“…FAs have good characteristics, i.e., high electron mobility at room temperature such as 0.1 cm 2 /Vs [13,14]; however, their stability is low and has high synthetic cost [2]. The main advantages of NFAs as compared to FAs are their low voltage losses, low production cost and high efficiency [2].…”

“…In [ 34 ], the PTB7:PC 70 BM blend has been explored with different electron transport layer (ETL) materials, and it was found that Zn(O,S) is the most suitable partner, that achieved a PCE of 17.15%. Some simulation studies inspected the replacement of the conventional PEDOT:PSS with other promising candidates [ 35 , 36 , 37 ]. Regarding these simulation studies, and many others, all-polymer SCs based on polymerized acceptors have not been investigated by simulation until now, to the best of our knowledge.…”

Device Modeling of Efficient PBDB-T:PZT-Based All-Polymer Solar Cell: Role of Band Alignment

In this study, we present some design suggestions for all-polymer solar cells by utilizing device simulation. The polymer solar cell under investigation is formed by a photoactive film of a blend comprising PBDB-T as a polymer donor and PZT as a polymerized small molecule acceptor. The initial cell is based on a fabricated cell whose structure is ITO/PEDOT:PSS/PBDB-T:PZT/PFN-Br/Ag, which has a power conversion efficiency (PCE) of about 14.9%. A calibration procedure is then performed by comparing the simulation results with experimental data to confirm the simulation models, and the material parameters, implemented in the SCAPS (Solar Cell Capacitance Simulator) simulator. To boost the open circuit voltage, we investigate a group of hole transport layer (HTL) materials. An HTL of CuI or P3HT, that may replace the PEDOT:PSS, results in a PCE of higher than 20%. However, this enhanced efficiency results in a minor S-shape curve in the current density-voltage (J-V) characteristic. So, to suppress the possibility of the appearance of an S-curve, we propose a double HTL structure, for which the simulation shows a higher PCE with a suppressed kink phenomenon due to the proper band alignment. Moreover, the designed cell is investigated when subjected to a low light intensity, and the cell shows a good performance, signifying the cell’s suitability for indoor applications. The results of this simulation study can add to the potential development of highly efficient all-polymer solar cells.

“…Zn(O,S) was discovered to be a matching conjugate, obtaining a PCE of 17.15%, as reported in [ 35 ], in which a PTB7/PC 70 BM blend with various electron transfer layer (ETL) materials was tested. Different simulation studies have looked at substituting PEDOT:PSS with other alternatives [ 36 , 37 , 38 ]. Up to our knowledge, there are no existing simulation studies, including the mentioned studies and others, have explored all-polymer solar devices utilizing polymerized acceptors.…”

Based on experimental results, this theoretical study presents a new approach for investigating polymers’ solar cells. P-type PZT:C1 and N-type PBDB:T were used to construct a blend for use as a photoactive layer for the proposed all-polymer solar cell. Initially, an architecture of an ITO/PEDOT:PSS/PBDB:T/PZT:C1/PFN-Br/Ag all-polymer solar device calibrated with experimental results achieved a PCE of 14.91%. A novel inverted architecture of the same solar device, proposed for the first time in this paper, achieved a superior PCE of 19.92%. Furthermore, the optimization of the doping of the transport layers is proposed in this paper. Moreover, the defect density and the thickness of the polymer are studied, and a PCE of 22.67% was achieved by the optimized cell, which is one of the highest PCEs of polymer solar devices. Finally, the optimized polymer solar cell showed good stability amidst temperature variations. This theoretical study sheds light on the inverted structure of all-polymer solar devices.
