Hello, I'm Materialscientist. I noticed that you made a change to an article, Polymer solar cell, but you didn't provide a reliable source. It's been removed for now, but if you'd like to include a citation and re-add it, please do so! If you need guidance on referencing, please see the referencing for beginners tutorial, or if you think I made a mistake, you can leave me a message on my talk page. Thank you.

Hello, I'm Materialscientist. I wanted to let you know that I undid one or more of your recent contributions to Polymer solar cell because it appeared to be promotional. Advertising and using Wikipedia as a "soapbox" are against Wikipedia policy and not permitted. Take a look at the welcome page to learn more about Wikipedia. Thank you.

[edit] Hello, I'm Materialscientist. I wanted to let you know that I removed one or more external links you added, because they seemed to be inappropriate for an encyclopedia. If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page, or take a look at our guidelines about links. Thank you.
