Those lucky enough to be enjoying the Texas sunshine at SXSW may also get to see a rather nice solar shirt catching some photons. While this is not the first solar shirt it for charging your energy hungry devices (see Tommy Hilfiger for example) Pauline van Dongen design looks both good and practical using technology from the Holst Centre and TNO in the Netherlands. Though it is hard to tell from photos the many small solar panels look flexible and are connected with conductive stretchable material, which should make the garment feel natural on the body; something that does not feel rigid.
For those that need the numbers there are 120 thin film OLED solar cells that combine to produce about 1 W of power. The cells can be ironed on as well as sewn.
