Figure 4From: Characterization of photovoltaics with In2S3 nanoflakes/p-Si heterojunctionAbsorption and transmission spectra. (a) Absorption spectra of the various thicknesses of the In2S3 film measured at room temperature. The inset shows a function of photon energy. (b) The transmission spectra of 400-nm-thick AZO deposited on the In2S3 film with various thicknesses.Back to article page
