Scientists launch first satellite mission to test perovskite tandem solar cells

Exciting developments are underway with a new solar panel material known as perovskite tandem solar cells, currently being tested in space! According to PV Magazine, under the leadership of Dr. Felix Lang from the University of Potsdam, a collaborative team including researchers from Helmholtz-Zentrum Berlin and the Technical University of Berlin has launched two types of these innovative cells on their inaugural satellite missions. They are assessing their durability and performance, with additional tests being conducted at the International Space Station. Following a successful launch in July, the initial results are promising.

The remarkable advantage of perovskite technology lies in its potential to significantly enhance the efficiency of solar panels. While traditional panels convert 20% to 25% of incoming sunlight into electricity, perovskite models can achieve impressive efficiencies of 35% to 45%, according to PV Magazine.

Although there were initial concerns regarding the durability of perovskite—specifically if it might sacrifice longevity for efficiency—the current mission is dedicated to evaluating how these tandem solar cells withstand the extreme conditions of space, located 580 miles above Earth, where they face radiation and extreme temperature fluctuations.

As PV Magazine highlights, two types of cells have been selected for these tests: perovskite/CIGS and perovskite-silicon tandem cells. Perovskite captures the blue-to-green wavelengths of sunlight, while CIGS or silicon absorbs red and infrared radiation.

Dr. Lang has shared the uplifting news that the satellite has already begun transmitting signals indicating that the equipment is functioning well, even though the solar panels have not yet aligned with the sun.

These early results are encouraging! Dr. Lang is not only hopeful for improved efficiency but also anticipates that perovskite may exhibit self-healing properties, able to repair some damage caused by solar radiation. This capability could extend its lifespan, making perovskite a fantastic alternative to conventional solar panels.

As the mission unfolds, the team looks forward to receiving ongoing updates, which will provide valuable insights into the performance of this groundbreaking new material. The future of solar energy is bright!
