Lina Hu, Shiqi Li, Longlong Zhang, Yifan Liu, Chenxi Zhang, Yukun Wu, Qinjun Sun, Yanxia Cui, Furong Zhu, Yuying Hao, YuCheng Wu. Unravelling the role of C60 derivatives as additives into active layers for achieving high-efficiency planar perovskite solar cells.

Can sublimed C60 improve photovoltaic performance?

We note that using sublimed C 60 provides a quite marginal Voc enhancement (<10 mV), however, it gives reproducible results in repeated processes, which will be critical to enable the industrial adoption of this technology. Fig. 4: Photovoltaic performances with contacts using sublimed C60.

How efficient is organic photovoltaic cell based on a heterojunction of pentacene?

We have fabricated an efficient organic photovoltaic cell based on a heterojunction of pentacene and C 60 . Photocurrent action spectra exhibit broad light-harvesting throughout the visible spectrum with a peak external quantum efficiency (EQE) of 58 ± 4 % at short-circuit condition.

Does vapor deposition make a perovskite photovoltaic device efficient?

In this work, we demonstrate an efficient perovskite photovoltaic device with only 1 nm C 60 deposited by vapor deposition as the electron-selective material.

What are perovskite-based solar cells?

Perovskite-based solar cells (PSCs) are emerging high-efficiency photovoltaic (PV) technologies on the verge of commercialization 1, 2.

Are perovskite/silicon tandem solar cells Universal?

We verify the universality of this behavior on perovskite/silicon tandem solar cells by demonstrating their open-circuit voltages and fill factors to remain at 1950 mV and 81% respectively, over eight repeated processes using the same sublimed C 60 source material.
