I'm fabricating perovskite QD solar cell, and before depositing metal electrode, I deposited MoOx about 5 nm. But I'm wondering is there any effect to QD more than metal to QD.
Hey there Guhyeon Jeong! That's a great question. MoOx, or molybdenum oxide, is often used as a hole transport layer (HTL) in perovskite solar cells to improve device performance. When it comes to perovskite quantum dot (QD) solar cells, the role of MoOx can indeed be significant.
In your case, depositing MoOx before the metal electrode is a common approach to enhance charge extraction and reduce recombination losses at the interface between the perovskite QD layer and the electrode. This can lead to improved device stability and efficiency.
However, it's essential to consider the thickness and properties of the MoOx layer. While a thin layer (around 5 nm) can effectively improve charge extraction, thicker layers may introduce undesirable effects such as increased series resistance or optical losses.
Overall, MoOx plays a crucial role in optimizing the performance of perovskite QD solar cells. By carefully controlling its deposition parameters and thickness, you Guhyeon Jeong can maximize its benefits without compromising device efficiency. Keep experimenting and fine-tuning your fabrication process for the best results!
Guhyeon Jeong Yes, as said by Kaushik Shandilya MoOx, when deposited as a 5-nm-thick layer, it can positively impact perovskite quantum dot (QD) solar cells by enhancing stability and inhibiting decomposition.
