See-Through Solar Panels / Solar Windows From Sharp.

Sharp Solar Windows.  See-Through Solar Panels.Sharp Corporation is not the first to develop see-through solar panels but with their name recognition and ability to take advantage of economies of scale, hopefully they’ll be the most successful. Sharp’s semi-transparent solar panels are 4.5′ x 3.2′, 0.37-inches thin and have a solar efficiency of 6.8 percent. Their solar efficiency rating is low compared to standard opaque solar panels, that are in the 12-18% range, but these are windows and allow for solar power to be generated where rooftop solar may not be adequate or possible.

In addition to generating electricity, Sharp’s see-through solar panels will absorb a portion of the sunlight before it enters a room and in turn, reduce cooling costs. Now if Sharp can keep the price competitive, they may have a winner. [Crave]

Jubwinked? New Energy Technologies Inc.’s SolarWindow Uses Spray-On Solar Cells

New Energy Technologies SolarWindowOnce again, I hope New Energy Technologies is legit but I can’t help feeling Jubwinked again by a company with a technology that promises too much. New Energy Technologies just issued a press release about their spray-on-window solar cells that can outperform rooftop solar panels by 300%. When applied, the see-through SolarWindow technology will absorb sunlight entering the building as well as internal office lighting. According to New Energy Technologies, the SolarWindow “is made possible by spraying an electricity-generating coating on to glass at room temperature.” Conventional solar panel manufacturing requires high-heat in order to apply the the solar cells onto a opaque substrate and can not be transparent.

New Energy Technologies other product is MotionPower. MotionPower is basically a “speed bump” that generates electricity from the excess energy produced by moving cars and trucks passing over them. Here is a video that describes how the idea works:
