Some Physical Properties of CdO Thin Films Used as Window Material in Photovoltaic Solar Cells

Abstract

CdO thin films which can be used in photovoltaic solar cells as window material were obtained on glass substrates at 250°C and 300°C substrate temperatures using Ultrasonic Spray Pyrolysis (USP) technique. The electrical, optical, structural, and surface properties of the films were investigated for two different substrate temperatures. After all investigations, it is concluded that, the CdO thin films can be used in photovoltaic solar cells as window materials and cell efficiencies can be increased using different growth parameters.     

Design concept for an ecological relaxing textile product using solar energy

We can enhance our quality of life and reduce environmental impacts by making improvements in textile product design. By thinking about the environment when we design, choose and use technology, we can play an important part in building a better world for the future. If we are going to live in a sustainable way, the technology that we use has to be sustainable.

This paper provides an insight into how the design of textile products could provide for a more sustainable future. It describes a design concept for an ecological relaxing textile that uses photovoltaic cells to collect and store solar energy and to power an electronic relaxing system. This design may help improve our quality of life now and in the future.

The raw materials and processes, the electronic devices and the dimensions of solar energy for this application are analysed from an environmental perspective. The solar relaxing textile can facilitate our daily life by providing increased comfort and well being, and also acts as an indirect message to use renewable energy within textile support, in order to preserve our ecology.     

Thermal performance of a central annular cavity vessel with fins of a box-type solar cooker

Solar cooker is an alternate device used for reducing the problems of energy supply for cooking needs, especially in rural households. Though solar cookers have been commercialised in rural and other domestic areas, further research is still required to enhance the efficiency of the solar cooker. Previous studies have helped to ascertain that the central annular cylindrical hole in the cooking vessel reduces the length of the heat-transfer path and provides higher heat-transfer rate to the water kept in the vessel. Convective heat transfer can be further increased by providing additional surface area in the cylindrical hole. This study proposes a new cooking vessel with central annular cavity and fins attachment that will help in increasing the heat-transfer rate to the cooking vessel. Experiments are conducted with three types of vessels, i.e. conventional cooking vessel, cooking vessel with central annular cavity and cooking vessel with rectangular fins in the central annular cavity. For the annular cavity with fins vessel, a peak temperature of 98°C is observed. The maximum temperature difference of 30°C has been observed between annular cavity vessel with fins and conventional vessel. As the height of the lug is also expected to play an important role, experiments are conducted to determine the effect of lug height on the heat transfer to the cooking vessel. This study indicates that a lug height of 9 mm is optimum for maximum heat transfer to the cooking vessel.

原子氧对不锈钢的作用

目的研究空间原子氧辐照对不锈钢性能的影响。方法将不锈钢试样置于束流密度为2.5×10~(16)atoms/(cm~2·s)的原子氧束中进行辐照试验,最长辐照时间为300 min。研究随辐照时间增加,试样质量、光学性能、接触角、耐磨性能、耐腐蚀性能的变化。结果原子氧辐照后,不锈钢表面生成氧化物质量增加;随辐照时间增加,试样光谱反射系数呈下降趋势,太阳吸收比增加;原子氧作用导致不锈钢接触角增大,耐磨性能提高,耐腐蚀性能下降。结论得到的不锈钢原子氧环境效应数据,可为其在低轨航天器上的应用提供理论基础。     

Looking beyond incentives: the role of champions in the social acceptance of residential solar energy in regional Australian communities

Research into renewable energy adoption is increasingly identifying that the successful implementation of renewable energy projects is influenced by a combination of market, community and socio-political acceptance of renewable energy technology. This research uses case studies in two regional Australian communities to examine the social acceptance of residential solar energy, in particular under the influence of financial incentives and social interactions. Fifty-five semi-structured interviews with members of the local community, industry and government were undertaken between May and October 2015. Respondents were asked about their perceptions and knowledge of solar energy and incentives to support its adoption, and their interactions with actors important in the diffusion process. Responses indicated that financial incentives motivated solar adoption; however, social interactions in the communities also contributed to decision-making. In one case study, a local “solar champion” built a private solar farm to demonstrate the technical feasibility of solar, assisted community members with physically installing their own systems and helped community members to maximise the financial benefits of their solar installations. This solar champion contributed to this community having an earlier and more rapid rate of small-scale solar adoption compared with the second case study community. The second case study community included two individuals interested in promoting solar energy; however, they were less integrated with the community’s process of adopting solar, resulting in community members experiencing substandard installations and consequent distrust of the solar industry. This research concludes that local context influences solar adoption through complex interactions among market, community and socio-political acceptance.
