Russian, Italian Scientists Create High Power Conversion Solar Panels for Internet of Things

Scientists from the National University of Science and Technology “MISiS” (NUST MISIS) in cooperation with their Italian colleagues have proposed a new type of photovoltaic energy cells to power equipment with solar and household light.

According to the authors, photovoltaic cells would be capable of powering the Internet of Things (IoT) devices, fitness trackers, smartwatches, and headphones.

The rapidly growing market for wireless devices and IoT sensors requires autonomous energy sources with low power consumption and a power output of about one microwatt, the researchers claim. One such solution is compact perovskite photovoltaic cells that can provide energy reserves even when charged by standard indoor lighting fixtures.

Perovskites are a class of minerals with a pseudo-cubic crystal structure and a number of unique properties that are actively used in the energy industry. Perovskite photovoltaics have an efficiency of about 25 percent, which is comparable to semiconductors, but they are much easier to manufacture.
