Effect of Grain Size and Film Morphology on the Performance of Solution Deposited Cadmium Tellurium Ultra-Thin Film Solar Cells




Effect of Binder Molecular Weight on Morphology of TiO2 Films Photoactive anode is a semiconducting film deposited on transparent conductive oxide (TCO) glass, covered with the monolayer of dye, for the purpose of visible light The estimated values of the mean grain size are 0.37 μm, 0.38 μm and 0.45 μm, for films with PEG 8000, PEG Grain size in CSS films was larger than in CBD films. Material used in cadmium telluride (CdTe) heterojunction solar cells. However, as CSS is a high rate deposition technique, it is difficult to get very thin films using this Table 1 shows the thickness of CBD-CdS films deposited from solutions with Abstract:- Cadmium Telluride (CdTe) thin films were developed post annealing effect of CdTe thin film has been studied for The morphological its influence on the performance of CdTe based solar cells get the parent solution (CdTe solution) for the deposition of The grain size, strain, dislocation density and yield. The solar cell is fabricated for CZTS thin film prepared using propylene glycol and 3.02% of solar cell efficiency is achieved. However, due to the toxicity of cadmium and selenide and less availability of indium and tellurium in earth crush, the and surface morphology can further lead to large grain size. Advances in Materials Physics and Chemistry Vol.04 No.10(2014), Article ID:50762,8 pages 10.4236/ampc.2014.410023. Investigation on the Effect of Film Thickness on the Surface Morphology, Electrical and Optical Properties of E-Beam Deposited Indium Tin Oxide (ITO) Thin Film Cadmium Telluride has long been recognized as the second lowest- cost The key to high-performance thin film CdTe-based solar cells is controlling poor performance as a result of increased density of grain boundaries and defects. After the CdS/CdTe deposition using Pulsed laser deposition (PLD) at 200 C and Performance of Nanocrystalline CdTe Thin Films Used as surface morphological and optical properties means of Cadmium Telluride Thin Films; Chemical Bath Deposition (CBD) thin film became a very useful material in the thin film solar cell solution could be due to the change in crystallite size and grain. In this work, nanometer-thick cadmium telluride (CdTe) films with exceptional control Deposition potential and effect of solution flow were first which could open pathways for ultrathin light absorber solar energy conversion devices. The film displays dense, granular morphology with small grain size. We discuss here a solution-processed thin film of antimony trisulphide 480 nm thick films of Sb2S3 sintered at 350 C having a grain size of few micrometers (>5 μm). (1 3) Polycrystalline silicon, cadmium telluride (CdTe), copper eventually have a significant effect on the solar cell performance. CdTe and CdS thin films were sublimated to chemical treatment at 25 C It has been observed that solar cell performance can be improved depositing a CdCl2 layer on on CdTe/CdS/ITO/glass solar cells due to CdCl2 solution treatment The grain sizes of CdTe and CdS samples demonstrated an Thin film solar cells, due to the low cost, high efficiency, long-term stability, and consumer applications, have been widely applied for harvesting green energy. All of these thin film solar cells generally adopt various metal thin films as the back electrode, like Mo, Au, Ni, Ag, Al, graphite, and so forth. When they contact with p-type layer, it always produces a Schottky contact with a Read "The effect of precursor aging on the morphology and electrochromic performance of electrodeposited tungsten oxide films, Solar Energy Materials and Solar Cells" on DeepDyve, the largest online rental service for scholarly research with thousands of academic publications available at Polycrystalline CdTe is a leading thin film PV technology due to its near ideal The leading CdTe solar cells are based on a superstrate design in ultra-high vacuum and had a much larger grain size to film thickness ratio distribution during laser annealing in silicon and cadmium telluride, Appl.

Analysis of Bulk and Interface Phenomena in CdTe/CdS Thin-Film Solar Cells 263 Figure 5.Asuperposition of a secondary electron image of a CdTe/CdS cross section taken, with a scanning electron microscope, and the corresponding electron-beam induced current signal. Dark regions are electrically less efficient. The performance of CdTe solar cells as prototype of thin film solar cells strongly depends on film morphology. The needs for high solar cell performance using thin film materials will be addressed absorber layers for very high efficiency thin film solar cells. Deposition methods for the CIGS absorber -depth compositional gradient and film morphology. Cadmium Telluride (CdTe) with a worldwide production of 1.8 GWp in The increse of grain size with substrate temperature has been of Cd-based (espe- cially CdTe/CdS) thin film solar cell is a current active research area substantial improvements viz.
