摘要：

The photoelectrochemical behavior of electrochemically etched Si cathodes contacting a nonaqueous redox electrolyte is described. The electrochemically etched Si electrodes exhibit higher energy conversion efficiencies than Si electrodes chemically treated in HF solution. The porous Si layer formed during electrochemical etching plays an important role in suppressing surface recombination and stabilizing the Si electrodes against photocorrosion.
