The effect of boron doping on the optical, morphological and structural properties of Cu₃SbS₃thin films preparedviaspin coating

Abstract

For the first time, boron doped Cu3SbS3 thin films were produced via spin coating method. Boron doped Cu3SbS3 thin films will provide new dimensions for the design of environmentally friendly, low cost and highly efficient solar cell absorber layer.

The effect of zinc and sodium borate doping on the structural, morphological, optical, electrical and electrochemical properties of PEDOT:PSS thin film electrodes for flexible and transparent supercapacitor applications

“…In this graph, the intersection of the linear part of the curve with the abscissa was used to define the forbidden bandwidth and plotted to determine the effect of doping on the energy gaps of the PEDOT:PSS film. The Tauc equation used to calculate the optical band gaps of the prepared thin films is as follows: 49 αhν = B ( hν − E g ) n where ν , α , h , and E g represent the photon's frequency, absorption coefficient, Planck constant, and bandgap energy, respectively and B is a constant. The exponent n , whose value depends on the kind of electronic transition, has a value of 2 for direct transition band gaps.…”
