Today's Quick News Digest (CEFR B1)
Scientists have announced a historic breakthrough in renewable energy technology. A new type of solar cell has reached an unprecedented efficiency rate of over 34 percent during controlled laboratory testing. The majority of conventional solar panels used worldwide are constructed from standard silicon, which typically transforms only about 20 to 22 percent of incoming sunlight into usable electricity.
