The photovoltaic properties of solar cells were investigated via spin coating the poly (2-methoxy-5-(2′-ethyl-hexyloxy)-1,4-phenylene vinylene) (MEH-PPV) and a newly synthesized n-type difluoro [2-(2-pyridinyl)-1H-indene-1,3(2H)-dionato-N2, O1]-(T-4)-boron (PIDB) with lower LUMO level as active layers. The active layers were characterized in solid state by means of absorption and photoluminescence (PL) spectra with three mixtures ratios in weight. Compared to the pure MEH-PPV, the results showed the blend of MEH-PPV and PIDB enhanced the light intensity as well as broadened the wavelength range of absorption; the intensities of PL spectra of the blends are quenched and confirmed the electron transferred from the photoexcited MEH-PPV backbone to PIDB. Much higher power conversation efficiency was achieved when their mixtures were with a ration of 1:1 by weight. The improved performance of device is attributed to the reduction of contact resistance, which derived from the impedance analysis.
