Abstract: The charge transfer and photoelectric properties of porous silicon were investigat-ed by photoelectrochemical techniques.The results show that the porous silicon fabricated bysingle crystalline p-Si exhibits photoelectric properties of p-type semiconductors with a high-er photocurrent than the original silicon.Due to the unique surface structure, the porous sili-con has a particular photocurrent spectrum.This is attributed to the photocharge-trappingeffect of surface states in the porous silicon.

Key words: Porous silicon, Photocurrent, Photoelectrochemistry, Charge transfer
