New architecture in dye sensitized solar cells: a SCAPS-1D simulation study

摘要

In this paper, we present the performance of two solid-state dye sensitized solar cells (ssDSSCs) through SCAPS-1D simulation. The five layers of proposed structures are in solid-state. Recombination reactions and defects in materials were not considered to obtain maximum efficiency. The conjugated polymer BEHP-co-MEH PPV (poly{[2-[2′,5′-bis(2″-ethylhexyloxy)phenyl]-1,4phenylenevin-ylene]-co-[2-methoxy-5-(2′-ethylhexyloxy)-1,4-phenylenevin-ylene]}) and MoO_2/MoO_3 are studied by first time in a ssDSSCs using SCAPS-1D program. The current-voltage characteristic (I-V or J-V) and Quantum Efficiency behavior is analyzed and compared. The efficiencies achieved with BEHP-co-MEH PPV/MoO_2MoO_3 and BEHP-co-MEH PPV/PEDOT:PSS are 8.42% and 7.95%, respectively. A solar cell with these characteristics can be included in a manufacturing workflow allowing its large-scale production.
