SUPERSTRUCTURES AND MULTIJUNCTION CELLS FOR HIGH EFFICIENCY ENERGY CONVERSION.

Research output: Contribution to journalConference article

Abstract

Potential applications of superlattices to photovoltaic structures are discussed. A single-bandgap, multijunction cell with selective electrodes for lateral transport of collected carriers is proposed. The concept is based on similar doping superlattice (NIPI) structures. Computer simulations show that by reducing bulk recombination losses, the spectral response of such cells is enhanced, particularly for poor quality materials with short diffusion lengths. Dark-current contributions of additional junctions result in a tradeoff between short-circuit current and open-circuit voltage as the number of layers is increased. One or two extra junctions appears to be optimal.
