[en] We have attempted to justify the appropriateness of the photoelectric and thermoelectric (photothermoelectric) cells in the development of efficient thermophotovoltaic systems and facilities with photoelectric converters and concentrators of solar radiation. These cells are p-n structures based on narrow-band semiconductors capable of the simultaneous thermo- and photogeneration of electron-hole pairs under the effects of irradiation. We discuss the reduction of losses in the course energy conversion carried out with a photothermo-electric cell instead of separate thermo- and photoelectric cells. In addition, we describe the characteristic features and estimate the efficiency of photothermoelectric cells in the thermophotoelectric systems and facilities for the photoelectric conversion of the concentrated solar radiation.

[en] We have studied the peculiarities of the extrinsic thermal voltaic effect and the possibility of reducing the optimal temperature for using photothermal elements and selecting the impurities for conducting preliminary experimental surveys on this subject. (author)

[en] Using an energy band diagram, the action of a thermocell is considered and the approximate values of its volumetric and barrier electromotive force are determined. A solar thermocell with low-bandgap photo-heated layers, which performs conversion between radiant and electric energy, is proposed. An approximate estimate of its limiting efficiency is given.

[en] The paper proposes a method of increasing the efficiency of Si and CuInSe2 solar cells using the impact ionization and impurity photovoltaic effect in pZnTe-pSi-nSi and pZnTe-pCuInSe2-n(CuInSe2)1-x(2InAs)x structures. (author)
