In the realm of thin-film solar cell technology, the optimization of sheet resistance through laser scribing stands as a critical factor in enhancing power conversion efficiency (PCE) and ensuring module reliability.
This comprehensive review of laser scribing of photovoltaic solar thin films pivots on scribe quality and analyzes the critical factors and challenges affecting the efficiency and reliability of the scribing process.
Nonetheless, laser scribing is a promising technique for commercializing new generations of solar cells, including perovskite, which requires further investigation due to its compositional complexity. 3. Scribing Processes in Thin Film Solar Cell Manufacturing 3.1. Fabrication and Patterning of Solar Thin Films
Solar cell efficiency testing after laser scribing Complete working solar cells of prefabrication stage with the average efficiency of 10.7% and the active surface area of 32 cm 2 were scribed using optimal single and multi-pass scribing parameters. The total length of laser scribes was 360 mm in all cases.
Laser fluence is another key parameter that significantly impacts the quality and efficiency during solar thin film laser scribing. Inadequate laser fluence can result in poor-quality scribes, including surface bulging, while excessive fluence can damage the back contact layer due to overheating and nonlinear absorption.
Efficiency of thin-film solar cells with a large active area might be maintained if small segments are interconnected in series in order to reduce photocurrent in thin films and resistance losses, and laser scribing is crucial for performance of the device.
