Abstract

Kesterite solar cells garner significant interest due to their potential for achieving high power conversion efficiency (PCE) at a reasonable cost. The recent accomplishment of a record PCE of 15.1 %, exceeding the commercial limit of 15 %, instills researchers with considerable confidence. Here, we experimentally and theoretically demonstrate the key to improving the PCE of kesterite solar cells with the help of Python code. Improving PCE requires balancing ideality factor (A) and reverse saturation current density (J0), which means that higher PCE may also be achieved in the case of high A and J0. When designing experiments to improve the PCE of solar cells, adjusting the position (related to A) and size (related to J0) of non-radiative recombination. Moreover, we wrote Python programs to generate performance parameters and fit current-voltage curves in our research, allowing us better to understand the mechanism of solar cell performance improvement. This study provides new insights into the PCE development of Kesterite solar cells, a finding of significant importance for guiding sustainable manufacturing practices in Kesterite solar cells.
