We introduce a novel series connection technique to fabricate small photovoltaic modules by layer transfer. Using the porous Si (PSI) process and the novel technique, we fabricate a monocrystalline Si solar module that consists of five series‐connected cells with an effective film thickness of 16 μm and an independently confirmed power conversion efficiency of 10.6%. The module size is 5 × 5 cm 2 . The effective thickness is equal to the film volume divided by the film area. The cells have a back surface texture of random inverted pyramids. The process avoids photolithography. Copyright © 2001 John Wiley & Sons, Ltd.
