To do this, solar researchers have had to make complicated blends of materials to split the electrons apart to generate electricity. This has added significant complications and has resulted in efficiency losses.<\/p>\n<p>But in a paper published in <i>Nature Communications<\/i> today, researchers at Te Herenga Waka Victoria University of Wellington and the MacDiarmid Institute for Advanced Materials and Nanotechnology, leading a collaboration with the University of New South Wales and Peking University, have shown that in the one of the newest organic solar materials (named Y6) the electrons are im<a href=\"https:\/\/buradabiliyorum.com\/en\/category\/social-mediaa\/\" data-internallinksmanager029f6b8e52c=\"1\" title=\"Social Media\" target=\"_blank\" rel=\"noopener\">media<\/a>tely freed after being excited by light. This will improve power efficiency and allow researchers to move to simpler designs\u2014closer to traditional silicon solar panels.<\/p>\n<p>To prove that the electrons in the material Y6 were in fact behaving completely differently than expected, researchers led by Dr. Mike Price, Dr. Paul Hume and Prof Justin Hodgkiss conducted a comprehensive <a href=\"https:\/\/buradabiliyorum.com\/en\/category\/watch-movies-tv-seriess\/\" data-internallinksmanager029f6b8e52c=\"8\" title=\"Watch Movies &amp; TV Series\" target=\"_blank\" rel=\"noopener\">series<\/a> of laser spectroscopy measurements and theoretical calculations.
