    In this work, lithium fluoride nanostructures were synthesized by utilizing a wet chemical solution approach. LiFx is a viable option for replacing the n-doped amorphous silicon (a-Si: H(n)) layer in silicon heterojunction (SHJ) solar cells due to its low work function and wide-bandgap. A scanning electron microscope (SEM) was used to measure the surface morphology, while atomic force microscopy (AFM) was used to measure the 3D profile and roughness of LiFx nano-structures. The optical transmittance spectra of LiFx nano-structures were measured using a UV-Vis spectrometer. In addition, using various film thicknesses and LiFx work functions, simulated research for a complete photovoltaic device (electron carrier selective contact solar cell) was carried out.
