解决方案 顺序沉积伪平面异质结:最先进的有机太阳能电池的有效 …
体异质结 (BHJ) 结构已广泛用于高效 OSC 的活性层。 然而,由于结晶和相分离之间的竞争耦合,BHJ 形态的精确调控仍然具有挑战性。 近年来,一种通过固溶顺序沉积制备的新型伪平面异质结 (PPHJ) 结构引起了广泛关注。 它是一种易于制备的结构,其中相分离结构、界面和分子堆积可以单独控制。 采用 PPHJ 结构,OSC 的性能,如功率转换效率、稳定性、透明度、柔韧性等,通常优于 BHJ 同类产品。 因此,应考虑对 PPHJ 结构的成膜过程、形态控制和器件性能的全面 …
bhj球笼式等速万向联轴器 - menowa.cn
2023年6月5日 · 万向联轴器 利用其机构的特点,使两轴不在同一轴线,存在轴线夹角的情况下能实现所联接的两轴连续回转,并可靠地传递转矩和运动。 万向联轴器有较大的角向补偿能力,结构紧凑,传动效率高。 不同结构型式万向联轴器两轴线夹角不相同,一般在5°-45°之间。 万向轴 用来联接不同机构中的两根轴(主动轴和从动轴),使之共同旋转,以传递扭矩的机械零件。 在高速重载的动力传动中,有些联轴器还有缓冲、减振和提高轴系动态性能的作用。 联轴器由两半 …
