Abstract

In application, the HgCdTe photovoltaic arrays exist crosstalk. There are many factors to cause it, and the surface channel is one of them. Because there are electric charges on the surface of HgCdTe photovoltaic device, they can form the surface channel between arrays. We calculate the crosstalk caused by diffusion of carrier through the surface channel under applied voltage. Using the LMC crosstalk instrument, we have measured the crosstalk. The calculative values conform to the result of experiment well. It shows that the surface channel is one of the important factors to effect the crosstalk of HgCdTe photovoltaic arrays. The thicker channel of the surface, the greater crosstalk of the arrays. The crosstalk decreases following with increasing of majority concentration.
