The work of chemistry professor <a href=\"http:\/\/www.nd.edu\/~pkamat\/index.html\">Prashant Kamat<\/a> and colleagues is described in the 6 December issue of the journal <a href=\"http:\/\/pubs.acs.org\/doi\/abs\/10.1021\/nn204381g?journalCode=ancac3\"><em>ACS Nano<\/em><\/a> (paid subscription required).<\/p>\n<p>Kamat&#8217;s team based the compound on nanoscale semiconductor particles (one nanometer equals one billionth of a meter) called quantum dots, made from titanium dioxide. The basic nanoparticles were then coated with either cadmium sulfide or cadmium selenide, and mixed in a water-alcohol suspension to create a paste.<\/p>\n<p>The team applied the paste to a conducting glass surface and submitted it to a heat treatment equivalent to 200 degrees C. When exposed to light, the painted surface generated electric power. However, the highest light-to-energy conversion achieved was about 1 percent, well below the 10 to 15 percent efficiency of conventional solar cells.<\/p>\n<p>Kamat and colleagues plan to further develop the solar paint, named Sun-Believable, not only to increase its conversion efficiency but also to improve the stability of the new material. &#8220;[T]his paint can be made cheaply and in large quantities,&#8221; says Kamat. &#8220;If we can improve the efficiency somewhat, we may be able to make a real difference in meeting energy needs in the future.&#8221;<\/p>\n<p>Read more: <a href=\"http:\/\/sciencebusiness.technewslit.com\/?p=5102\" rel=\"prev\">Solar Panels Resembling Ivy to be Installed at University<\/a><\/p>\n<p style=\"text-align: center;\">*\u00a0\u00a0\u00a0\u00a0 *\u00a0\u00a0\u00a0\u00a0 *<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Researchers at University of Notre Dame in Indiana have created an inexpensive paste made with semiconducting nanoparticles to produce a spreadable substance that can generate energy.
