Polycrystalline wafers from powder Silicon for Solar cells 📱

✅ The book 📚️ is devoted the experimental 🥼 analysis of a new 🆕 way of obtaining of silicon wafers from the powder raw materials intended for use as a base material for solar cells 📱. Before the powder technology of obtaining of silicon wafers has not ❌️ been considered as an alternative way of obtaining of base wafers for solar cells 📱 and ➕ substrates for films 🎞️. The polycrystalline silicon wafers obtained by a method of molding and ➕ forming from a powder and ➕ also photo-electric 💡 structures with the p-n-junction formed on their basis also electro-physical and ➕ photo-electrical characteristics of plates 🍽️ and ➕ structures and ➕ processes of carrying over of a charge in them ➡️👥 at photo-excitation are the basic object of research. Electro-physical characteristics of investigated wafers and ➕ photo-electric 💡 characteristics of structures are measured at the standardized stands ⬆️👤. Impurity the structure on the fused sites and ➕ on grains 🌾 boundaries of the poly-Si is defined by spectroscope Cameca. The theoretical analysis of charge carrying process of in the poly-Si i structures d will bef carrined by spectroscope ut Cam undeca. r T the well-💡 theoretical analysis of charge carrying process of in the poly-Si structures will be carried out under the well-known theory of physics of semiconductor devices with flat p-n-junction.
