The solar cell is formed by the junction of n-type mono-Si and p-type mono-Si. The n-type mono-Si (in red) is the phosphorus-doped layer, while the p-type mono-Si (in aqua blue) is the boron-doped layer. The combined thickness of these layers ranges in hundreds of micrometers. The cross-sectional view of monocrystalline solar cells

The device structure of a silicon solar cell is based on the concept of a p-n junction, for which dopant atoms such as phosphorus and boron are introduced into intrinsic silicon for preparing n- or p-type silicon, respectively. A simplified schematic cross-section of a commercial mono-crystalline silicon solar cell is shown in Fig. 2. Surface
A P-type solar cell is built on a positively charged silicon base. We should note that the raw silicon material is the same for n-type and p-type solar panels. The silicon is turned into a wafer which forms the basis of the solar cell. In a p-type solar cell, the base of that wafer is coated (or doped) with boron. Boron has one less electron than silicon, meaning the base is positively charged

Mono-crystalline silicon solar cells with a passivated emitter rear contact (PERC) configuration have attracted extensive attention from both industry and scientific communities. A record efficiency of 24.06% on p-type silicon wafer and mass production efficiency around 22% have been demonstrated, mainly due to its superior rear side passivation. In this work, the
Monocrystalline silicon is generally created by one of several methods that involve melting high-purity, semiconductor-grade silicon (only a few parts per million of impurities) and the use of a seed to initiate the formation of a continuous single crystal. This process is normally performed in an inert atmosphere, such as argon, and in an inert crucible, such as quartz, to avoid impurities
Past barriers to adoption of n-type silicon cells by a broad base of cell and module suppliers include the higher cost to manufacture a p-type emitter junction and the higher cost of the n-type mono silicon crystal.
n-type mono-crystalline material to reach ~10% of the total Si solar module market by the year 2015, and over 30% by 2023 . This roadmap predicts a substantial shift from p-type to n-type mono-Si within the mono-Si material market . Past barriers to adoption of
n-type silicon cells by a broad base of cell and module suppliers include the higher cost to manufacture a p-type emitter junction and the higher cost of the n-type mono silicon crystal. Technologies to reduce the cost of manufacturing the p-type emitter by diffusion or implantation of boron are being developed in the industry .
Future high efficiency silicon solar cells are expected to be based on n-type monocrystalline wafers. Cell and module photovoltaic conversion efficiency increases are required to contribute to lower cost per watt peak and to reduce balance of systems cost.
Previous work has shown that 800 kg of n-type mono-crystalline ingot produced by CCz technology from a single crucible can be used to fabricate nPERT and n-Pasha solar cells with uniform performance despite the change of the minority carrier lifetime (MCLT) from the first to the last ingot.
The efficient use of the ingot material and high productivity of the continuous Czochralski (CCz) technology can help reduce the cost of n-type wafers which is one of the obstacles to the adoption of high performance n-type solar cells.
