英文摘要： Thermophotovoltaic, converting infrared thermal irradiation into electricity by photovoltaic cell, has been regarded as an important strategy of the third generation photovoltaic technologies to conquer energy crisis. Under the suggested project, by analyzing deeply the origin of low efficiency dilemma suffered by current thermophotovoltaic, we will theoretically investigate the novel methods to enhance thermophotovoltaic system performance in the framework of thermal irradiation management. Firstly, on the basis of the antimony-based alloy semiconductors with lattice 6.1 angstrom, we will systematically study the intrinsic relationship between device structure performance and external thermal irradiation spectrum, revealing the impaction of various technical parameters on cell performance and establishing further the fundamental principle to construct new device structure of high performance-price ratio. Secondly, still based on the antimony-based alloy semiconductors, by investigating the theoretical relationship among bandgap combination, device structure, thermal irradiation spectrum, and performance output, we will establish novel strategies to enlarge the cut-off wavelength of cell spectrum response and construct new multiple-bandgap cell for high efficiency but low cost thermophotovoltaic applications.
