You knew it was coming, it just made too much sense the Solar ebook reader is on it’s way from LG. Demonstrating an ebook sized thin film solar cell on a Sony reader at the International Meeting on Information Display in Seoul, LG looks to solving one of the key constraints on ebooks. 
Ebooks are very handy, loads of books in one form factor, until the battery runs out. This solar cell is designed to extend battery life of the ebook. Measuring 100×100 mm and at a thickness of 0.7mm it is pretty compact. LG claims the cell currently has an efficiency rate of just 9.6 percent, but is aiming to steadily increase this over time to prepare for commercial application.
Even if an LG e-reader never come to market, the company will likely licence the technology to existing manufacturers keen on extending battery life.
Of course with the advances in Nuclear batteries this is a good time for micro device power.
