Space applications

With the transition from government-led “Old Space” to privately driven “New Space,” space development has evolved from military-focused competition among major powers into a commercial domain where private entities drive innovation, explore new markets, and generate economic value. Solar photovoltaic panels, which convert sunlight into electrical energy, are a core technology for space vehicles. However, current commercial III–V semiconductor-based photovoltaic cells rely entirely on imports due to the lack of domestic source and manufacturing technologies.

The space environment represents one of the most extreme conditions encountered by humanity. Compared to terrestrial operation, photovoltaic devices in space are exposed to intense solar irradiance, high vacuum, extreme temperatures, and ionizing radiation. Therefore, the development of novel photovoltaic materials and device architectures with high durability under such conditions is essential.Our laboratory develops optoelectronic devices for space applications by leveraging a uniquely designed space-environment-simulated photovoltaic characterization platform, along with strong domestic and international research collaborations.
