利用具有（WO 3/LiF）N结构的一维光子晶体（1DPC）同时提高低禁带半透明聚合物太阳能电池（PSC）的效率和透过率。在580-780 nm的光子带隙（PBG）内，具有8对WO 3/LiF的1DPC充当分布反射器（DBR），其将580-780 nm的光波长反射回PSC中以供有源层重吸收。功率转换效率（PCE）为2.46%，与没有1DPC的器件相比，PCE提高了28.1%。在380-580 nm的光子通带内，1DPC充当反射涂层。在波长范围内保持40%的平均透射率，并且当与没有1DPC的器件相比时，该值提高了33%。最后，证明了器件的效率和透过率与重复周期数（N）有关。
One-dimensional photonic crystals (1DPCs) with the structure of (WO3/LiF)Nare employed to simultaneously improve the efficiency and transmittance of low bandgap semitransparent polymer solar cells(PSCs). Within the photonic bandgap(PBG) of 580–780 nm, 1DPCs with 8 pairs of WO3/LiF act as distributed reflectors (DBR), which reflects light wavelength of 580–780 nm back into the PSCs for reabsorption by active layers. Power conversion efficiency (PCE) of 2.46% is obtained for the semitransparent PSCs and there is an improvement of 28.1% in the PCE when compared with that of the device without 1DPCs. Within the photonic passband of 380–580 nm, the 1DPCs act as antireflection coatings. An average transmittance of 40% is remained within the wavelength range and the value is improved by 33% when compared with that of the device without the 1DPCs. Finally, it is demonstrated that the efficiency and transmittance of the device are dependent on the number of the repeated period (N).
