A method of stabilizing perovskite ink is proposed. This method uses benzylhydrazine hydrochloride (BHC) to stabilize the organic cations of perovskite ink, and remove harmful water impurities, while also reducing iodine back to iodide as has already been discovered. The downstream products of BHC and iodine are investigated via 1D and 2D NMR spectroscopy and found to be chemically benign. All scalable perovskite solar cells are made with BHC ink and found to have nearly 20 % efficiency.

苄肼对可扩展钙钛矿前驱体油墨的多重稳定作用，以提高钙钛矿太阳能电池的产量

提出了一种稳定钙钛矿墨水的方法。该方法使用盐酸苄肼（BHC）来稳定钙钛矿油墨的有机阳离子，并去除有害的水杂质，同时也将碘还原成碘化物，正如已经发现的那样。通过一维和二维核磁共振波谱研究六六六和碘的下游产品，发现其化学性质是良性的。所有可扩展的钙钛矿太阳能电池均采用 BHC 墨水制成，效率接近 20%。
