Optimization of Zn Concentration in Chemically Deposited (Cdx-Zn1-x)S Nanocrystalline Films for Solar Cell Applications
摘要： Optimization of Zn Concentration in Chemically Deposited (Cdx-Zn1-x)S Nanocrystalline Films for Solar Cell Applications. An attempt has been made to optimize the Zn concentration in chemically deposited (Cdx-Zn1-x)S (x = 0.2, 0.4, 0.6, 0.8) films on ITO substrate by varying the Cd/Zn composition ratio to enable them to absorb a sizable fraction of solar photons. The phase purity and nano-crystalline character of as-deposited films are established by XRD. Lattice parameters and band-gap values are found to change almost linearly with Cd/Zn composition ratio. The surface morphology supports the nano-crystalline nature of deposited films. The Eg values for (Cdx-Zn1-x)S nanocrystalline films estimated from absorption spectra and corresponding Tauc’s plots range from 2.63 eV to 2.81 eV. The optical behavior in terms of absorption and PL spectra suggests that these films are suitable for application in photovoltaic devices. The electrical resistivity of different (Cdx-Zn1-x)S films has been measured as a function of Zn concentration. The efficiency of resultant CdTe/(Cdx-Zn1-x)S cell is calculated to be approximately 11%.

Incorporation of an efficient <i>β</i> -In <sub/>2</sub> S <sub/>3</sub> thin film as window material into CdTe photovoltaic devices
摘要： ABSTRACT. – Polycrystalline thin film CdS has been used as window material in photovoltaic solar cells. Its ideal band gap (2.45 eV), low resistivity and electron affinity made this material the most used in photovoltaic engineering; However, nowadays a cadmium free material with similar properties is necessary. β-In2S3 has shown adequate physical properties to be applied on CdTe, CIGS, CIS and CZTS solar cells. β-In2S3 thin films were grown by chemical bath deposition technique and thermally treated under different conditions. Their structural, optical, morphological and electrical properties were studied, and efficient cadmium free window layer was obtained and implemented on CdTe solar cells. The presented results are discussed.
