Today’s solar cells – which are typically silicon-based – can convert an average of around 22% of the sunshine they absorb into power. More efficient solar cells mean each solar panel can generate more electricity, saving on materials and the land needed. Manufacturing silicon solar cells is also an energy-intensive process.

His device wasn’t very efficient – it was only capable of turning a tiny amount of the sunshine it absorbed into electricity, about 1% to 2%. Today’s solar cells – which are typically silicon-based – can convert an average of around 22% of the sunshine they absorb into power.
“The way to think of it is that the solar cell is like a single battery and the way it works is - it absorbs some of the sun's light and miraculously, with just the silicon material, it can turn that sunlight into electricity,” she explained. “There are gaps in that sunlight that silicon can't access.
However, has shown that future solar panels could reach efficiencies as high as 34% by exploiting a new technology called tandem solar cells. The research demonstrates a record power conversion efficiency for tandem solar cells. What are tandem solar cells? Traditional solar cells are made using a single material to absorb sunlight.
NASA is also developing technology for flexible and rollable solar panels that can improve their use in constrained spaces. Using different materials for the base layer of a solar panel can make a panel lighter and more flexible — essential attributes for space missions that need to be packed into a small space in a rocket.
