Editorial
Keep conditions right for invention High achievement always takes place in the framework of high expectation. – Charles F. Kettering, inventor of the electric starter Contemplating the many contributions of Elias Snitzer, whose pioneering work in glass lasers helped bring about a communications revolution, made me wonder about the atmosphere prevalent in his day that supported such discovery. Were expectations high? Was...

LED-like solar cell absorbs, emits light A new solar cell designed to be more like an LED, able to emit light as well as absorb it, could achieve efficiencies close to 30 percent. Typical solar cells theoretically can harvest about 33.5 percent of energy from sunlight, but scientists have yet to reach this efficiency. Since 1961, scientists have known that, under ideal conditions, solar cells at most will absorb and convert 33.5 percent...
