Absorption Enhancement in Ultrathin Crystalline Silicon Solar Cells with Antireflection and Light-Trapping Nanocone Gratings
Solar cells light trapping antireflection crystalline silicon absorption enhancement nanocone gratings
2015/8/7
Enhancing the light absorption in ultrathin-film silicon solar cells is important for improving efficiency and reducing cost. We introduce a double-sided grating design, where the front and back surfa...
Study of surface exfoliation on crystalline silicon induced by Co-implantation of He and H ions
crystalline Si He and H ion implantation surface blistering and exfoliation bubbles growth
2009/8/14
Crystalline n-type Si (100) wafers were implanted at room temperature with
160 keV He ions to a fluence of 5×1016cm－2 or 40 keV H ions to a fluence of 1×1016cm－2, singly or in combination, followed ...
Surface morphology of He-implanted single-crystalline silicon
crystalline silicon He ion implantation He bubble Cavities blisters morphology
2009/8/14
Single-crystalline Si (100) samples were implanted with 30 keV He2+ ions to doses ranging from 2.0×1016 to 2.0×1017ions /cm2 and subsequently thermally annealed at 800℃ for 30min. The morphological ch...
PECVD-ONO: A New Deposited Firing Stable Rear Surface Passivation Layer System for Crystalline Silicon Solar Cells
Silicon Solar Cells Passivation Layer System
2008/10/31
A novel plasma-enhanced chemical vapour deposited (PECVD) stack layer system consisting of a-SiOx:H, a-SiNx:H, and a-SiOx:H is presented for silicon solar cell rear side passivation. Surface recombina...
The current cost distribution of a crystalline silicon PV module is clearly dominated by material costs, especially by the costs of the silicon wafer. Therefore cell designs that allow the use of thin...
