The latest episode in the American Chemical Society's (ACS) award-winning "Global Challenges/Chemistry Solutions" podcast series features a new solar cell with high efficiency in converting sunlight into electricity and the durability to last and last. In the podcast, Michael Graetzel, Ph.D., describes research that aimed to develop an improved version of a highly promising solar cell that is less expensive than conventional solar cells made from the semi-conductor material, silicon. These...

A new twist on an old solar cell design sends light ricocheting through layers of microscopic spheres, increasing its electricity-generating potential by 26 percent. By engineering alternating layers of nanometer and micrometer particles, a team of engineers from the University of Minnesota has improved the efficiency of a type of solar cell by as much as 26 percent. These cells, known as dye-sensitized solar cells (DSSC), are made of titanium dioxide (TiO2), a photosensitive material that is...

MIT reported on Monday that researchers have a used genetically modified virus to produce structures that improve solar-cell efficiency by about one-third. MIT researchers said they have found a way to make significant improvements to the power-conversion efficiency of solar cells by using a tiny virus to perform detailed assembly work at the microscopic level. Sunlight hits a light-harvesting material in a solar cell, which releases electrons that can produce an electric current. ...
