Advancements in n-Type Base Crystalline Silicon Solar Cells and Their Emergence in the Photovoltaic Industry

Abstract EN

The p-type crystalline silicon wafers have occupied most of the solar cell market today.

However, modules made with n-type crystalline silicon wafers are actually the most efficient modules up to date.

This is because the material properties offered by n-type crystalline silicon substrates are suitable for higher efficiencies.

Properties such as the absence of boron-oxygen related defects and a greater tolerance to key metal impurities by n-type crystalline silicon substrates are major factors that underline the efficiency of n-type crystalline silicon wafer modules.

The bi-facial design of n-type cells with good rear-side electronic and optical properties on an industrial scale can be shaped as well.

Furthermore, the development in the industrialization of solar cell designs based on n-type crystalline silicon substrates also highlights its boost in the contributions to the photovoltaic industry.

In this paper, a review of various solar cell structures that can be realized on n-type crystalline silicon substrates will be given.

Moreover, the current standing of solar cell technology based on n-type substrates and its contribution in photovoltaic industry will also be discussed.
