美国《Appl Phys Lett》1992年7月报道了日本电化学实验室关于有机半导体微观PN结光电性质的研究。科学家们在半透明的Al电极上淀积了5层廿(碳)烷酸(C_(20))LB膜,其作用是形成电极与有源层之间的阻挡接触。有源层是在C_(20)层上的10层交替异质MC和PQ LB膜,即5个分子P-N结单元。MC是P型染料,PQ是N型染料。6层C_(20)。的LB膜和半透明的Al电极是上电极,其作用与下电极相同。电极尺寸为0.4mm~2,总厚度为57nm(2.7nm×21层),在异质LB膜中,发色团位于亲水物的侧面,在亲水物界面处形成了微观P-N结。对应于分子疏水部
The United States “Appl Phys Lett” in July 1992 reported the Japan electrochemical laboratory on organic semiconductors PN junction photovoltaic properties of the study. The scientists deposited 5 layers of 20-carbon acid (C 20) LB films on translucent Al electrodes, which act to form a barrier contact between the electrodes and the active layer. The active layer is 10 layers of alternating heterogeneous MC and PQ LB films on the C_ (20) layer, ie, 5 molecules of P-N junction units. MC is a P-type dye and PQ is an N-type dye. 6th floor C_ (20). The LB film and the translucent Al electrode are the upper electrodes, which function the same as the lower electrodes. The electrode size is 0.4mm ~ 2, the total thickness is 57nm (2.7nm × 21). In the heterogeneous LB film, the chromophore is located on the side of the hydrophilic material, and the microscopic P-N junction is formed at the hydrophilic material interface. Corresponds to the molecular hydrophobic part
