Cyclen molecule manipulation for efficient and stable perovskite solar cells Although perovskite solar cells (PSCs) have been developed rapidly, the poor quality of perovskite films and difficulty in scalable fabrication in air condition hindered the improvement of PSC performance. In this work, a novel ring molecule, 1,4,7,10-tetraazacyclododecane (cyclen), is introduced to manipulate the high-quality film fabrication.

A 35-year-old man presented with bilateral large colloid drusen. Ultrawide-field fundus photography revealed several large colloid drusen in the macula and periphery of the retina (). Late-phase fluorescein angiography revealed hyperfluorescent drusen of varying size (). OCT revealed multiple dome-shaped retinal pigment epithelial elevations with variable internal reflectivity (). The upper OCT was acquired 6 years ago, whereas the lower OCT was acquired at a recent visit.
