Silicon (Si) wafer-based solar cells currently account for about 95% of the photovoltaic (PV) production and remain as one of the most crucial technologies in renewable energy. Over the last four decades, solar PV systems have seen a staggering cost reduction due to much reduced manufacturing costs and higher device efficiencies.
The world PV market is largely dominated (above 90%) by wafer-based silicon solar cells, due to several factors: silicon has a bandgap within the optimal range for efficient PV conversion, it is the second most abundant material on the earth’s crust, it is nontoxic and its technology is well mastered by chemical and semiconductor industries.
For our SHJ solar cells, 11 the corresponding total J01 surf can be suppressed down to 2 fA/cm 2, and even to below 1 fA/cm 2 in excellent cases. In this case, wafer quality will undoubtedly have a great effect on the cell efficiency.
The average value globally stands at 27.07%. The highest Si cell efficiency (30.6%) on Earth can be reached in the Nunavut territory in Canada while in the Borkou region in Chad, silicon solar cells are not more than 22.4% efficient.
