我国科研团队解锁太阳能电池“长寿密码”

华东理工大学的研究团队在《科学》杂志上发表成果,成功解决了钙钛矿太阳能电池稳定性差的问题。通过使用石墨烯和特殊透明塑料制成的超薄保护层,团队将材料的膨胀幅度从0.31%降低到0.08%,抗压能力翻倍,显著提高了电池的使用寿命。这种保护层使太阳能电池在强光高温环境下持续工作3670小时后,仍能保持97%的发电效率,是目前同类电池中最长的稳定工作时间。这项技术突破不仅提供了解决方案,还颠覆了科学界的认知,为后续研究打开了新方向。钙钛矿电池的生产成本仅为硅电池的1/3,且发电效率有提升空间,有望实现建筑外墙发电玻璃、可折叠户外充电毯等革命性变化,为全球绿色能源转型提供“中国方案”。

Should You Buy Bitcoin?

In general, many financial experts support their clients’ desire to buy cryptocurrency, but they don’t recommend it unless clients express interest. “The biggest concern for us is if someone wants to invest in crypto and the investment they choose doesn’t do well, and then all of a sudden they can’t send their kids to college,” says Ian Harvey, a certified financial planner (CFP) in New York City. “Then it wasn’t worth the risk.” The speculative nature of cryptocurrency leads some planners to recommend it for clients’ “side” investments. “Some call it a Vegas account,” says Scott Hammel, a CFP in Dallas. “Let’s keep this away from our real long-term perspective, make sure it doesn’t become too large a portion of your portfolio.” In a very real sense, Bitcoin is like a single stock, and advisors wouldn’t recommend putting a sizable part of your portfolio into any one company. At most, planners suggest putting no more than 1% to 10% into Bitcoin if you’re passionate about it. “If it was one stock, you would never allocate any significant portion of your portfolio to it,” Hammel says.

Telegram has exploded as a hub for cybercriminals looking to buy, sell and share stolen data and hacking tools, new research shows, as the messaging app emerges as an alternative to the dark web.An investigation by cyber intelligence group Cyberint, together with the Financial Times, found a ballooning network of hackers sharing data leaks on the popular messaging platform, sometimes in channels with tens of thousands of subscribers, lured by its ease of use and light-touch moderation.Readhub from us
