We demonstrate O2 plasma treated graphene oxides with a work function of 5.2 eV as high performance hole transport layer in organic solar cells. The transparency and simultaneously increase short circuit current, threshold voltage fill factor, resulting 30% cell efficiency.
High efficiency and stable polymer solar cells (PSCs) are fabricated by using solution-processed Zn1-xMgxO (ZMO) films as a novel class of cathode buffer layers (CBLs). They have the advantages tunable bandgaps energy levels, high optical transparency, good electron-transporting abilities. PSCs with an optimized ZMO CBL exhibit power conversion 8.31%, which is much better than those control devices without or ZnO CBL.

Most of the peak-to-average power ration (PAPR) reduction techniques, such as partial transmit sequence (PTS) algorithm and selective mapping algorithm, for conventional OFDM systems are not directly applied to filter bank multi-carrier with offset quadrature amplitude modulation (FBMC-OQAM) because overlapping structure FBMC-OQAM signals. Furthermore, complexity existing algorithms based on PTS is very high systems. In this letter, we propose a low-complexity hybrid processing (H-PTS)...
Filter-bank multicarrier with offset quadrature amplitude modulation (FBMC-OQAM) has been considered as an alternative scheme to orthogonal frequency division multiplexing (OFDM). However, the traditional channel estimation techniques of OFDM cannot be directly applied FBMC-OQAM system because real-field orthogonality signals. Although techniques, such least square (LS) and minimum mean error (MMSE), are widely via canceling intrinsic imaginary interference from adjacent data symbols, LS...
