Hasta La Gadget!

Sharp has announced an unusual photovoltaic panel for the Japanese market that collects energy from the sun while still allowing the light to shine on through. Though it’s rated at a lowly 6.8 percent / 98 watt max efficiency, the glass-like properties make it useful as a construction material (as shown in the balcony railing above), with the semi-transparent nature giving occupants privacy, to boot. The energy-producing cells are embedded in a laminated glass structure and an air slot provides a thermal barrier, allowing the panels to also be used as “windows, curtain wall and eaves” according to Sharp’s PR. Though the system won’t win any potency prizes, it has garnered a design award in Japan, so it won’t blight any landscapes. There’s no mention of pricing or western availability so far, but you can hit the source for all the technical details.

There have been more than a few solar power efficiency records set in the past few months, let alone years. What makes IBM, DelSolar, Solar Frontier and Tokyo Ohka Kogyo think they can just waltz in and claim a record of their own? By using more commonplace elements in the periodic table, that’s how. The partnership’s new photovoltaic cell based on copper, zinc and tin (CZTS for short) can convert light rays to electric power with a 11.1 percent efficiency rate — still nothing to upset traditional silicon power, but a large 10 percent more efficient than anything else in the class. In its early form, CZTS can already be manufactured through ink printing and could be produced in quantities equivalent to about 500 gigawatts of power per year, or five times more than some of the next-closest alternatives. The group wants to improve CZTS’ efficiency over the course of the next several years, ideally reaching the point where it’s useful as a truly cheap, ubiquitous source of power. We’re looking forward to the day when there’s a little slice of solar energy in just about everything, hopefully including a few more hybrid cars and private aircraft.

Alt-week peels back the covers on some of the more curious sci-tech stories from the last seven days.

This week we swing by some superhero news, look at how solar panels might shape up in the future, explore a Lego forest and see how to grab dark matter just using some household gold and strands of DNA. Not only that, we discover how the sun likes to celebrate the fourth of July with its own firework display. This is alt / week
