The properties of polyethylene can be divided into mechanical, chemical, electrical, optical, and thermal properties. Polyethylene is of low strength, hardness and rigidity, but has a high ductility and impact strength as well as low friction. It shows strong creep under persistent force, which can be reduced by addition of short fibers. It feels waxy when touched. WebIn this paper, are use Polyethylene Oxide (PEO) particles to control the morphology of Formamidinium (FA)-rich perovskite films and achieve large cereals with improved optoelectronic properties. Consequently, a planar perovskite solar cell (PSC) is fabricated at additions of 5 wt% of PEO, and to highest PCE of 18.03% been obtained. This solar single …
