University of Queensland researchers have developed indoor solar panels that could one day power your wearables, sensors, and small electronics using nothing but the light already in your home or office.
The panels are based on perovskite, a material that has been gaining attention as a successor to traditional silicon in solar cells. While silicon-based indoor solar cells top out at around 10 percent efficiency, perovskite can do significantly better.

The catch has always been that most perovskite solar cells rely on lead and hazardous solvents in their production, which is a problem for both safety and scaling up to real-world manufacturing. The UQ team has figured out a way around that.
So how does it actually work?
PhD student Zitong Wang, under the supervision of Dr Miaoqiang Lyu and Professor Lianzhou Wang, developed a vapor-based process that can manufacture high-quality lead-free perovskite material without
