BEIJING, China (PNN) - September 17, 2019 - Swedish and Chinese scientists have developed a new kind of organic solar cell that has been optimized to convert ambient indoor light into electricity.

The power they produce is low, but is probably enough to feed the millions of products that the Internet of things will bring online.

As the Internet of things expands, it is expected that we will need to have millions of products online, both in public spaces and in homes. Many of these will be the multitude of sensors to detect and measure moisture, particle concentrations, temperature and other parameters. For this reason, the demand for small and cheap sources of renewable energy is increasing rapidly, in order to reduce the need for frequent and expensive battery replacements.
