Intermediate Band Solar Cells Based on Triplet-Triplet Annihilation

该项目寻求开发一种新技术，使太阳能电池能够从太阳获取更广泛的光，包括红光和红外光，以提高太阳能到电力的转换效率。有人建议，这将通过一系列化学反应来实现，这些化学反应允许通过传统方法或多步骤过程来产生电力，在该过程中，低能量的光‘胶合’在一起。这与新兴技术有关，如染料敏化太阳能电池，这些电池成本低，在建筑上有吸引力，并适合于柔性基板。预计该项目将为大幅提高太阳能电池的效率提供一种手段。

This project seeks to develop a new technology which allows solar cells to harvest a broader range of light from the sun, including red and infrared light, to increase solar-to-electric conversion efficiency. It is proposed that this would be accomplished through a series of chemical reactions which allow electrical power to be generated either by conventional means or a multi-step process in which low energy light is ‘glued’ together. This is of interest in relation to emerging technologies such as dye-sensitised solar cells, which are low cost, architecturally appealing and amenable to flexible substrates. It is anticipated that this project will provide a means for substantial improvement in solar cell efficiencies.
