Tuning Quandum Dot Solar Cells

In July, Dr Ahmad R. Kirmani published a very interesting article the day he defended his PhD. He has worked with Quantum Dot Solar Cells at the King Abdullah University of Science and Technology (Saudi Arabia) while publishing the article I invited him to talk about: Molecular Doping of the Hole-Transporting Layer for Efficient, Single-Step-Deposited Colloidal […]

Engineering interfaces with gold nanoparticles

When discussing interfaces issues with perovskite solar cells, Prof. Iván Mora-Seró from Institute of Advanced Materials, Castelló (Spain) is one of the scientists with the stronger background. Some month ago, he explored the use of gold nanoparticles at the interface between the electron sensitive contact and the perovskite material TiO₂ in perovskite solar cells. Eliminating […]

The challenges of encapsulation

In previous articles, I presented instabilities within organic and perovskite solar cells. Most are due to the presence of water and oxygen. Therefore contrary to silicon modules, third generation solar cells degrade very fast when exposed to an oxygen and moisture atmosphere. For instance, an typical organic solar cell can degrade in just a few […]

OPV stability, an intriguing mechanical approach

Two weeks ago, we discussed the stability issues of Perovskite Solar Cells. I invite you to keep connection with stability, but with organic solar cells. I found a very interesting work combining different techniques and analysis, from Dr. Sylvain Chambon. Let’s go back to Bordeaux, the southwestern French Organic Electronics’ City where he based his […]
