This Small Business Innovation Research (SBIR) Phase I project will develop a new surface modification technique for manufacturing copper indium diselenide (CIS) thin films, an important emerging photovoltaic technology. It will eliminate present toxic processing steps involving cadmium sulfide deposition, cyanide etch, all of which have many unfavorable repercussions to the manufacturer and the environment. The key step will be to devise a simple, inexpensive process, using air and a non-toxic aqueous solution, to alter the surface properties of CIS films. This step will eliminate the need for the cadmium component, the cyanide etch and the disposal of hazardous chemicals. It will also improve the efficiency of solar cells made with inexpensive coating methods. Performance evaluation of the modified CIS solar cells will validate the new concept. This innovation is anticipated to simplify manufacturing, lower costs and improve the efficiency of photovoltaic modules.Applications for the CIS photovoltaic technology range from powering small appliances to electric utility. Non-utility applications include solar cars, building integration, mobile systems and space systems. Lower costs, fewer components and easier manufacturing could translate into a wider spectrum of commercial markets for CIS solar cells. Eliminating the toxicity issues will enhance the public perception of CIS photovoltaic technology. Its implementation will promote the market success of CIS solar cells to provide a timely solution to the nation's escalating energy and environmental problems.

这个小型企业创新研究(SBIR)第一阶段项目将开发一种新的表面改性技术，用于制造铜铟二硒(CIS)薄膜，这是一项重要的新兴光伏技术。它将消除目前有毒的工艺步骤，包括硫化镉沉积、氰化物蚀刻，所有这些都会对制造商和环境产生许多不利影响。关键的一步将是设计一种简单、廉价的工艺，使用空气和无毒的水溶液来改变独联体薄膜的表面特性。这一步骤将消除对镉成分、氰化物蚀刻和危险化学品处置的需要。它还将提高用廉价涂层方法制造的太阳能电池的效率。对改进后的独联体太阳能电池的性能评估将验证这一新概念。这项创新预计将简化制造、降低成本并提高光伏组件的效率。CIS光伏技术的应用范围从为小家电供电到电力公用事业。非公用事业应用包括太阳能汽车、建筑集成、移动系统和空间系统。更低的成本、更少的组件和更容易的制造可以转化为独联体太阳能电池更广泛的商业市场。消除毒性问题将提高公众对独联体光伏技术的认知。它的实施将促进独联体太阳能电池的市场成功，为国家不断升级的能源和环境问题提供及时的解决方案。
