Φωτοβολταϊκά: εύκαμπτο Φ/Β απόδοσης 18,7% κατασκεύασαν Ελβετοί

Ελβετοί ερευνητές ισχυρίζονται πως κατασκεύασαν ένα εύκαμπτο φωτοβολταϊκό απόδοσης 18,7%.
Τα πρωτοποριακά εύκαμπτα φωτοβολταϊκά CIGS, κατασκευασμένα από χαλκό, ίνδιο, γάλλιο και διοξείδιο του σεληνίου, υπόσχονται να συμπιέσουν το κόστος της «ηλιακής» ηλεκτροπαραγωγής, καθώς αφενός είναι φθηνότερα και αφετέρου πλησιάζουν πλέον σε αποδοτικότητα τα φωτοβολταϊκά πολυκρυσταλλικής σιλικόνης και τα άκαμπτα CIGS.
Την έρευνα διενήργησε ομάδα επιστημόνων των Ομοσπονδιακών Εργαστηρίων Επιστήμης Υλικών και Τεχνολογίας της Ελβετίας (Empa).
Η ίδια ομάδα είχε επιτύχει την κατασκευή ενός φωτοβολταϊκού απόδοσης 17,6% τον Ιούνιο του 2010.
Την εμπορική εκμετάλλευση του νέου φωτοβολταϊκού θα αναλάβει η εταιρεία Flisom.

Awesome blog! Is your theme custom made or did you download it from
somewhere? A theme like yours with a few simple tweeks would
really make my blog shine. Please let me know where you got your design.
With thanks

Hello there! I know this is kinda off topic however I'd figured I'd ask.
Would you be interested in exchanging links or maybe guest authoring
a blog post or vice-versa? My blog covers a lot of the same subjects as yours and I feel we could
greatly benefit from each other. If you are interested feel free to send me an email.

I look forward to hearing from you! Great blog by the way!

I'm kinda paranoid about losing everything I've worked
hard on. Any tips?

Its like you read my mind! You seem to know so
much about this, like you wrote the book in it or something.

I think that you could do with some pics to drive the
message home a bit, but other than that, this is magnificent blog.

A great read. I will definitely be back.

Hello would you mind sharing which blog platform you're using? I'm planning to start my own blog soon but I'm having a tough time deciding between BlogEngine/Wordpress/B2evolution and Drupal. The reason I ask is because your design seems different then most blogs and I'm looking for
something completely unique. P.S Sorry for getting off-topic but
I had to ask!
