What are N-type solar ?
Currently most of the crystalline solar cells are p-type. This is because of a lower cost of production of p-type. The reasons are probably attributable to history of development of solar cells. But performance wise, n-type solar cells can give much better efficiency compared to p-type solar cells. Two main factors account for this. Firstly, p-type material has boron (trivalent) doping. In the presence of light and oxygen boron undergoes some undesirable action, which reduces efficiency of conversion. This is called Light Induced Degradation or LID.
