BC 电池是一种将太阳电池的发射极、背场、基区、发射极电极和背场电极均设计在电池背表面的高效率硅基太阳电池。IBC 电池将栅线做到背面，避免金属栅线电极对太阳光线的遮挡，能够最大限度地利用入射光，减少光学损失。BC 电池作为平台型技术，可与 P 型、HJT、TOPCon 等技术结合，形成 HPBC、HBC、TBC 等电池结构，从而更好的发挥各类型电池的优点。

2月20日，阿里巴巴发布2025财年第三季度财报，公司云计算业务表现亮眼，收入同比增长13%，AI相关产品收入连续第六个季度实现三位数增长；截至2024年12月31日的三个月资本开支为318亿元，环比+80。阿里巴巴CEO吴泳铭明确表示，通用人工智能(AGI)将是公司AI战略的核心。在未来三年内，阿里巴巴计划在AI基础设施、基础模型和AI业务转型三个领域进行重点投资，其中未来三年在云和AI的基础设施投入预计将超越过去十年的总和（约3800亿元），即未来每年投入在1300亿元左右。AI应用迎来拐点，字节跳动、腾讯、阿里巴巴等互联网企业加大基建投入力度。

数据中心对供电稳定性的要求极为严苛。数据中心电能质量问题可能导致停机、数据损坏、硬件故障以及维护成本增加，造成业主损失。常见的电能质量症结有无功功率、谐波、三相不平衡。

长周期视角下美联储加息周期结束往往带来权益型 REITs 股息率与十债收益率利差走阔。美国权益型 REITs 股息率中枢从上市初期的 9.1%逐步降至约 3.7%左右，其中估值水平上升为直接原因。但权益型 REITs 股息率在大部分年份里仍跑赢十债收益率，两者近 30 年收益差额的均值中枢为 118BP；若剔除最新一轮加息潮两者利差的均值中枢约为 132BP。此外，美联储加息周期结束后或十债收益率出现大幅度下行时，往往会导致美国权益型 REITs 股息率与十债收益率利差在随后 6-8 个月内进一步走阔。

Healthcare equipment is used in dermatology, ophthalmology, cardiovascular studies, orthopedics, oncology, gynecology, dentistry, urology, and other therapy areas. The applications of these devices have expanded to all key diagnostics and therapeutics areas. Recently, most mid-sized and large hospitals are increasingly providing treatment along with imaging and diagnostic services. However, nowadays, most of these end-users increasingly prefer to leasing medical and healthcare equipment instead of buying new devices, as they are expensive and involve high installation and maintenance costs. The leasing of healthcare equipment makes it easy for end-users to change healthcare equipment and lease those with the latest technological advances.

Cloud computing has become a mainstream option today, offering a well-structured network for storing, sharing, and accessing information. This extensive network allows for quick and flexible access to services from a shared pool of resources, resulting in increased efficiency, reduced costs, and easier scalability. Many businesses have adopted cloud computing for improved customer relationship management (CRM). However, this approach enhances their ability to serve customers more effectively and bridges the gap between industries and end-users. Information is seamlessly shared, and services are increasingly personalized.
