The concept of ‘Space-based Solar Power’ (SBSP) has recently gained significant attention in the energy and aerospace sectors. It involves deploying solar photovoltaic systems in space to harness solar energy efficiently, leveraging advantages such as the absence of atmospheric obstruction and nearly continuous sunlight. The collected energy would be transmitted wirelessly to Earth (e.g., via microwaves or lasers) for use. This approach aims to overcome limitations of terrestrial solar power, including昼夜 cycles, weather conditions, and latitude constraints, potentially providing stable and highly efficient clean energy.Currently, the technology remains in early research stages, facing challenges such as high costs, wireless energy transmission efficiency, adaptability to the space environment, and safety concerns. Multiple aerospace organizations and companies worldwide, including China Aerospace Science and Technology Corporation (with its ‘Zhuri Project’), are conducting related experiments. Industry experts note that while space-based solar power represents a promising future energy direction, commercialization will require long-term investment and cross-disciplinary collaboration, with short-term efforts focused on technological development and validation.
“太空光伏”概念近期在能源与航天领域引发广泛关注，指通过将太阳能光伏发电系统部署于太空，利用宇宙环境无大气遮挡、近乎持续光照等优势，实现高效收集太阳能并通过无线传输技术（如微波或激光）传回地面使用。这一构想旨在突破地面光伏发电受昼夜、天气及纬度限制的瓶颈，有望提供稳定、高效的清洁能源。目前，该技术仍处于早期研究阶段，面临成本高昂、无线能量传输效率、太空环境适应性及安全性等挑战。国内外多家航天机构与企业正开展相关试验，如中国航天科技集团已提出‘逐日工程’探索计划。业内专家表示，太空光伏是未来能源的重要方向，但商业化需长期投入与跨领域协作，短期内仍以技术积累与验证为主。
