Abstract
In the evolution of single‐crystal silicon solar cells, crystallographic texturing of the cell surface using anisotropicetches was an important step in improving cell performance. Unfortunately, this technique is ineffective for polycrystallinesilicon solar cells due to generally unfavorable grain orientation. This limitation has been overcome by employing a new laser texturing technique on the top surface of a laser grooved, buried top contact polycrystallinesilicon solar cell. This approach has demonstrated an independently confirmed 16.7% (air mass 1.5, 25 °C) efficiency for a 10.5 cm2polycrystallinesilicon solar cell, the highest efficiency ever reported for a polycrystalline cell of this size.Keywords
