Paper Abstract

The idea of the quantum dot solar cell, which provides a novel direction to the high-efficiency solar cell problem, is developed. A theoretical model is presented for a practical p-i-n quantum dot solar cell built on the base of the self-organized InAs/GaAs system. Study the advantages of the use of quantum dots in active region for photon absorption in the long-wavelength part of spectrum and increase in the efficiency of the conversion of solar energy in electrical power is carried out. Problems of theory and experiment of low-dimensional solar cells (quantum well and quantum dot solar cells) are discussed.
