ABSTRACTWe demonstrate improved compatibility of poly(ethylene dioxythiophene):poly(styrene sulfonate) (PEDOT:PSS) hole transport layer with acid-sensitive materials by addition of a simple base, NaOH or NH4OH, to the aqueous suspension to increase pH. Addition of NaOH to the acidic PEDOT:PSS allowed the deposition of PEDOT:PSS on top of an inverted poly(3-hexylthiophene):ZnO nanoparticle blend hybrid photovoltaic device, and improved device performance due to preservation of the ZnO electron acceptor. To quantitatively investigate the impact of base addition to hole transport layer properties and device performance, we deposited PEDOT:PSS with different pH values on inverted poly(3-hexylthiophene):[6,6]-phenyl-C61-butyric acid methyl ester bulk heterojunction devices. We find that NaOH modification results in a substantial work function decrease and series resistance increase. In contrast, the volatile NH4OH leaves PEDOT:PSS with minimal changes in film properties and device performance.

The Impact

It is crucial to find a good material as a hole transport layer (HTL) to improve the performance of perovskite solar cells (PSCs), devices with an inverted structure. Polyethylene dioxythiophene-poly (styrene sulfonate) (PEDOT:PSS) and inorganic nickel oxide (NiOx) have become hotspots in the study of hole transport materials in PSCs on account of their excellent properties. In our research, NiOx and PEDOT: PSS, two kinds of hole transport materials, were prepared and compared to study the impact of the bottom layer on the light absorption and morphology of perovskite layer. By the way, some experimental parameters are simulated by wx Analysis of Microelectronic and Photonic Structures (wxAMPS). In addition, thin interfacial layers with deep capture levels and high capture cross sections were inserted to simulate the degradation of the interface between light absorption layer and PEDOT:PSS. This work realizes the combination of experiment and simulation. Exploring the mechanism of the influence of functional layer parameters plays a vital part in the performance of devices by establishing the system design. It can be found that the perovskite film growing on NiOx has a stronger light absorption capacity, which makes the best open-circuit voltage of 0.98 V, short-circuit current density of 24.55 mA/cm2, and power conversion efficiency of 20.01%.

In this study, we incorporated silver nanowires (AgNWs) into poly(3,4-ethylenedioxythiophene):poly(styrene sulfonate) (PEDOT:PSS) as a hole transport layer (HTL) for inverted perovskite solar cells (PVSCs). The effect of AgNW incorporation on the perovskite crystallization, charge transfer, and power conversion efficiency (PCE) of PVSCs were analyzed and discussed. Compared with neat PEDOT:PSS HTL, incorporation of few AgNWs into PEDOT:PSS can significantly enhance the PCE by 25%. However, the AgNW incorporation may result in performance overestimation due to the lateral charge transfer. The corrosion of AgNWs with a perovskite layer was discussed. Too much AgNW incorporation may lead to defects on the interface between the HTL and the perovskite layer. An extra PEDOT:PSS layer over the pristine PEDOT:PSS-AgNW layer can prevent AgNWs from corrosion by iodide ions.

We have investigated the effect of diluting treatment of poly (3,4-ethylenedioxythiophen e):poly (styrene sulfonate)(PEDOT:PSS) solution on the PEDOT:PSS films and the organic polymer solar cells based on poly [4,8-bis (5-(2-ethylhexyl) thiophen-2-yl) benzo [1,2-b;4,5-b0] dithiophene-co-3-fluorothieno [3,4-b] thiophene-2-carboxylate](PTB7-Th):[6,6]-phenyl-C61-butyric acid methyl ester (PC61BM) using PEDOT:PSS polymer as the hole transport layer. The diluted PEDOT:PSS solution by water with 1:1.5 volume ratio was used to fabricate the hole transport layer in the organic solar cell, the fill factor and the shunt resistance of the solar cell can be significantly enhanced compared with the control cell, up to 64% and 949.03Ω·cm2, respectively.

Exceptional progress in the performance of perovskite solar cells in a very short time has made it a potential photovoltaic technology for future deployment. The compositional engineering in perovskite materials and other buffer layers makes it a feasible candidate for commercial applications in the near future. However, there are certain challenges associated with these devices which need to be addressed such as device stability, process dependent device efficiency, hole transport layer (HTL) etc. The device performance is highly dependent on the processing parameters of the precursors. Understanding the origin of this challenge is very crucial for reproducible device performance. In this work, we have focused on utilizing NiO as a HTL in planar perovskite solar cells and studied the ageing effect of NiO precursor solution on the perovskite film quality in terms of crystallinity, grain growth, surface morphology, and overall device performance. It is observed that the ageing of NiO precursor promotes the formation of NiO films with increased roughness which improves the perovskite film quality. Structural and morphological studies revealed that the perovskite films formed on aged NiO films were highly crystalline in nature, uniform and with larger grain size. Current– voltage characteristics under illumination show that the films casted from NiO aged solution are better for perovskite solar cell applications and result in reduced parasitic resistances and enhanced charge transport.

Dmso Treatment

In this work, we investigated how the performance enhancement of an organic X-ray detector was improved by adding a dimethyl sulfoxide (DMSO) polar solvent to poly(3, 4-ethylene dioxythiophene):poly(4-styrene sulfonate) (PEDOT:PSS) hole-transport layer. The changes in the properties, such as surface roughness, chemical structure, sheet resistance, and absorbance, of the PEDOT:PSS film caused by the DMSO treatment were examined. The application of DMSO treatment lowered the resistance of the PEDOT:PSS film because of the removal of PSS and the chemical structure change after DMSO treatment, and thus the transport of light-induced carriers was increased. The organic detector treated with 10 vol% DMSO showed the highest collected current density (CCD) of 357.42 nA/cm2 and highest sensitivity of 2.58 mA/Gy ·cm2, which were 31.88% and 32.31% higher than the CCD and sensitivity of the detector without DMSO treatment.
