| 英文摘要 | a novel concept for solar electricity generation named photon-enhanced thermionic emission (pete) was recently proposed for harvesting solar photonic and thermionic energies simultaneously. comparative investigations showed that the conversion efficiency of pete can theoretically exceed 40%. in this paper, an electric field-assisted pete experiment was carried out to demonstrate the possibility of using gaas epitaxial films in pete solar devices. the solar photonic and thermionic effects were simulated by a red light-emitting diode array and a heat resistor, respectively. surface electron affinity was decreased by an electric field instead of cs/cs-o coating. the experimental results agreed with calculated values, and a distinct enhancement was observed in the thermionic emission produced by photoexcitation compared with thermionic field emission produced by an illuminated sample and the sample emission obtained in the dark.
