That means that their efficiency _ 9 when you expose them to light-pretty much11 the worst possible effect12 for a solar cell, Pearce explains, which is one of the 10 thin-film solar panels make up only a small fraction of the market.

　　However, Pearce and his team found a way to engineer around13 the Staebler-Wronski effect by incorporating thin-film silicon in a new 11 of PVT. You dont have to cool down thin-film silicon to make it work. In fact, Pearces group discovered that by heating it to solar-thermal operating temperatures14, near the boiling 12 of water, they could make thicker cells that largely.

　　13 the Staebler-Wronski effect. When they applied the thin-film silicon directly to a solar thermal energy 14 , they also found that by baking the cell once a day, they ____15____ the solar cells electrical efficiency by over 10 percent.
