The phrase "absorber layer can be" is correct and usable in written English.
It can be used in contexts discussing materials, physics, or engineering, particularly when describing the properties or functions of an absorber layer.
Example: "The absorber layer can be optimized to enhance the efficiency of solar panels."
Alternatives: "the absorber layer may be" or "the absorber layer is capable of".
In this case, the optical losses in the absorber layer can be significant.
Using the same device structure, the CIGS absorber layer can be replaced by indium-free absorbers, such as Cu2ZnSn(S,Se)4 (CZTSSe) with kesterite structure.
For example, Si nanostructures, such as Si nanowires (SiNWs) have been incorporated into solar cells for light trapping, so that thinner Si absorber layer can be used to lower the material cost [1 3].
Besides, large carrier diffusion lengths of up to 1 μm have been observed in mixed-halide perovskites which also lends support to the claim that thicker absorber layers can be used [60].
The approaches followed to electrodeposit CIGSe absorber layers can be classified into two routes: (1) by one-step deposition, where co-deposition of all the elements takes place at a single potential followed by post-treatments or (2) by two steps to multi-step depositions to deposit either via binary phase deposition or element by element.
In terms of nanoparticle shape, besides spherical nanocrystals, elongated Bi2S3 nanorods have also already been obtained in a polymer matrix using metal xanthate precursors.[ 20] Currently, no systematic studies on how the nanomorphologies of in situ prepared absorber layers can be tailored in order to optimize the device performance exist.
One or several layers can be used.
The simulation results obtained in this study show an enhancement in FF and Jsc which are consistent with the energy band alignment of HTM and ETM with the absorber layer which can be seen in Figs. 1c and 2a, respectively [26].
Therefore, for this study, we have chosen the material combination P3HT/CdS as a model system to investigate if the absorber layer nanomorphology can be tuned by the molecular design of the precursors.
By optimizing the absorber structure and the associated thickness, the absorbing bandwidth of the multi-layer absorber can be largely broadened.
After combining those compartments, the resultant acoustic impedance and acoustic absorption coefficient of the multi-layer acoustic absorber can be obtained.
