I've decided to leave my earlier CIGS posts in my personal blog for the simple reason that it seems complicated to move them here. Instead I'll provide the CIGS link to them with a little summary of the content here from oldest to newest.
A solar module: I-V curve of Ångström 12.5 x 12.5 cm module.
Solar cells, modules and panels: Series and parallel connections of CIGS devices.
A CIGS solar cell: Description of the layers that make up a CIGS cell.
My solar installation: My frustrations with Swedish laws making private ownership of solar panels uneconomical.
Building a solar charger: Building chargers using our own 12.5 x 12.5 cm square modules.
Nanosolar: Written in July, 2008 about why the hype around Nanosolar was just that - hype.
A CIGS day: Making CIGS with half the usual thickness.
The making of a CIGS solar cell: How I deposit the layers of a CIGS solar cell.
Patent application: As the title says.
Fun with setbacks: The copper evaporation source is broken.
Hello World: The first new co-contributor, Per-Oskar, introduces himself.
How does a CIGS solar cell respond to sunlight?: CIGS spectral response and the solar spectrum.
Hopefully, there will be more contributors. It would be great to have a site for sharing ideas and getting feedback. If you would like be a contributor, please leave a comment to this post.

To bad for us swedish citizens to loose you. I hope you liked it here, and that you return some day.
ReplyDeleteI live near Örebro and are wondering if there is a way to make copper solarcells in a lot less complicated way? If efficiency is'nt an isue. I mean a cell with around 5% efficiency should do the trick, if a could make it at home.
Hi Marta, your CIGS blog rocks! How did your CGS/CIS experiments go?

Sorry for not seeing these posts sooner - I had forgotten the "notification" setting and have also been busy changing country and job...
ReplyDeleteTo Kalle o pinglan: Tack, jag saknar Uppsala redan och tänker komma på bsök då och då. But, sorry, I don't have any hints on copper-based cells, even poor ones. If you want to make solar cells in your kitchen, then I suggest looking at dye sensitized solar cells (Grätzel cells). I don't have a link off-hand...
To buchacho: Thanks for the compliment. My CGS attempt got me 4%. Guess I needed a few more tries. Equipment failure (copper source) prevented me from continuing.
