近日，第42届欧洲光伏太阳能会议及展览在西班牙毕尔巴鄂开幕。作为世界领先的光伏研究论坛和 最大的光伏太阳能展会，今年，来自全球各国的近60家参展商，集中展示了光伏行业最前沿的成果与思 路，并为太阳能技术领域及其他能源1800位专家提供了一个国际太阳能领先技术交流平台。 在这一背景下，中欧双方在光伏科研、标准、可持续发展等层面开展合作。过去十多年，中国企业 的规模化生产显著拉低了光伏成本，让"昂贵"的太阳能在各国可及。欧洲一方面希望通过政策鼓励更多 本土制造和创新，以增强供应链韧性；另一方面，它清楚技术落地和市场普及仍离不开中国的支持。 轻薄、柔性、半透明……中国企业鹑火光电在展会现场，展示了其最新的钙钛矿太阳能电池整线制 造设备解决方案。作为一种新型的太阳能电池类型，钙钛矿具有优异的光电转换效率。与传统的硅基太 阳能电池相比，钙钛矿电池具有更高的光吸收能力和更低的制造成本潜力。 中国企业鹑火光电工作人员向欧美客户展示该企业研发制造的钙钛矿电池。人民网记者 颜欢摄 鹑火光电首席技术官马跃告诉记者，在光伏行业，效率与成本是永恒的命题。钙钛矿电池在效率、 成本方面都有大幅提升潜力，且它的物理特性允许更广阔的应用场景 ...

Core Viewpoint - A new fully organic solar cell developed by Kanazawa University and Queen's University has achieved a record power conversion efficiency of 8.7%, more than doubling the previous record, paving the way for the practical application of environmentally friendly solar cells [1][2] Group 1: Technology and Innovation - Traditional silicon-based solar cells have high efficiency but pose environmental burdens due to harmful substances, while perovskite solar cells raise concerns due to lead compounds [1] - Fully organic solar cells, made entirely from carbon-based materials, can be safely disposed of after use, significantly reducing environmental costs [1] - Previous efficiency of fully organic solar cells was only 4%, far below silicon (27%) and perovskite (26%) solar cells, primarily due to two technical bottlenecks: the need for strong acids, bases, or high-temperature annealing in the preparation of conductive organic electrodes, and damage to lower layer structures during multi-layer stacking processes [1] Group 2: Breakthroughs and Future Prospects - The research team employed a "gentle process" to overcome these challenges, developing a transparent electrode based on the conductive polymer PEDOT:PSS, which can be prepared at 80°C without acids or bases [2] - They also introduced a carbon nanotube electrode lamination technique, forming electrodes on the solar cell barrier film and attaching them to the device, preventing damage to the underlying organic films during electrode manufacturing [2] - This combination of innovations has led to a significant increase in the efficiency of fully organic solar cells to 8.7%, marking a crucial step towards the practical application of high-performance fully organic solar cells [2] - Future applications for fully organic solar cells are expected in environmentally sensitive areas such as farmland and wearable devices, leveraging their lightweight and flexible characteristics [2]
