Researcher identifies defects in solar cells made of silicon

Since he was a teenager, engineer Sergio Castellanos had the desire to study abroad to prepare and do research in the best laboratories, particularly on solar energy. With six years of study in the United States, first at ...

Detecting defects in solar cells

Scientists at the National Physical Laboratory (NPL) have developed a new method for detecting defects in solar cells using a technique called 'compressed sensing'.

Carbon-based nanomaterials could lower cost of solar energy

When Mike Arnold thinks about solar energy, he thinks big, as in the "more than one-hundred-million-billion watts of sunlight that the Earth continuously bathes in." But he also thinks very, very small, exploring how a one-billionth-of-a-meter ...

Team grows uniform nanowires

A researcher from Missouri University of Science and Technology has developed a new way to grow nanowire arrays with a determined diameter, length and uniform consistency. This approach to growing nanomaterials will improve ...

New solar cells serve free lunch

One of the most common complaints about solar power is solar panels are still too expensive to be worth the investment. Many researchers have responded by making solar cells, the tile-like components of solar panels that ...

Yale engineer to build 'hot' solar cells

Associate professor of electrical engineering Minjoo Larry Lee has been awarded $2,540,000 to develop dual-junction solar cells that can operate efficiently at extreme temperatures above 750 degrees Fahrenheit. In addition ...
