High efficiency N-type multicrystalline solar cells
conference paper
Research and development activities on silicon solar cells mainly focus on cost reduction and performance optimisation. An alternative technology with a large potential regarding cost reduction and improvement of environmental footprint is n-type multicrystalline silicon solar cell technology. N-type multicrystalline silicon shows several advantages compared to p-type multicrystalline silicon. One of them is the lower sensitivity to some metallurgical impurities which is an important feature when solar cells are produced from less pure silicon feedstock. In general, high minority charge carrier lifetime and competitive diffusion length have been reported for n-type mc-Si. This paper presents a brief overview of the n-type multicrystalline silicon material properties exposed in the literature, together with the behaviour of n-type multicrystalline material at the solar cell level. Fabrication processes for high efficiency n-type multicrystalline solar cells based on industrial techniques are presented.
