-benzothiadiazole)])/PCBM (PCPDTBT/PCBM). The J–V curves of the device were acquired through a multiscale simulation scheme. Then performance indices were evaluated and related to the thickness, inner morphologies and the weight ratio of the active layers. Finally, using a simplexsearching algorithm and genetic
accurate optimization results are required for tandem polymer solar cells.
For the purpose of relieving computational load and optimizing tandem device structures with all the structure parameters considered, we employed two searching algorithms: simplexsearching [30] and GA [31]. In simplexsearching
