Status and Tendency of High Efficiency n-type Silicon Solar Cells

A hot topic in photovoltaic area is to significantly improve solar cell efficiency and lower the cost from solar power. N-type crystalline Si is of particular interest for application in high efficiency solar cells due to its great advantages, such as high minority carrier lifetime, low light-induced degradation and potential high efficiency. In this paper, progresses in research and development and mass production of n-type Si solar cells with IBC, PERT, HIT, PERL and standard structures are reviewed. Research directions of high efficiency n-type Si solar cells are presented.
