High-efficiency solar cells have been fabricated thanks to a new method for adding molecules of an organic compound during fabrication.
Conventional solar cells are based on silicon and have a maximum efficiency of about 25%. But a new kind of solar cell based on crystals known as perovskites have been achieving efficiencies rivalling those of silicon solar cells.
However, one hindrance to fabricating high-efficiency perovskite solar cells is realizing controlled doping of the perovskite material.
Now, a team led by researchers from SUSTech in Shenzhen, China, has developed a new molecular doping process, and they used it to achieve a record conversion efficiency of 25.4% in a perovskite.
The device showed good stability, with its conversion efficiency dropping by just 3.4% after 1,000 hours of exposure to light.
