Cheap solar panels made from amorphous silicon (instead of the more expensive, yet more commonly used crystalline silicon) will now be more efficient. Researchers at TU Delft have discovered a way to increase the efficiency of these less-expensive solar panels from 7% to 9%. Even though its very cost-effective to produce amorphous solar panels with [...]
It is such a basic idea, it is surprising that someone didn’t point this out earlier. The gorgeous, deep-blue PV panels that gleam in the sunlight can be a lot more efficient if they were a less reflective. Of course! Just think that when the light bouncing off solar panels is absorbed instead, dull solar [...]
