Abstract Reduced graphene oxides (rGO) are synthesized via reduction of GO with reducing agents as a hole‐extraction layer for high‐performance inverted planar heterojunction perovskite solar cells. The best efficiencies power conversion (PCE) these rGO cells exceed 16%, much greater than those made and poly(3,4‐ethenedioxythiophene):poly(styrenesulfonate) films. A flexible device shows PCE 13.8% maintains 70% its initial performance over 150 bending cycles. It is found that the period...
Electric-field-induced changes in absorption and photoluminescence (PL) spectra PL decay profile have been measured for two-dimensional hybrid organic–inorganic halide perovskite semiconductor, ((C4H9NH3)2Pbl4) (N1). Electroabsorption (E-A) observed at room temperature a low of 45 K were analyzed by assuming the Stark shift, magnitudes change electric dipole moment polarizability following photoexcitation determined. The strong signal E-A was interpreted terms weak band which shows extremely...
The dependence of photoluminescence (PL) on excitation power and the effect an external electric field have been studied for a two-dimensional (2D) perovskite (C4H9NH3)2PbI4 thin-film sample. efficiency dissociation hot excitons to produce free carriers was enhanced with small because relaxation cold emissive slow, indicating that thermal energies can be utilized in solar cells under weak photoirradiation. notably applied field, resulting efficient field-induced quenching PL. present results...
Self-assembled monolayers (SAMs) with short organic chains terminated specific functional groups are attractive for modifying surface properties a variety of applications, including being copper diffusion barrier layer on Si wafer. However, SAM formation is process-sensitive and ideal difficult to obtain, both which need carefully deal before practical use. Herein we developed system achieve seamless electroless deposited (ELD Cu) film an amino-terminated silane modified wafer the help...
