Abstract Perovskite solar cells (PSCs) have reached an impressive efficiency over 23%. One of its promising characteristics is the low-cost solution printability, especially for flexible cells. However, printing large area uniform electron transport layers on rough and soft plastic substrates without hysteresis still a great challenge. Herein, we demonstrate slot-die printed high quality tin oxide films PSCs. The inherent induced by layer suppressed using universal potassium interfacial...
Therapeutic nanoreactors have been proposed to treat cancers through in situ transformation of low-toxicity prodrugs into toxic therapeutics the body. However, vivo applications are limited by low tissue-specificity and different tissue distributions between sequentially injected prodrugs. Herein, we construct a block copolymer prodrug-based polymersome nanoreactor that can achieve novel orchestrated oxidation/chemotherapy cancer via specific activation at tumor sites.
