    • Nanostructures and quantum dots are used in photovoltaic cells or solar cells outside of the active layer to improve efficiency and other solar cell properties. In particular, organic photovoltaic cells can benefit. The quantum dot can absorb light which is not absorbed by the active layer and emit red-shifted light which is absorbed by the active layer. The active layer, the hole transport layer, or the hole injection layer can comprise regioregular polythiophenes. Quantum dots can form a quantum dot layer, and the quantum dot layer can be found between the light source and the active layer or on the side of the active layer opposite the light source. Quantum dots can also be used in electrode layers.
    • 纳米结构和量子点用于有源层外的光伏电池或太阳能电池,以提高效率和其他太阳能电池性能。 特别地,有机光伏电池可以受益。 量子点可以吸收不被有源层吸收的光并发射被活性层吸收的红移的光。 有源层,空穴传输层或空穴注入层可以包括区域性聚噻吩。 量子点可以形成量子点层,并且量子点层可以在光源和有源层之间或在与光源相对的有源层的侧面上找到。 量子点也可用于电极层。
