Australia's solar researchers have converted over 40 percent of the sunlight hitting a solar system into electricity, the highest efficiency ever reported. A key part of the prototype's design is the use of a custom optical bandpass filter to capture sunlight that is normally wasted by commercial solar cells on towers and convert it to electricity at a higher efficiency than the solar cells themselves ever could.

In world first, researchers convert sunlight to electricity with over 40 percent efficiency
We can hope that as solar continues to make strides in greater efficiency, dependence on fossil fuels will become less and less something that is a major aspect of our geopolitics.
