Scientists at Nanyang Technological University in Singapore (NTU) have developed a next-generation sunlight to electricity solar cell material which can also emit light. The solar cell is built from Perovskite, a promising material (also see this link) that could hold the key to creating high-efficiency, inexpensive solar cells. The new cells not only glow when [...]

University of Michigan (UM) researchers have invented colorful, see-through solar cells that may one day be used to make stained-glass windows, decorations and even shades that turn the sun’s energy into electricity.  The technology may also be a solution to photocell orientation to the sun problem. Jay Guo, a professor of electrical engineering and computer [...]

Researchers in China suggest micro-machining could be used to create almost flat Fresnel lenses that boost the electrical efficiency of solar panels.  Using Fresnel lenses to design solar panels could lead to fewer solar cells in a panel taking in the same area of light.  Such designs could be much less expensive. The team’s technology [...]

A new understanding of the basic science of charge separation offers new insight on making cheaper organic solar cells.  The researchers suggest improved design rules for making more efficient solar cells in the future. Penn State electrical engineer Noel Giebink with lead author Bethany Bernardo, an undergraduate in his group, and colleagues at IMEC in [...]

A new approach developed at MIT uses sunlight to heat a high-temperature material whose infrared radiation would then be collected by a conventional photovoltaic cell that could generate power from sunlight efficiently and on demand.  The MIT researchers expect the technique could also make it easier to store the energy for later use. The new [...]
