Spacebound silicon Solar has a long history in powering satellites and space exploration, and high-powered devices based on multijunction PV cells made from “III-V” materials such as gallium arsenide or indium gallium phosphide have supplied this niche market as far back as the 1960s. But those devices are made with rare materials and complex processing, limited to small batches produced at high cost.

Digital twin tech offers ‘anti-involution’ strategies for China’s PV industry Researchers in China have developed a digital twin-based simulation framework to help PV manufacturers counter excessive price competition and declining profitability. The study found that combining moderate price increases with higher R&D investment could improve financial performance and long-term competitiveness, although the results remain unvalidated in real-world operations.

The case for railway-integrated solar in South Korea South Korea’s extensive railway network could provide new space for solar generation in densely populated areas where land availability is limited. Researchers have investigated the potential of installing PV systems between railway tracks, finding that suitable sections of five surface railway corridors could host more than 8.5 MW of solar capacity.
