LG introduces an e-book reader that is equipped with a slim solar cell developed by LG. The thin-film solar cell measures 10cmx10cm that perfectly fit the 6-inch e-book display panel.
The thin-film solar cell is produced by placing electrodes onto a glass or plastic substrate. Contrary to widely adopted crystalline solar cells that employ silicon wafers, the thin-film solar cell is generally light-weight and easily adjustable in size and form for applications such as e-books or mobile phones.
