Transparent photovoltaic (TPV) devices have great potential to be applied as smart windows in construction and agriculture fields. TPVs with an average visible transmission (AVT) exceeding 50% are among the strong candidates to build lighting windows since the champion efficiency has already exceeded 10%. However, it is still a challenge in TPVs that semiconductors are generally expensive and transparency is difficult to further enhance, particularly for device AVT exceeding 70%. In this work, we develop a set of fullerene-based heterojunctions to harvest the light. By utilizing the low-cost fullerene as the light-absorbing material and combining it with the transparent electrode, the fabricated TPV device can achieve an AVT of 72.1% with a PCE exceeding 1%. Notably, the device with an AVT of 82% is also successfully demonstrated. This study provides an effective approach for building low-cost and efficient TPV devices.

用于非选择性吸收透明太阳能电池的富勒烯基异质结

透明光伏（TPV）装置作为智能窗户在建筑和农业领域具有巨大的应用潜力。平均可见光透过率 (AVT) 超过 50% 的 TPV 是制造照明窗的有力候选者之一，因为冠军效率已经超过 10%。然而，半导体普遍价格昂贵且透明度难以进一步提高，尤其是器件AVT超过70%，这仍然是TPV面临的挑战。在这项工作中，我们开发了一套基于富勒烯的异质结来收集光。利用低成本的富勒烯作为吸光材料并与透明电极相结合，所制备的TPV器件可以实现72.1%的AVT和超过1%的PCE。值得注意的是，AVT 为 82% 的设备也已成功演示。这项研究为构建低成本、高效的 TPV 器件提供了一种有效的方法。
