Since eBook Reader is a very hot topic right now, LG Displays decided to show off their new thin-film solar cell in an eBook Reader.
The thin-film solar cell featured in the e-book measures 100mm in width and length, it was developed to fit the 6-inch display panel for e-books currently mass produced by LG Display. The solar cell measures 0.7mm in thickness and weighs a mere 20g.
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.
The current energy conversion efficiency rate of this product is approximately 9.6 percent. Exposure to sunlight for about four to five hours would extend the running time of the e-book’s battery by a day without the need for additional charging.
