UCLA breakthrough could lead to more durable, less expensive solar cells

UCLA researchers has developed a way to use perovskite in solar cells while protecting it from the conditions that cause it to deteriorate.

Using enhanced halide perovskite in place of silicon could produce less expensive devices that stand up better to light, heat.

Amid all of the efforts to convert the nation’s energy supply to renewable sources, solar power still accounts for a little less than 3% of electricity generated in the U.S. In part, that’s because of the relatively high cost to produce solar cells.

One way to lower the cost of production would be to develop solar cells that use less-expensive materials than today’s silicon-based models. To achieve that, some engineers have zeroed in on halide perovskite, a type of human-made material with repeating crystals shaped like cubes.
