Alkaline polishing technology can reduce the cost of sewage treatment significantly while improving solar cell conversion efficiency. Third, horizontal PECVD Al2O3
Low-cost aqueous alkaline etching has been widely adopted for monocrystalline silicon surface texturing in current industrial silicon solar cells. However, conventional alkaline etching can only prepare upright pyramid structures on mono-crystalline silicon surfaces. This study demonstrates for the first time the use of ethylene glycol butyl ether (EGBE) to regulate
Alkaline texturing consists of the formation of square-based pyramids randomly distributed on the surface of the wafer. This chapter includes a detailed study of the texturing process, describing the factors, parameters, and issues involved. In addition, the texturing process is located in the whole manufacturing process of the solar cell, highlighting the importance of the previous
