Effect of annealing on the loss kinetics of charge carriers in CdS films

The properties of solar cells are dependent on more than the choice of materials for the photoconducting film. In one paper from the Special Topic: CIGS, CdTe, and other thin film solar cells, the role of the annealing process on the kinetics of electron trapping processes is investigated through the time resolved microwave photoconductivity technique.

Optimization of power generation from a set of low-temperature abandoned gas wells

Geothermal energy provides a potentially vast reservoir of clean energy. However, most of the known high-temperature aqueous sources are already in use. This paper focuses on the potential for low-temperature sources, specifically abandoned hydrocarbon wells in Iran, as alternative geothermal energy resources. The authors present a simple model for extracting energy and analyze the power output for specific cases.

Assessing justice for renewable energy technologies

An important part of the development of renewable energy systems is the impact of new technology on the lives of individual people. In their recently published paper, “Equity dimensions of micro-generation: A whole systems approach”, authors C. Adams, P. Taylor, and S. Bell present a whole-systems methodology developed as part of the work of the Interdisciplinary Cluster on Energy Systems Equity and Vulnerability (InCluESEV).

Investigating ships fueled by seawater

With a volatile market for the environmentally unfriendly fossil fuels, what could be better than naval ships being able to produce jet fuel from seawater? In a recent article from Journal of Renewable Energy that was featured by NBC News, the feasibility of ships fueled by the sea is discussed, and the outlook is promising.

Design, construction, and testing of a parabolic trough solar concentrator for hot water and low ...

The authors present a parabolic trough solar concentrator that does not require complicated technology or skilled labor to assemble. The thermal performance of the unshielded receiver (according to the Standard ASHRAE 93-1986 (RA 91) protocol) reaches peak efficiencies close to 60%.
