Semi-transparent Organic Solar Cells

有机太阳能电池可以通过低成本的溶液工艺制造，并且能够实现高产量的片到片和卷到卷制造。最近已经实现了沿着的> 17%的串联电池的功率转换效率以及>15%的单结电池的功率转换效率。值得注意的是，有机太阳能电池具有作为半透明太阳能电池的独特潜力，半透明的有机太阳能电池已达到10%的效率，平均可见光透过率约为40%。在这项技术商业化之前，还需要进一步的研究。许多半透明有机太阳能电池使用蒸发的半透明银电极，这不适合高产量制造工艺。此外，大多数高效有机太阳能电池需要薄的光伏膜、薄的电子传输层和薄的空穴传输层（一些传输层还需要通过蒸发沉积）。因此，可扩展性目前是有限的。研究工程师将：-开发具有可调颜色的高效半透明有机太阳能电池。开发具有高电导率和高透射率的可溶液加工的厚层顶部半透明电极。开发具有良好效率和透明度的所有溶液可加工厚层器件，并演示5 cm x 5 cm可扩展的半透明有机太阳能电池。与工学院和理学院的相关研究团队合作。

Organic Solar Cells can be fabricated by solution process which is low cost and enables high throughput sheet-to-sheet and roll-to-roll manufacturing.Power conversion efficiency for single junction cell of >15% has recently been achieved along with >17% efficiency for a tandem cell.Significantly, Organic Solar cells have a unique potential as semi-transparent solar cells, as their colour can be tuned according to need.Semi-transparent organic solar cells have achieved an efficiency of 10% and an average visible transmission of around 40%.Further research is needed before the technology can be commercialised. Many semi-transparent organic solar cells use evaporated semi-transparent silver electrode, which does not suit high throughput manufacturing processes. In addition, most high efficiency organic solar cells require thin photovoltaic film, a thin electron transporting layer and a thin hole transporting layer (some of the transporting layers also require deposition by evaporation). Hence scalability is currently limited. The Research Engineer will:- Develop high efficiency semi-transparent organic solar cells with tunable colour.- Develop solution processable thick layer top semi-transparent electrode with high conductivity and transmission.- Develop all solution processable thick layers devices with decent efficiency and transparency, and demonstration of 5 cm x 5 cm scalable semi-transparent organic solar cells.- Work collaboratively with related research teams in College of Engineering and College of Science.
