Thin‐film silicon solar cells are promising candidates for meeting the requirements of high efficiency combined with low cost. We use liquid‐phase epitaxy to grow thin silicon films on highly doped substrates. A solar cell made on this material has been measured independently to have an efficiency of 17.0%. an important step in obtaining these high cell efficiencies is the removal of most of the heavily doped substrate on which the epitaxial layer is grown.
