Source sentences:
text: The cells are very thin and fragile so they are sandwiched between a transparent front sheet, usually glass, and a backing sheet, usually glass or a type of tough plastic.
text: A solar cell is a sandwich or thin semiconductor wafer of two different layers of silicon (n-type silicon (blue) and p-type silicon (red)) that have been specially treated or doped so they will let electricity flow through them in a particular way.
text: Because charge carriers have diffusion lengths of just 3–10 nm in typical amorphous organic semiconductors, planar cells must be thin, but the thin cells absorb light less well.
