  • Thermal management of non–concentrating photovoltaic panels under extreme ambient conditions

    Solar photovoltaic modules have reduced efficiency levels when the ambient temperature is very high. In this paper, the temperature and the efficiency of a non–concentrating flat plate collector is determined by a one dimensional steady state analysis at different solar radiation levels for the city of Riyadh, Saudi Arabia where the radiation intensity and ambient temperatures are very high. The ...

  • Study of photoluminescence quenching and DC conductivity measurements in polymer-SWNT composite films for various SWNT concentrations

    Conducting polymer-SWNT composite films have a high potential in the area of photovoltaic devices and light emitting diodes (LEDs). SWNTs have high electron affinity and high mobility for electrons. As a result of this, the separation of photoinduced charges in the solar cell is very fast and efficient. For LEDs, the polymer-SWNT composite films act as efficient electron transporting layer (ETL). ...

  • Effect of seed particle size and ammonia concentration on the growth of ZnO nanowire arrays and their photoconversion efficiency

    ZnO nanowire arrays were synthesised for dye-sensitised solar cell applications using the chemical bath deposition technique. To study the effect of the particle size in the seed layer on the growth and resultant photoconversion efficiency, we prepared various seeded FTO substrates by repeating the seed layer sol-gel coating process. It was found that changing the number of coating process ...

  • AUS$2.4bn investment for ultra high efficiency solar power station

    Breakthrough photovoltaic concentrators producing ultra high efficiencies have been developed by Solar Systems (an Australian company) and deployed in a number of projects, on a relatively small scale in collaboration with the Australian Government. Beginning with an AUD$0.424 Billion, 154MW phase in Australia, this project aim to deploy at least 1GW of power stations technology across Australia, ...

  • How Does Solar Energy Transformed into Electricity?

    Many years ago, solar energy was never been the subject of all talks. Basically because the solar energy was never given that importance in people’s day to day life before. They just ignore and did not give attention on its importance. They fail to realize the importance of it. Now, as the period of modernized society where new technologies and innovations occurred came, the demand for ...

  • Alternative scenarios of the utilisation of renewable energy sources in small prefectures: a case study in Lasithi Prefecture, Greece

    The sector of Renewable Energy Sources (RESs) is growing very fast, with many innovations and applications becoming a reality. The continuous reduction of natural resources has forced all policymakers to turn to alternative energy sources. The total energy (oil and electricity consumption) consumed in the prefecture of Lasithi during the years 1997?2002 in correlation with the RES exploitation ...

  • Clarification of algae-laden water using electrochemical processes

    Algae contamination of surface water and drinking water supplies is a significant problem particularly in rural areas. A decentralized inexpensive technology that would effectively remove algae from water would be beneficial. Electrocoagulation (EC) combined with electroflotation (EF) as a single process (ECF) is a promising algae harvesting technique with no moving parts that may be powered ...

  • Plan B 4.0 by the numbers - data highlights on solar energy

    Concerns about global warming, rising fossil fuel prices, and oil insecurity have prompted calls for a new energy economy, one that replaces fossil fuels with renewables. The sun is an enormous reservoir of energy; in fact, the sunlight reaching Earth in just one hour is enough to power the global economy for a whole year. Harnessing some of this energy is an essential component of Earth Policy ...
