Benzosiloles and their π-extended derivatives are present in many important advanced materials due to their excellent physical properties. Especially, they have found many potential applications in the development of novel electronic materials such as OLEDs, semiconductors and solar cells. In this review, we have summarized several main approaches to construct (di)benzosilole derivatives and (benzo)siloles fused to aromatic five- and six-membered heterocycles.

Abstract CdS thin film solar cells with a p-Cu2S - n-CdS-heterojunction were made by vacuum evaporation of CdS films on Mo substrates and dipping of these films into Cu+-ion solution. The influence of various annealing times and repeated dipping into Cu+-ion solution were investigated and discussed. Etching the CdS films with various etchants gave different results. In this way the solar cells yielded efficiencies up to 5.2%. The influence of interfaces of Ag and Zn between the Mo-substrat and the CdS film was studied.

Need To Evaluate

Considering optimization of the technology and production of Solar Cells an overall goal is to lower the production costs per Watt through optimization of the parameters of Solar Cell. The dominant material up to now for the majority of commercially produced solar cells is crystalline silicon (c-Si). A lot of efforts has been undertaken to increase the electrical efficiency of Si based solar cells above 20% [3-5]. Unfortunately, efficiency improvements are often reached only with the help of costly process steps and as result without possibility to use such improvements in industrial products. One of the trends in achieving higher efficiency in monocristalline Si based Solar Cells is introduction of complicated spatial structure on absorbing surface of SC. Reports indicates expectations of efficiencies as high as 24% in laboratory samples but with significant raise in costs for Spatial SC production (Fig. 1). It is clear that optimization of technological steps and parameters must be considered thinking about introduction of Spatial SC. Optimization in the case of Spatial SC must be provided by two steps: first of all we need to evaluate impact of spatial structure to physical properties of the SSC and in the next step evaluate technological possibilities for production of the SSC with optimized physical characteristics.

AbstractWe have been studying new approaches to conventional Chemical Bath Deposition (CBD) of chalcogenide containing materials, using continuous circulation and replenishment of CBD solution over a heated substrate. Crystalline thin films produced by this method offer potential for use in solar cell devices or other optoelectronic applications. Films of CdS, ZnS and the ternary material CdxZn1−xS have been deposited on TO-glass substrates. In this paper we demonstrate our approach for the deposition of CdS films. These have been characterized by XPS, SEM, XRD and UV/vis spectroscopy and shown to be good quality. The films have been used to fabricate Au/CdTe/CdS/TO-glass solar cells of efficiency 10.1% under AMl.5 illumination.
