Abstract In the present work, the stopping powers of alpha particle energies from near threshold energy to 10 MeV for light elements (37Li, 511B, 613C, 818O, 919F, 1022Ne, 1123Na, 1430Si) and medium elements (2145Sc, 2452Cr, 2657Fe, 2862Ni) have been calculated using the Zeigler formula. The cross-sections of the nuclear reactions 37Li(a,n)510B, 511B(a,n)714N, 613C(a,n)816O, […]

Abstract This study focuses on the architecture modification of solution-processed methylammonium lead iodide ((CH3NH3)PbI3)-based planar perovskite solar cells. The modification is obtained through a facile and cheap step formation at low temperature (<100 °C) using a simple inexpensive spin-coating technique. (CH3NH3)PbI3, as a light harvesting layer, was sandwiched between zinc oxide nanoparticle (ZnO-NP) thin film […]
