文摘
- •
The combination of thermionic and photoelectric emission for solar energy conversion was studied, including HEC and PETE.
- •
An experimental set-up with a NaCsSb photodiode was applied for the conversion of light to electric energy.
- •
A conversion efficiency of 1.97×10-2% at 20℃ was gained and a double enhancement observed with the temperature rising to 70℃.
- •
A new concept , thermally enhanced external photoelectric emission (TEPE), was presented for solar energy conversion.
- •
Essential differences among these three mechanisms (HEC, PETE, TEPE) were discussed.
