Photovoltaic solar cells convert light energy from the sun into electricity. Although significant strides have been made in increasing the efficiency of photovoltaic technology, they usually only result in incremental increases. Researchers at Stanford University have come up with a way that could more than double the efficiency of existing solar cell technology and potentially reduce the costs of solar energy production enough for it to compete with oil as an energy source. Instead of relying solely on photons, the new process, called “photon enhanced thermionic emission,” or PETE, simultaneously combines the light and heat of solar radiation to generate electricity...
