructures as required for optoelectronic applications. In fullerene-based polymer solar cells, phosphorene has enabled a strong absorption between 300-800 nm and better energy alignment in the device layers, which is significantly beneficial to the charge transfer, exciton dissociation, and reduce charge recombination, consequently enhancing the power conversion efficiency . In addition, C60 allowed absorption in the visible range for mm-scale heterojunction phosphorene-based photodetectors, where synergistic effects enable high photoresponse from the visible to near-infrared spectrum . Accordingly, synergistic properties of Phos-Fullerene complexes could inspire experimental/theoretical studies on its uses for future generation solar energy harvesters or as active layers within photodetector devices. To support these points, we verified the UV-Vis spectrum of the proposed nanostructures in n-hexane as a solvent commonly implemented to study the fullerene absorbance (Fig. ). Intrinsic phosphorene shows a wide absorbance from the infrared, which increases in intensity below 500 nm as recorded from UV-vis spectrophotometry . In comparison, most free fullerenes absorb high molar absorption coefficients at the UV region below abs<400 nm (Fig. ). Phos-Fullerene nanostructures almost resemble the absorption spectra of free phosphorene (Fig. ), but a remarkably improved absorption at higher frequencies is reached (abs400-500 nm). Then, fullerenes maximize the phosphorene absorbance at the UV-Vis region, denoting the emerging synergistic effects for optoelectronics and photodetectors.
