How surface recombination velocity at the junction interface affects the schottky junction solar cells transport?

It is generally known that a higher surface recombination velocity (SRV) tends to lower the device performance (e.g. Voc) due to a higher recombination at the metal and semiconductor interface....

Why drift current is independent of the bias voltage in a pn junction?

Can anyone explains that why drift current is independent of the bias voltage? I thought the drift current is dependent on the bias voltage. The drift current equation tells us that the drift...

Why Si surface is hydrophobic after cleaning with HF solution?

From what I know is after HF etching of the Si surface, the SiOx is removed and the surface is left with H-terminal on top of Si. Since H is more electronegative than Si, As a result H is negative...
