To conclude, in this article, we present a techno-economic analysis comparing the suitability of both n-type and p-type wafers for SHJ solar cells, with the aim of determining the required conditions—if they exist—in which p-type wafers would be economically advantageous.
P type wafers are extensively used in solar cells, LEDs, and as substrate material for microprocessors and ASICs. Their abundance of positive charge carriers makes them useful anywhere hole mobility is preferred. What are some common applications of N type silicon wafers?
The n-type silicon wafer still shows similar performance to the cells with defects near the E V, while the p-type cells here illustrate a reduction in the performance at the region above χ 4.05 eV in E g between 1.3 to 1.5 eV and 1.7 to 2 eV.
Much like P type wafer production, creating an N type silicon wafer starts with refining raw silicon into an ultra-pure monocrystalline form. The difference lies in which impurity gets embedded to enable negative charge carriers. Common doping techniques for N type silicon wafers include:
