Abstract

To achieve high efficiency for organic solar cells, tandem structures have been constructed. In this paper, we suggest a numerical study on the optimization of the thicknesses of organic tandem solar cells (OTSCs) based on common materials with high availability, poly(3-hexylthiophene) (P3HT) and polythieno[3,4-b]-thiophene-co-benzodithiophene (PTB7). Based on the results of optical simulations, the optimized design of an OTSC is made possible in terms of a broad spectral response and high efficiency. To achieve high efficiency and a short circuit current (J_SC), we suggest a rational design via thickness optimization of each subcell for OTSC. A combined thickness of 200 nm and 200 nm for each single OPV cell is proposed for OTSC to realize a current matching with 8.00 mA/cm² of J_SC. Accordingly, a maximum power conversion efficiency (PCE) is achieved up to 10.11%.
