Efficiency:
Rapid progress:
Perovskite solar cells have witnessed a remarkable leap in efficiency in a short span. Just a decade ago, their power conversion efficiency (PCE) stood at around 3.8%, but it has skyrocketed to a record-breaking 27.53% for single-junction devices and 29.8% for tandem perovskite-silicon devices as of January 2022. This is comparable to the efficiency of established silicon solar cells, which typically range from 15% to 22%.
Tunable properties:
The perovskite material offers fascinating flexibility. By tweaking its composition, scientists can adjust its light absorption properties, allowing it to capture a broader range of the solar spectrum and potentially boost efficiency further.
Tandem potential:
Perovskites can be stacked with other photovoltaic materials like silicon in tandem structures. This approach leverages the complementary light absorption characteristics of each material, pushing the overall efficiency beyond the limits of single-junction devices.
Performance:
High open-circuit voltage (Voc):
Perovskites demonstrate remarkable voltage generation capability, leading to higher Voc values compared to other technologies. This translates to a larger potential difference for driving current in the solar cell.
Good charge carrier transport:
The perovskite material exhibits efficient movement of light-generated electrons and holes within its structure, minimizing energy losses and enhancing current generation.
Scalability:
Compared to silicon solar cells, perovskites offer the advantage of solution-processable fabrication techniques. These methods are potentially less expensive and more suitable for large-scale manufacturing, paving the way for cost-effective solar energy production.
