2月25日,中国科学院等研究团队在《自然·能源》(Nature Energy)上发表论文Regulating grain growth via Li2SnS3 interphase in kesterite solar cells with certified efficiencies exceeding 15%,报告了一种新型铜锌锡硫硒太阳能电池,可实现超过15%的光电转换效率。研究团队创新性提出Li₂SnS₃界面相调控策略,通过改性阳离子迁移路径,实现Zn²⁺与Sn⁴⁺的迁移平衡。该Li₂SnS₃界面相可选择性包覆Cu₂Sn (S,Se)₃中间相晶粒,成为离子迁移的速率控制层,将界面相中Zn²⁺/Sn⁴⁺的迁移势垒差从Cu₂Sn (S,Se)₃中的0.41eV降至0.21eV,有效促进了更大尺寸、更均匀的高结晶度晶粒的形成。由此,器件的光电转换效率从13.86%大幅提升至15.45%;同时,在1.10 eV带隙下,器件的开路电压突破至602 mV。

We have plenty of memory for both of these, but we do hit another inconvenience when we define the new characters; we’re using the Extended Color Mode for both the game board and the status window, and we cannot get 8 characters together for our new button graphic without overwriting some of the punctuation that we need in the status line. That’s not really a problem for us, though, because we can just turn off Extended Color Mode for the status line and get 256 characters back. In fact, as long as we’re doing that, we really might as well just switch back to the system font and get mixed-case text while we’re at it:,详情可参考电影
Some of these laws impose requirements on System76 and Linux distributions in general. The California law, and Colorado law modeled after it, were agreed in concert with major operating system providers. Should this method of age attestation become the standard, apps and websites will not assume liability when a signal is not provided and assume the lowest age bracket. Any Linux distribution that does not provide an age bracket signal will result in a nerfed internet for their users.
