The paper focuses on the use of biomass in the conditions of the Slovak Republic. The importance and position of biomass within renewable energy sources is highlighted in the introduction. Documents such as laws, studies, and strategies which have been developed with the aim to increase the share of renewable energy sources within the energy mix are listed here. The issue of biogas and its possible sources in the Slovak Republic was also solved. An important part of the paper is the presentation of the current statistical data concerning to the number of biogas stations and also information about the material used for gasification purposes in SR. A separate part of the contribution consists of the field research results focused on selected biogas stations in western Slovakia. We provide basic technical specifications, biomass suppliers and statistical data about heat and electricity production for each station. Selected stations were located in villages: Smolinské, Malý Cetín, Ružindol, Chynorany and Kolíňany.
Due to the particular advantages of amorphous silicon or its alloys with carbon in comparison to conventional crystalline materials makes such a material still interesting for study. The amorphous silicon carbide may be used in a number of micro-mechanical and micro-electronics applications and also for photovoltaic energy conversion devices. Boron doped thin layers of amorphous silicon carbide, presented in this paper, were prepared due to the optimization process for preparation of heterojunction solar cell structure. DC and AC measurement and subsequent evaluation were carried out in order to comprehensively assess the electrical transport processes in the prepared a-SiC/c-Si structures. We have investigated the influence of methane content in deposition gas mixture and different electrode configuration.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
