| 总结: | The paper examines the issues of solar cells designs based on new LPE GaAs epitaxial structures for high-efficiency reception and conversion of solar energy in the wavelength band λ = 0,2 ÷ 4,0 μm, which allows to use them both under extreme climatic conditions of Sahara desert and in Baltic Sea region.The paper shows future promising power devices for DC/AC conversion of solar energy to single-phase and three-phase power at frequencies 2 ÷ 10 MHz and with maximum ambient/case operating temperature up to 250°C.The paper addresses challenges and opportunities for development of new-generation high-performance LPE GaAs photodetectors on the basis of the new physical principles:-effect of GaAs energy band gap splitting by amphoteric hydrogen-like centers on silicon (Si) atoms;-phenomenon of efficiency increase in photodetectors based on quantum dot magnetic centers |
