Large-scale preparation of 22.06% efficiency single-crystalline silicon solar cells with inverted pyramid microstructure through nanostructure rebuilding treatment

Fabrication of 20.19% Efficient Single-Crystalline Silicon Solar Cell with Inverted Pyramid Microstructure.

This paper reports inverted pyramid microstructure-based single-crystalline silicon (sc-Si) solar cell with a conversion efficiency up to 20.19% in standard size of 156.75 × 156.75 mm2. The inverted pyramid microstructures were fabricated jointly by metal-assisted chemical etching process (MACE) with ultra-low concentration of silver ions and optimized alkaline anisotropic texturing process. An...

Efficiency improvement of crystalline silicon solar cells

To increase the efficiency and reduce the production cost of crystalline silicon (c-Si) solar cells, efforts in the photovoltaic industry are currently put on the process optimization of the cell. Sodium hydroxide/Potassium hydroxide (NaOH/KOH) and isopropyl alcohol (IPA) are widely used in the standard alkaline texturization of mono crystalline silicon (mc-Si) wafers for enhancing the optical ...

Crystalline Silicon Solar Cells

Front page headlines in the New York Times and the Wall Street Journal in 1954 heralded to the world the demonstration of the first reasonably efficient solar cells, an event made possible by the rapid development of crystalline silicon technology for miniaturised electronics. Since that time, the majority of solar cells fabricated to date have been based on silicon in monocrystalline or large-...

Effect of Silicon Nanowire on Crystalline Silicon Solar Cell Characteristics

Nanowires (NWs) are recently used in several sensor or actuator devices to improve their ordered characteristics. Silicon nanowire (Si NW) is one of the most attractive one-dimensional nanostructures semiconductors because of its unique electrical and optical properties. In this paper, silicon nanowire (Si NW), is synthesized and characterized for application in photovoltaic device. Si NWs are ...
