At the end of one of the hottest summers on record, as fights about how to power homes rage, renewable solar energy continues to present an option that does not significantly add greenhouse gases to the environment in exchange for lighting and cooling our homes. And it’s just been given another edge through material science.
In a new study published in Energies, researchers have found a way to reduce production costs of solar cells by more than 10 percent.
“Improving cost per unit power at the cell level can have massive effects downstream,” says Joshua Pearce, professor of material sciences and electrical engineering at Michigan Tech. Already, he says, costs of solar energy are comparable to conventional forms of electricity and is the fastest growing energy source. This 10 percent drop should push solar to the forefront even faster.
