油漆太阳能电池开发Paint-On Solar Cells Developed
科学日报（2011年12月21日） -试想一下，如果未来的涂料外衣，你把你家的外产生电力从光-电，可用于电源内的家电和设备.
圣母大学的研究人员队伍已朝着这一设想，通过建立一个廉价的“太阳能电池油漆”，使用半导体纳米粒子产生能量的一大进步。
Prashant KAMAT，Zahm科学教授约翰·A·在化学和生物化学，在巴黎圣母院的纳米科学与技术中心（NDnano）研究员说：“我们希望做一些变革，以摆脱目前的硅基太阳能技术，”谁领导的研究。
“通过整合电力生产纳米粒子，称为量子点，到涂抹的化合物，我们已经取得了一个大衣无需特殊设备，可用于任何表面导电的太阳能涂料。”
搜索队的新材料，ACS的纳米二氧化钛，涂要么硫化镉或硒化镉纳米粒子为中心，在该杂志描述。然后粒子悬浮在水醇的混合物，以创建糊状。
粘贴时被刷上透明导电材料，暴露在光线下，它创造了电力。
KAMAT“解释说：”最好我们迄今达成的光能量转换效率为1％，这是平时的10％至15％的商业硅太阳能电池效率远远落后。
“但这种涂料可以取得廉价和大批量。如果我们能效率有所提高，我们也许能够在满足能源需求在未来的真正的区别。”
“这就是为什么我们命名为新的油漆，孙可信，”他补充道。
KAMAT和他的团队还计划，研究如何提高新材料的稳定性。
NDnano是在世界上领先的纳米技术中心之一。其使命是研究生命系统和操作的材料和设备的性能，以及它们的接口，在纳米尺度。
ScienceDaily (Dec. 21, 2011) — Imagine if the next coat of paint you put on the outside of your home generates electricity from light -- electricity that can be used to power the appliances and equipment on the inside.
A team of researchers at the University of Notre Dame has made a major advance toward this vision by creating an inexpensive "solar paint" that uses semiconducting nanoparticles to produce energy.
"We want to do something transformative, to move beyond current silicon-based solar technology," says Prashant Kamat, John A. Zahm Professor of Science in Chemistry and Biochemistry and an investigator in Notre Dame's Center for Nano Science and Technology (NDnano), who leads the research.
"By incorporating power-producing nanoparticles, called quantum dots, into a spreadable compound, we've made a one-coat solar paint that can be applied to any conductive su***ce without special equipment."
The team's search for the new material, described in the journal ACS Nano, centered on nano-sized particles of titanium dioxide, which were coated with either cadmium sulfide or cadmium selenide. The particles were then suspended in a water-alcohol mixture to create a paste.
When the paste was brushed onto a transparent conducting material and exposed to light, it created electricity.
"The best light-to-energy conversion efficiency we've reached so far is 1 percent, which is well behind the usual 10 to 15 percent efficiency of commercial silicon solar cells," explains Kamat.
"But this paint can be made cheaply and in large quantities. If we can improve the efficiency somewhat, we may be able to make a real difference in meeting energy needs in the future."
"That's why we've christened the new paint, Sun-Believable," he adds.
Kamat and his team also plan to study ways to improve the stability of the new material.
NDnano is one of the leading nanotechnology centers in the world. Its mission is to study and manipulate the properties of materials and devices, as well as their inte***ces with living systems, at the nano-scale.
This research was funded by the Department of Energy's Office of Basic Energy Sciences.
