“…Based on the work of adhesion and the Young-Dupree equations, lowest surface tension of a solution leads to increased adhesion on top of a surface with given surface energy [37]. In addition, a decreased contact angle of PEDOT:PSS solution was found to lead in increased chemical interaction on the hydrophobic P3HT:PCBM film during processing, suggesting increased chemical interaction between the two organic layers and thus increased adhesion [38]. In general, P3HT:PCBM-PEDOT:PSS interface has been identified as the weakest interface in inverted OPVs.…”

“…In order to complete the solar cell, printing of an Ag grid was necessary on top of the PEDOT:PSS (layer 1 to 7 in Table 2 ) which defi ned an active area of 1 cm 2 . Considering that the interface P3HT:PCBM / PEDOT:PSS was well known to be the weakest in the device, [ 13 ] the presence of the top silver grid did not infl uence such interfacial adhesion (which was additionally confi rmed by preliminary tests) and thus full devices with Ag grid were neglected in the study. The PCE of the corresponding full fresh devices varied between 1.2% and 1.8%.…”

The role of the common stress factors such as high temperature, humidity, and UV irradiation on interface adhesion of roll‐to‐roll fabricated organic photovoltaic (OPV) devices is investigated. The samples range from bare front electrodes to complete devices. It is shown that applying single stress or combinations of stresses onto the samples variably affect the adhesion properties of the different interfaces in the OPV device. It is revealed that while the exposure of the complete devices to the stresses results in the loss of photovoltaic performance, some interfaces in the devices present improved adhesion properties. Depth profiling analysis on the fractured samples reveals interdiffusion of layers in the structure, which results in the increase of adhesion and change of the debond path. It is shown that through diffusion and intermixing of internal interfaces coupled stresses can increase the adhesion of OPV interfaces by over tenfold. The results are additionally compared to the photovoltaic performance of the complete devices.

“…2,27,33,[43][44][45] Prior measurements of adhesion energies are presented Table II and Figure 8. These show that the computed energy release rates (Figure 8) can exceed the measured adhesion energies (Figure 7) obtained in the interfaces that are present in OLED structures.…”

This paper presents the results of an analytical and computational study of the contacts and interfacial fracture associated with the cold welding of Organic Light Emitting diodes (OLEDs). The effects of impurities (within the possible interfaces) are explored for contacts and interfacial fracture between layers that are relevant to model OLEDs. The models are used to study the effects of adhesion, pressure, thin film layer thickness and dust particle modulus (between the contacting surfaces) on contact profiles around impurities between cold-welded thin films. The lift-off stage of thin films (during cold welding) is then modeled as an interfacial fracture process. A combination of adhesion and interfacial fracture theories is used to provide new insights for the design of improved contact and interfacial separation during cold welding. The implications of the results are discussed for the design and fabrication of cold welded OLED structures.
