Low cost plastic solar cells

太阳能代表了一种有吸引力的解决方案，以满足我们对绿色和可再生能源的需求， 同时保护环境。例如，太阳在一个小时内提供了人类 一年内消费。然而，这种技术的大规模发展在某种程度上受到限制， 安装太阳能电池板的成本相对较高。聚合物半导体被认为是最重要的 这是降低太阳能电池产生的能量的成本的有希望的方法，因为它们可以溶解在 普通溶剂，并使用低成本的卷对卷涂布技术进行处理。过去五年 见证了具有功率转换效率（PCE）的体异质结太阳能电池的重大进展 现在接近大规模商业化的阈值（PCE为8-10%，寿命为 5-10年）。为了降低塑料BHJ太阳能电池的成本，我们最近开发了一种绿色，可靠， 通用的和成本有效的聚合方法称为直接杂芳基化聚合（DHAP）。我们 成功地获得了明确的，高分子量和锡的材料，其中最 在塑料太阳能电池中研究的高效材料。在这个项目中，新的高效 半导体材料将使用直接杂芳基化聚合（但不限于）制备， 在现实生活中的塑料太阳能电池模块充分评估。该项目将有助于减少 光伏设备产生的能量的成本（低于1美元/瓦或几美分/千瓦时），并减少 温室气体排放在加拿大或世界各地。

Solar energy represents an attractive solution to fulfill our needs regarding green and renewable energy while protecting the environment at the same time. For example, the sun provides in one hour what the humanity consumes during one year. However, the large scale development of this technology is somewhat limited by the relatively high cost of an installed solar panel. Polymeric semiconductors are considered to be one of the most promising ways to lower the cost of the energy generated by solar cells since they can be solubilized in common solvents and processed using low-cost roll-to-roll coating techniques. The last five years have witnessed significant advances in bulk heterojunction solar cells with power conversion efficiency (PCE) approaching now the threshold values for large-scale commercialisation (a PCE of 8-10% with a lifetime of 5-10 years). In order to keep the cost of plastic BHJ solar cells down, we recently developed a green, reliable, versatile and cost effective polymerization method called Direct Heteroarylation polymerization (DHAP). We successfully obtained well-defined, high molecular weight and tin free materials which are among the most efficient materials actually studied in plastic solar cells. During this project, new highly efficient semiconducting materials will be prepared using Direct Heteroarylation Polymerization (but not limited to) and fully evaluated in real-life plastic solar cells modules. This project will contribute to both the reduction of the cost of the energy produce by photovoltaic devices (below 1$/Watt or few ¢/kWh) and to the reduction of greenhouse gas emissions in Canada or worldwide.
