The Technical and Economic Viability of Replacing n-type with p-type Wafers for Silicon Heterojunction Solar Cells
The cost of silicon heterojunction (SHJ) solar cells could be reduced by replacing n-type silicon wafers with cheaper p-type wafers. Chang et al. use Monte Carlo simulations to assess the commercial viability of p-type SHJ solar cells, indicating that p-type cells must have an efficiency within 0.4%abs of n-type cells.
