The blackest black for more efficient solar cells
MIT scientists claim to have created a material 10 times more black than anything witnessed to date. It is said to be able to absorb more than 99.96% of incoming light and reflect 10 times less light than other superblack materials. The invention may be interesting for the development of black silicon PV technology and carbon nanotube-based solar cells.

SMA: We can’t be credible if we’re not sustainable
Credibility comes not just from offering products that generate clean electricity, but also from the way in which those products are manufactured, says SMA Solar Technology CEO Jürgen Reinert. Here, transparency and sustainability are key. That’s why one of the world’s largest PV inverter producers has partnered with pv magazine’s UP sustainability initiative. In the following Q&A, Reinert lays out what SMA is doing to step UP its green game.

Silicon and perovskites should stick together, say Korean scientists
Researchers from the Ulsan Institute of Science and Technology have demonstrated a new method of fabricating perovskite-on-silicon tandem devices, using a transparent conductive adhesive to combine the two cells. The scientists have developed devices with demonstrated efficiencies of 19.4%, and propose strategies to bring that above 24% using existing technology.
