The broader impact/commercial potential of this Small Business Technology Transfer (STTR) project is the integration of energy conversion and energy storage technologies into a single ribbon called the Solar Supercapacitor (SolarCap). The innovative aspect of SolarCap technology is that it is a self-powering ribbon which can be weaved along with cotton fibers to make a fabric. Batteries are currently being employed for powering wearable electronics used in remote places during multiple day trips with limited supplies and resources. However, most batteries are heavy, have a short life span, and are expensive, and transporting them to hostile locations can be difficult and dangerous. The SolarCap ribbons will have a considerable commercial impact since it can be used to charge the wearable electronics devices while woven on the user's backpack, clothing, etc. The proposed study will answer several key scientific questions including energy storage capability, stability, charge-recharge cycle life and durability of the SolarCap ribbons. The core value of the proposed SolarCap is that it can provide soldiers, firefighters, first responders, and outdoor personals increased mobility, comfort, flexibility, and peace of mind concerning device's electrical power while in the field. It can also reduce the physical load carried by the user. This Small Business Technology Transfer (STTR) Phase I project eliminates the requirement of distinct devices for energy harvesting and storage. Using distinct devices for energy harvesting and storage can be a significant issue for those who are working at remote outdoor places. This is because, once the battery power of a device is drained, the outdoor personnel should find a place to charge the battery. The objective of this proposal is to develop a wearable self-powering SolarCap ribbon by integrating solar cells and supercapacitors on a ribbon. To accomplish this goal, a flexible perovskite solar cell (PSC) will be developed on a conductive ribbon. A hybrid supercapacitor device will be integrated with the PSC to store the harvested energy. These two devices will be so integrated that a direct electric charge transfer can take place from solar cell to the storage device. The proposed SolarCap ribbons are anticipated to deliver more than 8% solar power conversion efficiency and an energy density of more than 20WhKg -1. The size of the ribbons will be so designed to weave along with cotton filaments to make a self-powering fabric.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

这个小型企业技术转移（STTR）项目的更广泛的影响/商业潜力是将能量转换和能量存储技术集成到一个称为太阳能超级电容器（SolarCap）的条带中。SolarCap技术的创新之处在于它是一种自供电带，可以与棉纤维一起编织成织物。电池目前被用于在供应和资源有限的情况下，在偏远地区进行多日旅行时，为可穿戴电子设备供电。然而，大多数电池都很重，寿命短，价格昂贵，并且将它们运送到敌对地区可能是困难和危险的。SolarCap的光带将产生相当大的商业影响，因为它可以在编织在用户的背包、衣服等上的同时，为可穿戴电子设备充电。这项拟议的研究将回答几个关键的科学问题，包括能量存储能力、稳定性、充电-充电循环寿命和SolarCap带的耐用性。SolarCap的核心价值是，它可以为士兵、消防员、急救人员和户外人员提供更多的机动性、舒适性、灵活性，以及在野外使用时对设备电力的安心。它还可以减少用户所携带的物理负荷。这个小型企业技术转让（STTR）第一阶段项目消除了对能量收集和存储的不同设备的要求。对于那些在偏远户外工作的人来说，使用不同的设备来收集和储存能量可能是一个重大问题。这是因为，一旦设备的电池电量耗尽，户外人员应该找一个地方给电池充电。该提案的目标是通过将太阳能电池和超级电容器集成在带状上，开发一种可穿戴的自供电的SolarCap带状。为了实现这一目标，将在导电带上开发柔性钙钛矿太阳能电池（PSC）。混合超级电容器装置将与PSC集成以存储收集的能量。这两个装置将如此集成，一个直接的电荷转移可以发生从太阳能电池到存储装置。拟议的SolarCap带状预计将提供超过8%的太阳能转换效率和超过20WhKg -1的能量密度。丝带的大小将被设计成与棉丝一起编织，形成一种自供电的织物。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
