Yanhe Technology launched three independently developed space photovoltaic modules into a 535 km sun-synchronous orbit on Nov. 7, pv-magazine.com reports. The rocket was Galactic Energy's Ceres-2 Y3, launched from the Jiuquan Satellite Launch Center [1]. The company described the mission as China's first simultaneous in-orbit validation of three perovskite-based PV technologies [1].

## Modules and test conditions

Two tandem modules, a perovskite-crystalline silicon device and a perovskite-CIGS device, are installed on the North University of China-1 satellite [1]. The spacecraft operates in a dawn-dusk orbit, where near-continuous sunlight places demanding requirements on power density and long-term stability [1].

A flexible single-junction perovskite module is installed on the Yunyao-1 28 satellite [1]. It will undergo imaging during thermal cycling and performance monitoring to assess degradation caused by particle radiation and atomic oxygen exposure [1].

Yanhe has not disclosed the conversion efficiencies, rated power outputs, active areas or weights of the three modules [1]. The company's announcement and independent industry reports confirmed the launch, the satellite platforms and the orbital altitude [1].

Chief Technology Officer Peng Zongyang said the perovskite-silicon and perovskite-CIGS tandem architectures target different segments of the space PV market [1]. According to him, the mission aims to evaluate the efficiency and stability of both under actual orbital conditions [1]. The company is also assessing the fully thin-film perovskite-CIGS tandem for potential advantages in flexibility and radiation resistance over silicon-based tandems [1].

## Earlier tests and open questions

In September, Yanhe deployed a flexible perovskite module aboard the Tianyi-52 satellite for long-term performance monitoring [1]. The company called it China's first component-level in-orbit test of flexible perovskite PV technology [1]. In October, it set up a joint laboratory with the Hong Kong University of Science and Technology for research on perovskite solar cells, space photovoltaics, orbital energy systems and flexible devices [1].

Perovskite cells have drawn interest for space because of their potential for high specific power and lower material costs than the III-V gallium arsenide cells commonly used in satellite power systems [1]. Yanhe is targeting the growing low Earth orbit constellation market, where lighter modules could reduce launch costs [1].

Maintaining performance under prolonged radiation and repeated thermal cycling remains a key technical challenge for perovskite modules [1]. The mission is expected to produce comparative in-orbit data for the three architectures [1]. Yanhe has not specified the duration of the monitoring campaign or the amount of telemetry expected [1].
