Front and Back Contact Formation Technically, a silicon wafer is a solar cell when the p–n junction is formed, but it only becomes functional after metallisation. The metal contacts play a key role in the production of highly efficient and cost-effective crystalline Si PV cells.
However, challenges remain in several aspects, such as increasing the production yield, stability, reliability, cost, and sustainability. In this paper, we present an overview of the silicon solar cell value chain (from silicon feedstock production to ingots and solar cell processing).
Improving the efficiency of silicon-based solar cells beyond the 29% limit requires the use of tandem structures, which potentially have a much higher (~40%) efficiency limit. Both perovskite/silicon and III-V/silicon multijunctions are of great interest in this respect.
