China Photovoltaic Industry Association: Space photovoltaic technology is still in the early stage of exploration and verification.

Currently, space photovoltaic technology is still in the early stages of exploration and validation, and it is too early to determine a clear technological direction," said Liu Yiyang, Executive Secretary of the China Photovoltaic Industry Association on February 4. In the past two days, driven by research news from the Musk team, the concept of space photovoltaics has once again ignited the market. Liu Yiyang said that the concept of space photovoltaics has indeed "taken off", causing a stir in the capital market and the technology sector. In the A-share photovoltaic sector, concept stocks have been continuously hitting the daily limit, and many brokerage research reports believe that heterojunction and perovskite technologies are suitable for application in the space field. These research reports are mutually reinforcing, triggering unprecedented volatility in the capital market; domestic companies have also expressed their intentions to enter the market, throwing around topics such as "trillion-dollar blue ocean" and the "next photovoltaic revolution." However, he emphasized that regardless of how any technology evolves, truly reaching commercialization cannot be achieved without a mature, replicable high-efficiency manufacturing capability and a long-term reliability verification system. According to analysis by the China Photovoltaic Industry Association, in terms of practical application, gallium arsenide batteries are still the mainstream choice for commercial aerospace and space stations due to their high conversion efficiency and excellent radiation resistance, despite their high cost. Although the cost is high, after long-term on-orbit verification, their reliability is high. In contrast, the heterojunction perovskite technology that the capital market is currently enthusiastic about is more based on the "cost reduction logic" proposed by individual financial institutions. In reality, the actual products are still in the laboratory or validation stage, and are still far from large-scale commercialization.
