Defects of n-type cells

The difference between n-type and p-type solar
Although the first solar cell invented by Bell Labs in 1954 was n-type, the p-type structure became more dominant due to demand for solar technologies in space. P-type cells proved to be more resistant to space

Removing the effect of striations in n-type silicon solar cells
We show that striations caused a degradation of n-type solar cell performance up to about 1% absolute. • Striations are visible as low lifetime rings in wafers near the seed

The Technical and Economic Viability of Replacing n-type
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
