Abstract In this paper, we report a high-performance P3HT/PCBM bulk-heterojunction solar cell with a power conversion efficiency of 4.85% fabricated by adjusting polymer crystallinity and nanoscale phase separation using an ultrasonic irradiation mixing approach of the polymer. The results of grazing incidence X-ray diffraction, UV/Vis spectroscopic, and atomic force microscopic measurements of the P3HT/PCBM blend films reveal that the P3HT/PCBM film fabricated by ultrasonic irradiation mixing P3HT and PCBM solutions for 10 min has higher degree of crystallinity, higher absorption efficiency, and better phase separation, which altogether account for the higher charge transport properties and photovoltaic cell performance.

Online attention
Altmetric calculates a score based on the online attention an article receives. Each coloured thread in the circle represents a different type of online attention. The number in the centre is the Altmetric score. Social media and mainstream news media are the main sources that calculate the score. Reference managers such as Mendeley are also tracked but do not contribute to the score. Older articles often score higher because they have had more time to get noticed. To account for this, Altmetric has included the context data for other articles of a similar age.
