The future can be expected! Perovskite and organic solar cells have been successfully tested in space for the first time. They are thinner and cheaper than silicon.

according to Joule, an internationally renowned academic journal, perovskite and organic solar cells have been proved to be promising substitutes for widely used silicon-based devices, and now they have been tested in space for the first time. The test results of the Technical University of Munich (tum) show that these solar cells not only have good performance, but also are thinner and lighter than the batteries currently used, and can even absorb the diffuse light reflected from the earth

for decades, silicon has been the preferred material for solar cells, and so far, it provides good performance. However, it may soon be replaced by perovskite, which has developed rapidly in the past decade or so, and its efficiency is close to that of silicon

in addition, organic solar cells are another increasingly attractive option. In terms of efficiency, they may not be able to compete with silicon, but their advantages are thinner, more flexible, and much lower mass production costs

it is reported that perovskite and organic solar cells have recently been tested in space for the first time. In a new study by researchers at the Technical University of Munich (tum), they connected two models of each type of solar cell to a sounding rocket launched from northern Sweden, which carried out a short suborbital round trip at an altitude of up to 240 kilometers (149 miles)

the results showed that the solar cells withstood the extreme conditions of launch and flight, and successfully collected sunlight in space within 7 minutes. They may not be as efficient as silicon, but they are much smaller. In space flight, size and weight need to be kept to a minimum

Peter M ü ller buschbaum, the senior author of this study, said, "in this industry, the important thing is not the efficiency, but the electric energy generated by the unit weight, that is, the so-called specific power. When the height of the rocket flying over the oil surface is less than 2/3 of the cylinder depth, it should be replaced immediately. During the process, the power of this new solar cell reaches 7 to 14 milliwatts per square centimeter."

what's more interesting is that these solar cells can absorb energy even when they are far away from the sun. They seem to be able to capture the weak light reflected from the earth's surface, which traditional solar cells usually cannot do

"this is a good hint, and it also confirms this technology. Look at which model of experimental aircraft is suitable for your ordinary operation. It can be used for the so-called deep space missions, that is, to send them to space far away from the sun, where standard solar cells cannot work. The future of this kind of technology is very exciting, and they can be used for more space missions in the future." M ü ller buschbaum said

of course, the seven minute space test is not long, so researchers hope to test perovskite and organic solar cells on satellites in the future
