“…The mechanical peel-off method for patterning S×S WOLEDs offers a nondestructive approach to high resolution, multiresist-level patterning of striped devices. The peel-off approach has previously been used to pattern organic photovoltaics on substrates as large as 25 cm 2 and can be scaled up to larger substrates using a roller to minimize stress on thin peel-off stripes . Such equipment can be readily incorporated into an N 2 environment, which is essential to prevent contamination during the device fabrication process …”

“…Current methods for S×S organic device patterning include vacuum deposition through fine metal shadow masks, direct patterning via organic vapor-jet printing, solution processing using ink-jet printing or microchannels, film transfer via laser-induced thermal imaging, and postdeposition processing via chemical lift-off. − A somewhat less complex and damage-free method that can achieve photolithographic resolution is mechanical peel-off, which has recently been demonstrated for patterning organic photovoltaics and perovskite light-emitting devices. , In this work, we demonstrate two-color, S×S WOLEDs deposited via vacuum thermal evaporation and subsequently patterned using mechanically peeled-off films. This method allows for multilayer patterning with micron-scale resolution while avoiding precise alignment of shadow masks, or exposing the individual color-emitting stripes to destructive solvents used in conventional photolithography.…”

White organic light-emitting diodes (WOLEDs) have become increasingly popular for use in solid-state illumination, where diffuse, large area light sources that achieve a high color rendering index and luminous power efficiency are desirable. Color-tunable emission, where the light source combines emission from multiple, separately addressed color elements, is conveniently provided by WOLEDs for the purpose of adapting the lighting source to a particular illumination requirement. In this work, we demonstrate a method for side-by-side positioning of monochromatic blue and yellow phosphorescent OLED stripes that are combined to create tunable white light, using a highresolution mechanical peel-off patterning method. We achieve a peak luminous power efficiency of 17.1 ± 0.3 lm W −1 and an external quantum efficiency of 11.8 ± 0.2% and demonstrate color tunability of the 1960 Commission Internationale d'Eclairage chromaticity coordinates from (u,v) = (0.33,0.36) to (0.12,0.32). This corresponds to a tuning range of the color rendering index from 74 ± 1 to 86 ± 1 and the correlated color temperature from 2000 to 8000 ± 500 K. Due to the nondestructive nature of the peel-off technique, patterned devices exhibit a lifetime comparable to conventional, shadow mask-patterned devices.

“…To meet these requirements of BIPVW, semitransparent organic photovoltaics (STOPVs) that are characterized by powerful charge generation, semitransparency, desired reflective or transmitted colors, flexible to allow perfect merging with the building, beyond the classic features of OPVs, become an optimal choice for BIPVW. [7][8][9][10][11][12][13][14][15] Of these, power generation, average visible transmittance, and architectural beauty become the first three important metrics for colored-BIPVW and gain extensive attention.…”

Multifunction‐integrated semitransparent organic photovoltaic cells (STOPVs), with high power generation, colorful transmittance/reflectance, excellent ultraviolet (UV) protection, and thermal insulation, are fully in line with the concept of architectural aesthetics and photoprotection characteristics for building‐integrated photovoltaic‐window. For the indelible rainbow color photovoltaic window, one crucial issue is to realize the integration of these photons‐ and photoelectric‐related multifunction. Herein, dynamic transmissive and reflective structural color controllable filters, with asymmetrical metal‐insulator‐metal (MIM) configurations (20 nm‐Ag‐HATCN‐30 nm‐Ag) through machine learning, are deliberately designed for colorful STOPV devices. This endows the resultant integrated devices with ≈5% enhanced power conversion efficiency (PCE) than the bare‐STOPVs, gifted UV (300–400 nm) blocking rates as high as 93.5, 94.1, 90.2, and 94.5%, as well as a superior infrared radiation (IR) (700‐1400 nm) rejection approaching 100% for transparent purple‐, blue‐, green‐ and red‐STOPV cells, respectively. Most importantly, benefiting from the photonic recycling effect beyond microcavity resonance wavelength, a reported quantum utilization efficiency (QUE) as high as 80%, is first presented for the transparent‐green‐STOPVs with an ultra‐narrow bandgap of 1.2 eV. These asymmetrical Febry‐Pérot transmissive and reflective structural color filters can also be extended to silicon‐ and perovskite‐based optoelectric devices and make it possible to integrate additional target optical functions for multi‐purpose optoelectric devices.

Solution Processed Semi‐Transparent Organic Solar Cells Over 50% Visible Transmittance Enabled by Silver Nanowire Electrode with Sandwich Structure

et al. 2023

Photovoltaic windows with easy installation for the power supply of household appliances have long been a desire of energy researchers. However, due to the lack of top electrodes that offer both high transparency and low sheet resistance, the development of high transparency photovoltaic windows for indoor lighting scenarios has lagged significantly behind photovoltaic windows where privacy issues are involved. Addressing this issue, in this work we develop a solution processable transparent top electrode using sandwich structure silver nanowires, realizing high transparency in semi‐transparent organic solar cells. The wettability and conducting properties of the electrode are improved by a modified hole‐transport layer named HP. The semi‐transparent solar cell exhibits good see‐through properties at a high average visible transmittance of 50.8%, with power conversion efficiency of 7.34%, and light utilization efficiency of 3.73%, which is the highest without optical modulations. Moreover, flexible devices based on the above‐mentioned architecture also show excellent mechanical tolerance compared with Ag electrode counterparts, which retains 94.5% of their original efficiency after 1500 bending cycles. This work provides a valuable approach for fabricating solution processed high transparency organic solar cells, which is essential in future applications in building integrated photovoltaics.This article is protected by copyright.
