Conducting a study and field experiments, a doctoral student in the School of Architecture and Design at the University of Kansas (KU) shows that PV panels installed over a green roof perform an average of 1.5% better, compared with panels over highly reflective or black surfaces. Typically, the efficiency of a photovoltaic panel is measured under standard testing conditions, in a temperature of 77° Fahrenheit (25° C). With every degree the temperature increases, performance...

Researchers at Duke University in North Carolina (US) have created a new technique to make hybrid thin-film materials. The study could provide an avenue to scale-up hybrid perovskite thin-film deposition for solar cells and also pave the way to new light-emitting diodes and photodetectors. Methylammonium lead iodide (MAPbI3) is the perovskite most commonly used in solar technologies and one of the few perovskites that can be fabricated with standard production techniques. And yet, the solar...

In electronics production laser system solutions not only help make the production of printed circuit boards, semiconductors, OLED displays or solar panels more efficient. Many steps would not be possible without laser light in this precision and fineness of the structures. "Through ever shorter wavelengths, constantly increasing performance and compliance with extreme reliability requirements, state-of-the-art laser systems continuously push the limits of what is possible in electronics...

A doctoral student in the School of Architecture and Design at the University of Kansas (KU) has developed a low-tech yet adaptively adjustable daylighting solution that combines the benefits of automated controlled daylighting systems and the simplicity of static ones to enhance the distribution of natural light in an interior space.  From static to dynamic The effectiveness of traditional, fixed lightshelves is limited because they only perform optimally at the time of day when the...

Earlier this week, the office of the U.S. Trade Representative (ITC) announced that President Donald J. Trump had imposed additional duties on solar panels and solar cells. The additional tariffs are 30% on imported solar panels and cells, declining by 5% per year over four years, with an exemption for the first 2.5 gigawatts of imports. These tariffs are the result of the Section 201 trade petition by Suniva and SolarWorld, (two global solar module manufacturers with production in...
