碩士 === 國立虎尾科技大學 === 光電與材料科技研究所 === 98 === The derivative of C60, [6,6]-phenyl C61-butyric acid methyl ester( (PCBM), and 3-hexylthiophene (P3HT) were dissolved in o-Dichlorobenzene (DCB) solvent 24 hours, then spin-coated in Glass/ITO/PEDOT:PSS as active layer for polymer solar cells. The experimental parameters were studied carefully to obtain the optimum power conversion efficiency (PCE). The PEDOT: PSS be heated to 100℃ after spin-coating, the efficiency increase from 1.82% to 2.49%. When the slow dry in the use of a different DCB and nitrogen turnover has reached the optimum arrangement of PCBM and P3HT autonomy, the efficiency from 1.45% to 2.49%. Between the PEDOT: PSS and the active layer by adding a layer of P3HT film,as to enhance the absorption, efficiency increase from 2.49% to 2.69%. The glass surface add different light by light trapping structure arrived improve the scattered light that increase light path in active layer, and improve absorption and reduce the reflectance, efficiency increase from 2.69% to 3.02%. Finally try to manufacture (AgIn) xZn1-2xS phosphor to light the characteristics of excitation light allows solar electricity can also be absorbed into the powder through the AgInZnS fluorescent UV light.
