Recent portable electronic devices have strict requirements regarding size, weight, and power. The power needed directly impacts the size of the required batteries, and larger batteries compromise the sizes and weights of portable devices. In order to design successful portable devices that maximize power and minimize size, devices should be operated in lowpower-consuming or self-powered mode. ...
The CH3NH3PbI3 is one of the most widely used and famous lead halide perovskite absorber layer for using in perovskite solar cells. One of the ways to deal with the instability problem of this perovskite structure in environmental condition is bromide doping in this composition. In this work, the structural and optical properties of the bromide doped CH3NH3PbI3 absorber layers were studied as w...
A modified morphology was introduced for poly(3-hexylthiophene):phenyl-C71-butyric acid methyl ester (P3HT:PC71BM) bulk heterojunction (BHJ) solar cells by thermal and solvent annealing treatments in the presence of hydrophilic-hydrophobic block copolymers. Power conversion efficiency (PCE) plummet was prohibited during both thermal and solvent treatments for all BHJ devices modified wit...
