I'm always personally interested in new solar applications – even though I realize they are often closely guarded. Nonetheless, if you have pictures, images, even drawings scribbled on the back of a napkin, submit it as a topic for the Solar Materials Science blog. I'm not picky at all, but I do love to see new tabbing, metallization paste printing, or sputtering applications.
Oh, another thing that would be great is sending in pictures of any defects you are seeing. If it is solder related we can help you solve the problem and help other readers at the same time. You can send them in anonymously too, that's fine.
