Solar PV as an energy source is set to increase exponentially in India in the coming decade. With the increase in consumption of solar PV power, there will be a huge thrust on solar cell manufacturing in India. Silver paste – used for the front contacts in the solar cell – is the second most important and costly raw material component in solar cell manufacturing after the silicon wafer itself. This paste, owing to the technical complexity and heavy IP involved, is not produced in India making us heavily reliant on imports. India, at present, imports several tons of silver paste annually which is worth tens of crores of rupees per year. This number will grow multi-fold in the coming decade. High dependence on imports makes solar cell manufacturing in India totally uncompetitive. It is evident that this paste needs to be developed indigenously which would then secure the supply chain for solar cell manufacturing in India.
