The effect on the J–V behavior of polymer solar cells (PSCs) based on the active layer PTB7:PC71BM under a previous application of an external electric field (Eext) is presented. The active layer is doped with 0.01–0.04 wt. ratio (with respect to

We introduce the use of facilely synthesizable and low-bandgap boron chromophores as donors in planar heterojunction solar cells. We show that simple changes in the compositional properties of these molecules can improve the performance of the device

OPVs cells based on the well known photoconductor polymer blends of P3HT:PC 61 BM were fabricated by using Wood's metal as cathode under a vacuum free process. Wood's metal is a eutectic alloy of Pb/Bi/Cd/Sn (25%, 50%, 12.5% and 12.5%, respectively)

In this work, we propose the use of Woods metal, which is an eutectic alloy of Pb/Bi/Cd/Sn (25%, 50%, 12.5% and 12.5%, respectively), as a convenient substitute to evaporated aluminum for testing polymeric organic photovoltaic (OPVs) devices. The Woo

A poly-crystalline YAG matrix was obtained through the precipitation method; this matrix was single and co-doped with ytterbium and erbium ions, i.e., Yb:YAG, Er:YAG and Yb,Er:YAG. It is found that the measured luminescent properties are similar to t
