High Efficiency Silicon Solar Cell

solarex16.in : High Efficiency Silicon Solar Cell

Requires: SSuprem 4/S-Pisces/Luminous
Minimum Versions: Athena 5.22.3.R, Atlas 5.28.1.R

This example demonstrates solar cell performance increase by introducing pyramids at the top of the cell. Whether or not pyramids are used as well as their height and width were parameterized in this example.

The solar cell was designed using a local back contact. This specific geometry requires 2D simulation. Athena and Devedit are used to define and mesh the solar cell.

A bell shape is obtained and for this specific case a pyramid length of around 10um gives the higher efficiency.

Simulation results show improvement of performance when pyramids are used. As an example simulations are made without and with pyramids with a length of 10um and a height of 5um. Results are shown below:

with pyramids

JscmAcm2=40mA/cm2
Voc=0.70V
FF=84%
Eff=24%

without pyramids

JscmAcm2=34mA/cm2
Voc=0.67V
FF=84%
Eff=19.35%
