TL;DR: Grazing-incidence x-ray diffraction and atomic force microscopy were performed on bulk heterojunction regioregular poly(3-hexylthiophene) (RR-P3HT) [6,6]-phenyl-C71-butyric acid methyl esters spin-cast films with different film processing conditions to correlate the crystalline nanostructure of P3HT with the corresponding solar cell performance.

TL;DR: Reduction of hysteresis by minimizing trap density via controlling thermal annealing time leads to the stabilized PCE of 18.84% from the normal planar structured FA0.9Cs0.1PbI3 PSK solar cell.

TL;DR: The amine-functionalized UCNPs show intense near-infrared upconversion luminescence and were successfully applied in the lymphatic capillary bioimaging of small animals with a high signal-to-noise ratio, suggesting that these surface- functionalizedUCNPs are promising candidates for luminescent biolabels.

TL;DR: A low-cost and stable conjugated donor polymer (PTQ10) was introduced as interfacial layer in the planar n-i-p structured pero-SCs and proved to be an effective hole extraction layer due to the proper energy alignment with perovskite.
