United Solar (Uni-Solar) has announced that it has achieved a new cell efficiency world record of 16.3% for thin-film silicon solar technology, beating the company’s previous record of 15.4%. This initial efficiency figure was achieved on a small-area (0.25cm2) cell using a triple-junction structure, and used the company’s new Nano-Crystalline silicon technology. Independent testing of the cell will be carried out by the National Renewable Energy Laboratory (NREL).
NREL has confirmed Uni-Solar’s claimed initial conversion efficiency of 12% for a large-area encapsulated cell (400cm2) using the company’s Nano-Crystalline technology. The results of this test will be publicised at the “Thin-Film – Technological Advancements” session at the Intersolar North America Conference today by United Solar’s chairman Subendu Guha.
