It also minimizes heat damage to the cell, which helps maintain its structure and further improve efficiency.<\/li>\n<li><strong>High-efficiency hydrogen passivation technology:<\/strong> uses hydrogen to alter specific properties in a solar cell and repair defects. This improves the cell&#8217;s ability to hold onto electrical charge carriers for longer, thereby increasing the cell&#8217;s efficiency at converting sunlight into electricity.<\/li>\n<\/ol>\n<p>Trina claims the advantages of this tech, apart from better cell efficiency, include:<\/p>\n<ul>\n<li>Reduced degradation over time<\/li>\n<li>Reduced Light and Elevated Temperature Induced-Degradation (LeTID) &#8211; leading to fewer early failures &#8211; especially in hot climates with strong sunlight.
