See Through Cells

These solar cells are commonly known as solar panels, and are known to require a lot of material and is very heavy for just one solar panel. This year, Richard Lunt and his team of researchers have created a new type of solar panel, one that uses less resources and is more convenient looking. They have created a window solar panel that's as efficient as the normal panels. If this panel is use around our homes, then our electricity bills will decline drastically, we would even stop relying on oil and the gas prices that are currently rising.
