Production equipment technologies: manufacturing solar cells and modules from wafers

The manufacturing of solar modules can be classified into two stages – pre-cell or silicon-to-wafer stage and post wafer, that is, wafers-to-cells-and-modules. In India, however, there is very little incentive for domestic players to move into the former. This is because the pre-cell process for making wafers from silicon is highly capital intensive. Moreover, China has a stronghold in this domain. With massive investments and a dominant market share, Chinese players supply cost-effective and efficient wafers.
