Minimizing buried interfacial defects for efficient inverted perovskite solar cells

Science, 2023
Controlling the perovskite morphology and defects at the buried perovskite-substrate interface is challenging for inverted perovskite solar cells. In this work, we report an amphiphilic molecular hole transporter, (2-(4-(bis(4-methoxyphenyl)amino)phenyl)-

Proceedings of the 8th International Conference on Predictive Models in Software Engineering, 2012
Defect prediction has been a very active research area in software engineering [6--8, 11, 13, 16, 19, 20].In 1971, Akiyama proposed one of the earliest defect prediction models using Lines of Code (LOC) [1]: "Defect = 4.86 + 0.018LOC."Since then, many effective new defect prediction models and metrics have been proposed.
