This Small Business Technology Transfer (STTR) Phase I project will demonstrate a new approach to optimize thin film photovoltaic device fabrication. The requirements for the efficient conversion of solar radiation to light are a challenge to modern solid state physics and engineering. The task is to provide conversion elements, which are efficient, cheap, and long-lived in order to compete with sources of electric energy which exploit non-regenerative resources of our planet. Organic solid state devices offer severaladvantages which make them highly interesting for this area of scientific research and commercial development: (1) tunability of the absorption properties, (2) low cost of production due to the ease of fabrication and low costs for the raw materials, (3) mechanical flexibility. One could produce 10,000 m2 of active solar panels with a film thickness of the organic active layer of 100 nm using only 1 kg of organic material. Luna proposes to use an interdiffusion process to fabricate thin film, organic photovoltaicdevices that are characterized electrically and optically during the fabrication step. This unprecedented, new approach allows one to optimize device performance during fabrication and to resolve the kinetics of the chemical and physical processes which take place during the interdiffusion of two species of organic molecules.Thin film photodiodes and solar cells have immediate application in various commercial areas for inexpensive, large area, flexible optical detection and energy conversion devices in optical communications, household appliances, and commercial electronics.

这个小型企业技术转移（STTR）I阶段项目将展示一种新的方法来优化薄膜光伏设备制造。有效转化太阳辐射到光线的要求是对现代固态物理和工程的挑战。 任务是提供转换元素，这些元素有效，便宜且长寿，以便与利用我们地球的非再生资源的电能来源竞争。 有机固态设备提供了几种范围，这使得它们在科学研究和商业开发领域非常有趣：（1）吸收特性的可调性，（2）由于原材料的易于制造和低成本而导致的低生产成本，（3）机械灵活性。 只能使用仅1千克的有机材料生产10,000平方米的活性太阳能电池板，具有100 nm的有机活性层的膜厚度。 露娜（Luna）建议使用互扩散过程来制造薄膜，有机光伏电源器在制造步骤中以电和光学的特征进行特征。 这种前所未有的新方法允许人们在制造过程中优化设备性能，并解决在两种有机分子互连过程中发生的化学和物理过程的动力学。用于廉价的大面积，柔性的光学检测和能量转换设备，用于光学通信，家用电器和商业电子设备。
