| Summary: | 碩士 === 元智大學 === 光電工程研究所 === 97 === Due to photovoltaic conversion efficiency of the organic polymer solar cells is closely related the charge transport mobility. But it’s low carrier mobility in organic polymer. So, in this study would change the poly-disperity in MEH-PPV to improve the hole mobility. We used chlorobenzene to be the dissolving for MEH-PPV and drop-cast fabricate thick films. Measurement the MEH-PPV hole mobility and poly- dispersity by time of flight method, photoluminescence, hotoluminescence excitation, and GPC. Experimental results show, the holes mobility are improved for change the poly-dispersity MEH-PPV. And then, the photovoltaic conversion efficiency of the organic polymer solar cells will be raised.
