Chinese researchers have found that perovskite solar cells (PSC) can retain most of their power conversion efficiency in near space, providing perspectives on the new solar cells' future application in space. Chinese researchers sent PSC test parts into near space on a high-altitude balloon in China's Inner Mongolia region. The balloon rose to near space at an altitude of 35 km. According to the findings, one type of perovskite solar cells used in the study retained more than 95 percent of its initial power conversion efficiency during the test.
