SBIR Phase I: Nanostructured Hybrid Organic-Inorganic Solar Cell

这个小型企业创新研究第一阶段项目建议将重点放在开发和光电优化一种新型跨越式网状涂层太阳能电池的原型上，这种电池具有柔韧性，重量轻，单位面积的绝对成本大大降低，并且具有突破性的性价比。该项目的目标是创造和优化具有效率的台式原型设备，这将代表有机电池中最高的太阳能电池效率。该项目的塑料太阳能电池是基于一个200纳米厚的纳米级电荷分裂网络，作为一个活性层，从溶液中自组织成高度规则的涂层，可以定制以吸收大部分可见光光谱。这些太阳能电池可以涂在大面积的面板上，而不需要使用光刻、真空沉积或高温工艺。在商业上，相对于最佳实践太阳能电池，基于薄膜，无机铜铟镓硒化技术，这种新方法有可能使太阳能电池的每瓦成本比2008年业界预期的基于cigs的电池性能高2.5倍，这是一个前所未有的水平，有可能使太阳能电力在经济上可行，并有广阔的市场。此外，该技术还具有重量轻、形状灵活、单位面积成本低等特点，开辟了新的市场和应用领域。

This Small Business Innovation Research Phase I project proposes to focus on the development and optoelectronic optimization of a prototype for a new, leapfrog class of web-coatable solar cells which are flexible with a light weight form factor, have substantially lower absolute cost per area, and a breakthrough cost-performance. The objective of the project is the creation and optimization of a benchtop prototype device with an efficiency, which will represent the highest solar cell efficiency ever achieved in an organic cell. The project's plastic solar cells are based upon a 200 nm thick, nanoscale charge-splitting network which serves as an active layer, self-organized from solution into highly regular coatings that can be tailored to absorb most of the visible light spectrum. These solar cells can be coated onto large-area panels without the use of lithography, vacuum deposition, or high-temperature processes. Commercially, relative to best practice solar cells, based on thin film, inorganic copper indium gallium selenide technology, this new approach has the potential to enable solar cells with a cost per watt that is 2.5x superior to the industry's anticipated CIGS-based cell performance in 2008, an unprecedented level with the potential of making solar electricity economically feasible for a broad market. In addition, with key differentiating attributes including light weight, a flexible form, and a low cost per area, the technology opens up new markets and application segments.
