The champion efficiencies of n/p-type solar cells based on the TOPCon concept have been boosted to 25.8% and 26.1%, respectively, outperforming the conventional passivated emitter and rear contact (PERC) devices, thanks to the efforts of the photovoltaic community worldwide , .
The p-type mc-Si covered 20%, n-type mono-crystalline covered 12%, p-type mc-Si covered 23%, and p-type mono-like Si covered 3% of the total solar cell market. The increase in n-type Si solar cells was from 0% in the year 2000 to 12% in the year 2016.
The superior crystal quality of high-performance multicrystalline silicon (HP mc) in combination with the inherent benefits of n-type doping (higher tolerance to common impurities) should allow the fabrication of high-efficiency solar cells also on mc silicon.
N-Type technology refers to the use of phosphorus-doped silicon as the base material for solar cells, which inherently has a negative (n) charge due to the extra electrons provided by phosphorus. This contrasts with the more common P-Type silicon, doped with boron, which has a positive (p) charge due to the lack of electrons.
Crystalline Si, comprising p-type czochralski (CZ) mono-crystalline Si and multi-crystalline (mc) Si, has been the mainstay in solar cell production. The first crystalline Si solar cell was made on n-type substrates in the 1950s but the p-type technology has become more dominant in the current solar cell market.
N-Type silicon cells offer a significant advantage over their P-Type counterparts due to their resilience against Light Induced Degradation (LID). LID can significantly impair the performance of solar panels by reducing their efficiency as they are exposed to sunlight over time.

A solar cell is made of two types of semiconductors, called p-type and n-type silicon. The p-type silicon is produced by adding atoms—such as boron or gallium—that have one less electron in their outer energy level than does silicon. Because boron has one less electron than is required to form the bonds with the surrounding silicon atoms, an electron vacancy or "hole" is created.

In this paper, we study a light-induced degradation (LID) mechanism observed in commercial n-type silicon heterojunction (SHJ) solar cells at elevated temperatures using dark- and illuminated annealing for a broad range of illumination intensities (1–40 kWm −2) at temperatures from 25 to 180 °C.Three key results are identified.
The shortage of the p-type silicon (Si) feedstock and the high minority carrier lifetimes in multicrystalline (mc) n-type Si reported by different authors ([1]-[3]) make n-type mc-Si solar cell fabrication more and more interesting. Given the high electronic quality of the material – that is confirmed in our studies again – the task remains to develop an adapted solar cell process.
The predicted increase in n-type silicon usage, however, was significantly overestimated, and it was pushed forward over the years in parallel with the predicted increased adoption of SHJ solar cells. Consequently, the n-type silicon market share remained stable at approximately 5% until 2018. During this period, the quality gap (e.g., minority ...
