PhD Defense: «Development of tools to improve the efficiency of hydrogenated amorphous silicon solar cells»

Pursuing a better understanding in order to obtain more efficient devices, this project studies thin-film hydrogenated amorphous silicon (a-Si: H) solar cells by two ways: simulation and characterization of these devices in real time using Sentaurus software (from Synopsys). In particular simulations search for the negative effects of series and parallel resistances in the cell’s performance, and analyze the use of other materials in the p and n layers.

The second path of the thesis was to design a device for real time characterization of the cells, developing a very fast spectral response system based on the electronic control of a group of LEDs that operate simultaneously and are focused on a small area of ​​the solar cell.
