Sharp Corp. announced a semi-transparent black architectural glass panel that has built-in photovoltaic generation (aka solar power) capabilities. The panel is 4.5-ft. x 3.2ft -- about the size of a glass coffee table. It is a slender 0.37 in. thick. The panel is laminated glass infused with semi-transparent thin film solar cells. The cells both generate power and act as a natural insulator serving as a heat barrier. Plus their black color could offer an extra degree of privacy to residents in buildings with the panels. The panel can produce up to 95 watts at 6.8 percent efficiency.
