We have designed the semitransparent solar cells with two fullerene materials as active layers. we have used the two-dimensional(2D) photonic crystals (PC) in the active layer and investigated the optical parameters of these structures. We have utilized the Finite-difference time-domain (FDTD) method for our simulation and have shown that the effect of 2D photonic crystals in transmission, absorption, short-circuit current density (Jsc), and generation rate. We also found that the polymer donor poly[2,60-4,8-di(5-ethylhexylthienyl)benzo[1,2-b;3,3-b [dithiophene]-alt-[3-fluoro-2[(2-ethylhexyl)carbonyl]thieno[3,4-b[thiophenediyl] (PTB7- Th) with the visible absorbing fullerene acceptor [6,6]-phenyl-C71-butyric acid methyl ester (PC71BM), PTB7-Th:PC71BM, can be a better choice as an active layer compared with the poly(3-hexylthiophene) (P3HT) and [6,6]-phenyl C61-butyric acid methylester (PCBM), P3HT:PCBM. This study can be useful for light management in semitransparent organic solar cells.
