Solar energy - Electricity Generation: Solar radiation may be converted directly into solar power (electricity) by solar cells, or photovoltaic cells. In such cells, a small electric voltage is generated when light strikes the junction between a metal and a semiconductor (such as silicon) or the junction between two different semiconductors.
New research suggests that there might be other ways to generate solar energy than just trying to make individual solar cells super-efficient. Scientists are always on the lookout for ways to make our world a better place, and one area they're focusing on is solar energy.
A solar cell is a device people can make that takes the energy of sunlight and converts it into electricity. How does a solar cell turn sunlight into electricity? In a crystal, the bonds [between silicon atoms] are made of electrons that are shared between all of the atoms of the crystal.
Scientists at Oxford University Physics Department have developed a revolutionary approach which could generate increasing amounts of solar electricity without the need for silicon-based solar panels.

Given the distribution of photons in sunlight—each with its distinctive wavelength and energy—even an ideal solar cell could turn only 34% of the total energy into electricity. One way to deal with that efficiency limit is to stack up layers of different semiconductors, each absorbing different colors of sunlight.
