We have fabricated a textured monocrystalline Si solar cell with a thickness of 15·5 μm and a confirmed efficiency of 12·2% using porous silicon (PSI) for layer transfer. The PSI process avoids photolithography and high‐temperature oxidation. The cell has a surface that is textured with randomly positioned inverted pyramids for light trapping. The device does not yet fully exploit the light‐trapping capability of this film shape, owing to a small back‐surface reflectance. Copyright © 2001 John Wiley & Sons, Ltd.
