In this study, device modeling and simulation are conducted to explain the effects of each layer thickness and temperature on the performance of ZnO/CdS/CIS thin film solar cells. Also, the thicknesses of the CIS and CdS absorber layers are considered in this work theoretically and experimentally. The calculations of solar cell performances are based on the solutions of the well-known three coupling equations： the continuity equation for holes and electrons and the Poisson equation. Our simulated results show that the efficiency increases by reducing the CdS thickness. Increasing the CIS thickness can increase the efficiency but it needs more materials. The efficiency is more than 19% for a CIS layer with a thickness of 2 μm. CIS nanoparticles are prepared via the polyol route and purified through centrifugation and precipitation *** nanoparticles are dispersed to obtain stable inks that could be directly used for thin-film deposition via spin *** also obtain x-ray diffraction（XRD） peak intensities and absorption spectra for CIS experimentally. Finally, absorption spectra for the CdS window layer in several deposition times are investigated experimentally.

We have found an incorrect formula to estimate the root mean square(rms)amplitude of the molecular vibration in the molecular optomechanics systems reported by *** et al.[***.5,450–456(2017)[CrossRef]].In contrast with common optomechanical systems,the equilibrium position for molecular optomechanics systems used in the letter cannot be achieved by the equipartition ***,we achieve the effective temperature of molecules and then provide a corrected formula for the estimation of the rms amplitude of molecular *** defined effective temperature into our new formula,we show that the minimal measurable force is(𝐹≈1.7×10^(−14) N),which it is 1 order bigger than the result of the main paper,and it is also in accordance with numerical calculation through the Lindblad master equation.
