This Small Business Innovation Research Phase I project will develop new soluble small molecule (SSM) architectures for organic (plastic) photovoltaic (OPV) technology. SSMs are low-cost plastic semiconductors that can be printed as an ink or spray painted onto conventional plastic sheets to fabricate extremely inexpensive, lightweight, and flexible solar cells. Development of organic solar cells has primarily been based on small molecules deposited from vapor (an expensive and constraining process) or solution-processed polymers; semiconducting polymers by nature are inherently impure and are limited to small batch sizes with inconsistencies between batches. SSM-OPV technology removes these critical development and manufacturing barriers. The overall objective is to further improve the efficiency and lifetime of already highly efficient SSM-OPVs through an approach that is expected to lead to substantially improved isotropy in the optical and electrical properties, which in turn can lead to better charge transport and enhanced efficiency. It is also expected to improve the device lifetimes by reducing degradation over time via crystallization. Therefore this project will be addressing two of the most critical barriers to the commercialization of OPV technology.The broader impact/commercial potential of this project is the promise of very low-cost solar cells that are extremely lightweight and flexible, and which are domestically manufactured via low-cost roll-to-roll processing. These plastic solar cells promise to be substantially lighter and more flexible than existing technologies, with competitive efficiencies and lifetimes for the niche portable solar market. The market for niche solar applications made from lightweight flexible photovoltaics includes stand-alone portable chargers for military and retail users as well as integrated systems including integration with tents, awnings, recreational vehicles, and tensile fabric structures. This market is relatively new and is quickly growing despite the fact the market needs are poorly met by currently available technologies. Currently available photovoltaics in the portable solar market have limited flexibility thereby increasing their collapsed volume and weight. While still new, the niche flexible solar market is predicted to surpass 32 gigawatts (GW) and $58 billion by 2019. The market for OPV stand-alone portable chargers alone is predicted to reach $222 million by 2015. There is also potential that SSM-OPV technology could make inroads into the building integrated PV (BIPV) market or the even the much larger utility scale market.

这个小企业创新研究第一阶段项目将为有机（塑料）光伏（OPV）技术开发新的可溶性小分子（SSM）架构。SSM是一种低成本的塑料半导体，可以作为油墨印刷或喷涂到传统的塑料板上，以制造极其便宜，重量轻，灵活的太阳能电池。有机太阳能电池的开发主要基于从蒸气（一种昂贵且受限的工艺）或溶液处理的聚合物沉积的小分子;半导体聚合物本质上是不纯的，并且限于小批量，批次之间不一致。SSM-OPV技术消除了这些关键的开发和制造障碍。总体目标是通过一种方法进一步提高已经非常高效的SSM-OPV的效率和寿命，该方法预计会导致光学和电学性质的显著改善的各向同性，这进而可以导致更好的电荷传输和增强的效率。 还期望通过减少经由结晶随时间的降解来提高器件寿命。因此，该项目将解决OPV技术商业化的两个最关键的障碍。该项目更广泛的影响/商业潜力是极低成本的太阳能电池的承诺，这些电池非常轻和灵活，并且通过低成本的卷对卷加工在国内制造。 这些塑料太阳能电池有望比现有技术更轻，更灵活，在小型便携式太阳能市场上具有竞争力的效率和寿命。 由轻质柔性光伏材料制成的利基太阳能应用市场包括用于军事和零售用户的独立便携式充电器，以及集成系统，包括与帐篷、遮阳篷、休闲车和拉伸织物结构的集成。 这一市场相对较新，尽管目前可用的技术很难满足市场需求，但仍在快速增长。便携式太阳能市场上目前可用的光致伸缩材料具有有限的灵活性，从而增加了它们的折叠体积和重量。虽然仍然是新的，但到2019年，利基灵活太阳能市场预计将超过32吉瓦（GW）和580亿美元。 OPV独立便携式充电器的市场预计到2015年将达到2.22亿美元。 SSM-OPV技术也有可能进入建筑一体化光伏（BIPV）市场，甚至更大的公用事业规模市场。
