Embodiment 1

[0184] Example 1: Preparation of patterned silver nanowires disposed on a substrate

[0185] An aqueous coating solution obtained from Cambrios Technologies Corporation was prepared containing silver nanowires, hydroxypropylmethylcellulose (HPMC), Triton X-100, and water. Silver-coated glass substrates were prepared using clear Eagle 2000 glass supplied by Coresix Precision Glass Inc. The glass size is 152.4mm×152.4mm. The glass was pretreated with UV ozone for 10 minutes. The substrates were prepared using a Headway Research Inc. spin coater Model #PWM32-PS-CB15PL. Use a recessed chuck to obtain a uniform coating. On a spin coater rotating at 500 rpm, 10 ml of the coating solution was dispensed on the glass substrate for 60 seconds. The coating was then dried in a convection oven at 50°C for 2 minutes and baked on a hot plate at 180°C for 90-120 seconds. The sheet resistance of the coating was measured to be 15-17 ohms / sq (measured by a Delcom 717B conductivity monitor...

Embodiment 2

[0188] Example 2: Coating of silver nanowire substrates with PLEXCORE OC HIL A formulation

[0189] Coating a silver coating patterned as described in Example 1 with the HIL material prepared in Example 5 produced a non-uniform hazy film on top of the silver nanowire coating. Dilute the HIL with 3 parts by weight: 2 parts by weight methanol. The diluted formulation was spin-coated on the patterned film of Example 1 at 1000 rpm for 30 seconds. This was followed by a drying step at 50°C for 5 minutes and baking at 160°C for 25-30 minutes. This produced a coating of 70-80 nm as measured by a surface profilometry tool. The combined transmittance of the conductive coating and the HIL topcoat was measured to be 86% for the film only.

Embodiment 3

[0190] Embodiment 3: preparation active layer ink

[0191] PLEXCORE P3HT was prepared as described in US Patent Publication 2008 / 0319207. An ink was prepared from P3HT and a fullerene derivative by adding 542 mg of solid to 23.5 g of 1,2-dichlorobenzene. The ink was stirred at about 60°C for 2 hours and then allowed to cool.

Abstract

Organic electronic devices, compositions, and methods are disclosed that employ electrically conductive nanowires and conducting materials such as conjugated polymers such as sulfonated regioregular polythiophenes which provide high device performance such as good solar cell efficiency. Devices requiring transparent conductors that are resilient to physical stresses can be fabricated, with reduced corrosion problems.

Description

[0001] related application [0002] This application claims priority to US Provisional Application No. 61 / 246,913, filed September 29, 2009, which is hereby incorporated by reference in its entirety. Background technique [0003] Improved materials and material combinations are needed for organic electronic devices employing transparent conductors, such as organic light-emitting diodes (OLEDs), polymer light-emitting diodes (PLEDs), organic photovoltaics (OPVs), flat-panel liquid crystal displays, touch panels, etc. Transparent conductors based on conductive nanowires have been proposed to address the shortcomings of traditional metal oxide materials such as indium tin oxide (ITO). However, transparent conductors, including those based on nanowires, may not work well with other materials. Contents of the invention [0004] Embodiments described herein include, for example, liquid and solid compositions, devices, articles, methods of manufacture, and methods of using the com...
