The research activities include determination of the basic mechanisms that control and limit solar-cell efficiency, engineering design of solar cells, and the improvement of cell design to increase the power conversion efficiency and to define the maximum efficiency expected from a given material technology. Experimental methods for determining the basic mechanisms in the highly-doped emitter region and for determining diffusion length and lifetime in the base region of p-n junction solar cells are discussed. The evolution of three different silicon solar cell structures proposed to yield efficiencies greater than 20% for illumination levels in the 25 to 100 sun range is discussed.
