Rapid research and development in organic photovoltaics (OPVs) and light-emitting diodes (OLEDs) leads to optimize the efficiency further. Device efficiency and stability largely depend on components and the device structure of the solar cell. The aim of this report is to review the different strategies employed polymer as an electron transport material (ETM), hole transporting material (HTM) or as a templating agent to enhance the performance, stability, and durability of the perovskite solar cell. Keywords: Perovskite; Polymers; Solar cells; Efficiency Modern technology has a growing interest in the application of polymer as a flexible substrate in Dye-sensitized solar cells (DSSC), film-forming agents of the working electrode, platinum-free counter electrodes, and semi solid-state electrolyte. Uses of polymer in perovskite material lead to crystallization processes and work as an additive to adjust the nucleation. These polymers are generally used as an electron transfer material, hole transfer material or interface layer and work like to reduce the recombination rate and improves the separation efficiency of the charge carriers . Polymers are often used as buffer layers or donor layers in inorganic solar cells. Some polymer nanostructured are used to enhance device performance ,. Some low bandgap polymer materials are used as a hole transporting material in perovskite solar cells (PSC) to optimize efficiency as well as prevent cell degradation. Researchers are using a polymer-perovskite composite material to fabricate hybrid structures that are widely used in perovskite-based light-emitting diode (LED). Polymers encapsulated perovskite solar cell has a comparative longer lifetime and less degradation of materials than without encapsulation . The light absorption of Perovskite layer is less impacted by the polymer coating. Though polymers have a lot of advantages for uses in perovskite solar cell some issues like thermal stability in high temperature, water permeability through polymer layer and adhesive property of thin layer is challenging and lot of research work is going on to address the challenges . Recent trends of polymers application in perovskite-based solar cells and its achievements are reviewed and discussed in this article. Moreover, the practical challenges of polymer layered perovskite solar cell and implementation techniques are addressed. Polyanilines (PANI) PANI has high conductivity and used as a hole transporting material. PANI nanoparticles have between 20-60nm of size and can be produced via polymerization . PANI increases the light absorption property of the perovskite layer by improving the surface of perovskite thin film introducing the nanoparticles into a thin film. Conductive hole transport material in OLED is layered with PANI. Polytriarylamines (PTAAs) An exceptional electron blocking capabilities and low ionization is the key importance for choosing PTAA as a hole transport material in perovskite and OLED research. Amorphous materials have low hole mobility and PTAA has high void space. The crystal structure of PTAA can be improved by introducing planar moieties to transform it into more crystalline HTM material . Hole mobility of the material can be enhanced by suitable doping with cobalt compounds. PTAA containing Hydrophobic alkyl chain has a higher tendency to show hysteresis rather than hydrophilic ones. Polyfluorenes (PFO) Polyfluorenes and polyfluorene doped products are used as hole-transporting materials due to efficient hole extraction in perovskite solar cells. Only PFO has low oxidation potential and low valence band compared to perovskite. Suitable doping and structure change is possible by introducing an electron-rich triarylamine monomer that improves the valence band of the perovskite . After structure modification, it works better than polyfluorenes and better than spiro-OMeTAD in terms of hole extraction ability. Carbazole Due to desired electrical and tunable optical properties conjugated polymer based on Carbazole are now being used in perovskite-based solar cells. As an ideal hole transport material Carbazole based polymers are suitable in perovskite solar cells . By copolymerization process with 3,4-ethylene di-oxythiophene (EDOT), the newly formed compound has more electron-donating ability. 2,7-Cbz-EDOT and 3,6-Cbz-EDOT are the most popular among carbazole based material which is used as a hole transport material in perovskite solar cells. Polymer-based on sulfur-selenium materials Recent research reveals that sulfur-selenium material-based polymer can be used in perovskite solar cells as a hole transport layer. Photoluminescence property and photoinduced absorption quality are ideal for transfer quality charges. Sulphur-selenium based polymeric material used in perovskite solar cell has achieved 10.21% efficiency . The conductivity of this material is relatively good than other many polymeric materials. By introducing selenium material in the polymeric sulfur, it reduces the optical bandgap of the polymer. Selenium doped sulfur polymer has an impact on photoluminescence property of thin-film perovskite. Low bandgap polymers are introduced in OPV as well as perovskite solar cells to improve the absorption of infrared or near-infrared region wavelengths of light . Generally, lower bandgap polymer has higher hole transfer mobility than other HTM. Different variables like processing time, temperature, additives used has a high impact on the bandgap of the polymers.

How to Enable Searching Inside Google Drive/Docs Using Spotlight?
How to Enable Searching Inside Google Drive/Docs Using Spotlight?
I do not believe that Spotlight is technically able to index the content inside the Google Drive files, at least not files that were created from within Google Drive's web interface. For example, if I go to drive.google.com and create a new file (e.g. a Document) and insert some content (text) in the document, that new file representing that document will show up in my Mac's directory (i.e. /Users/myname/Google Drive/filename.gdoc). However if I take that file and open it in a text editor, I can see that the only content in the file is a link to the online file and some other information. The actual content of the google document is not in the file that's on my computer. Since the content of the document is not in the file that's on my computer, there's nothing for Spotlight to index.I think this is really unfortunate. The idea that I could use Spotlight to search through all of the files that I created online is really great, but it appears that Google Drive is not downloading the content of the files, so there is nothing for Spotlight to index. As you noted Precipitate provided that functionality, but it does not work any more and it's no longer developed.One non-spotlight alternative is to use the app Alfred to search:Google Drive Search with Alfred AppAll this really is is a shortcut to open your google drive in a web browser and initiate a search- not really what you (or I) want.There is also an app called Found that is able to search Google Drive, but that company was purchased and the app is no longer being developed. I have not tried the most recent version (which is from 2013), and the reviews on macupdate.com are mixed about its current functionality, but it might be worth a try1. Xbox 360 spotlight on E3?I THINK MICROSOFT AND NINTENDO ARE GOING TO CRUSH SONY2. Applications Don't Show Up in SpotlightWhen I tried Anil's solution, I got:sudo launchctl unload -w /System/Library/LaunchDaemons/com.apple.metadata.mds.plist /System/Library/LaunchDaemons/com.apple.metadata.mds.plist: Operation not permitted while System Integrity Protection is engagedInstead, I followed these instructions, and it worked:3. Prevent spotlight from indexing folders with a certain nameIn case anyone missed fsb's comment in the question, as I did. Apple provides a privacy tab in the Spotlight settings.Goto "System Preferences" > "Spotlight" > "Privacy" > "" Add folders to the list. Note: This may not work immediately, I had to restart Spotlight to see the effects4. How to disable Developer and Web Searches in Spotlight?Although the Search Results do not have toggles to sort or suppress these results, it's trivial to add the folders to the Privacy Pane.Perhaps something like this might work to Suppress the Developer hits? I do not see an obvious way to suppress the Web Search yet, but thankfully it's placed last as a catch all - last resort. I will probably feedback / bug Apple if 10.7.1 does not address that with a preference.5. How would you deal with your significant other being in the spotlight and adored by a lot of fans?Be ur self and u will get that6.

Why is Fox News giving a spotlight to these goofy "Tea Party" protests?You might want to re-evaluate your sense of reality8. Why is Palin putting Willow in the spotlight, and why is she dragging this out?SHE WANTS SOME ATTENTION BADLY, SHE LOST THE SPOT LIGHT SINCE SHE LOST THE ELECTION. SHE SHOULD RETIRE TO A IGLOO9. can i paint over a lens of a led spotlight?It wo not be as bright, Lu. How about a piece of colored film over it instead?10. Does the Sun, in addition to emitting its own light, reflect light? If a bright light was shone on the Sun, would it appear to be brighter?Yes, the sun reflects some of the light that hits it. However, that's not going to make the sun look brighter because any light striking the sun from the outside would be much, much, MUCH dimmer than the light produced by the sun.To see a noticeable increase in the sun's apparent brightness, you'd have to haul in a star much bigger than our sun to shine on it. Shining a flashlight or spotlight at our sun has no noticeable effect because the Sun is putting out about 3.8x10^26 watts of light power. To over-power that, you'd need a 1,000,000,000,000,000,000,000,000,000 Watt light bulb. That's not exactly available at Home Depot. "Hi! I need a 1000 yottawatt lightbulb, please!""I'm sorry, sir, but we appear to be out of those. Try checking back next Tuesday."Does the Sun, in addition to emitting its own light, reflect light?
