Fullerene-Based Transparent Solar Cells with Average Visible Transmission Exceeding 80%

Ruiqian Meng, Qianqing Jiang, Dianyi Liu

英文摘要:

Transparent photovoltaic (TPV) devices have the great potential to apply as smart windows in the construction and agriculture field. The efficiencies of TPVs are growing up quickly in recent years and the champion efficiency even exceeds 10%. However, the transparency is still hard to further improved after the average visible transmission (AVT) achieved 73%. Each component of the TPV devices will influent the transparency of the TPV. To date, the TPV with the AVT over 80% has not been reported yet. In this work, we describe the fullerene-based highly transparent solar cells. The CuSCN/C60 heterojunction is used as the effective light absorber. By finely optimizing the thickness of fullerene films and introducing the highly transparent electrodes, the TPV exhibits the AVT up to 82% while the device efficiency is above 0.3%. This study affords a new avenue to construct highly transparent TPV device.
