The identification of recombination centers in organic solar cells
To achieve high efficiency bulk heterojunction organic solar cells, it is necessary to identify and minimize the recombination centers that limit the performance. There is growing evidence that the dominant recombination is through trap states [...]
Characterization of Solar Grade Silicon Contaminants
The term ‘Solar Grade Silicon (SoG)’ has been used for many years but until recently, there were no specifications as to what this actually meant. Without specifications, suppliers of silicon have been using ‘number of [...]
Improvement of Silicon Solar Cell Metallization with Printed Metal Nanoparticle Inks
The process and quality of metallization greatly affects the performance and cost of solar cells. Screen printing of silver paste and fire-through of the silicon nitride antireflection layer is the most widely used method for [...]
Direct Pulsed Laser Crystallization of Photoactive thin films at Room Temperature
Photoactive semiconductor materials used for thin film solar cells have been considered one of the most promising technologies with demonstrated high efficiency in both lab scale cells. World-wide research and development (R&D) have been carried [...]
New Technology: DG Controller for Intelligent Hybrid-Renewable Generation Dispatch to Smart-Grid
XTRLs International has developed a new control technology for intelligent load-following and demand-response dispatch of customer-owned integrated Distributed Generation in smart-grid applications by Utility Distribution Companies (UDC), demand response aggregators or end-user customers. The DG [...]
Bioenergy production from wastes and wastewaters in China
China is investing billions of US dollars annually on renewable energy production. China is leading the world not only in wind and solar energy production, but also in harnessing bioenergy from wastes and wastewater. The [...]
Mobile Hybrid Structures: Feasibility and Advantages
Several novel configurations of mobile oceanic renewable energy systems are presented with emphasis on advantages over existing planned offshore development. Consideration of certain historic weather and levelized cost of energy data indicates profitable operation for [...]
Competitive Advantageous Green Energy Technologies – Photovoltaic, Geothermal & Wind
The objective of the study is to identify the changes in trends of non-fossil fuel energy industry demand, growth and opportunities. The study uses the databases such as patents, news events, income/financial statements to assess [...]
Interactions of Rocks with Supercritical CO2 and Water in Enhanced Geothermal Systems and Beyond
There is an abundance of heat but lack of fluids underground. Current drilling and fracturing technologies can provide necessary access to the hot rocks, creating so-called Enhanced Geothermal Systems (EGS). Despite the 100-fold increase in [...]
