Abstract

Considering the increase in environmental pollutants and its effects on the climate change and environment, the world community is moving towards reducing the use of fossil fuels and increasing the use of renewable energies, especially solar energy, with a great importance due to its accessibility. In this regard and to increase the efficiency of the polycrystalline and mono-like crystalline solar cells’ production line, an experimental study on the crucible sizes was conducted by Islamic Azad University, Central Tehran Branch, and important results were obtained. This experimental research was done on the 100 silicon melting furnaces (TCVP4 and TCVP5 Chambers types that crucible sizes of G5 (837x837x455mm) and G6 (1015x1015x560mm) use in them.). Following this experimental study and considering hot zone space limitation of the melting furnaces, by changing the sizes of used crucibles, the silicon block loss that was from 12.3% to 43.9% in different crucible and solar cell sizes decreased from 10.1% to 23.7%. These changes caused to improve the quality of the solar cells and increase the grade of them. Besides, by using 4,000,000kg silicon as this production line’s row material, the polycrystalline solar cells’ production efficiency that was from 744MW to 927MW during 218 to 293 working days increased from 913MW to 1048MW during 297 to 302 working days. These results are able to create considerable changes in the solar energy industry.
