Title: Solar Cell device simulation
Post by: Inaoton on April 6, 2018, 17:03

Dear ATK team
                  I want to compute device characteristics  of the whole hybrid organic-inorganic perovskite solar cell ( consisting of 4 or more layers) in ATK. Is it possible to do so?

It is impossible to say much about it without knowing the type of materials used for the layers, as well as the layer thicknesses and lateral unit/supercell dimensions.  Also,what kind of device characteristics do you want to compute?

 Each  layer has a thickness ranging from 50 to 500 nm. And primarily I want to measure the  I-V characteristics under illumination.

You can study materials of individual layers, and interfaces between the layers, but not the entire device, since that would be computationally too expensive. In fact, I do not think it makes too much sense to simulate the entire macroscopic solar cell at the atomic scale. As soon as you know microscopic, material-specific parameters of the materials and  interfaces comprising the solar cell, you may consider using these parameters as inputs for macroscopic TCAD-like models of solar cells.
