In this thesis, the heterojunction with intrinsic hydrogenated amorphous silicon thin layer ( heterojunction with intrinsic thin layer: HIT) solar cells are investigated. The solar cell structure of p/i/n are fabricated. The substrate is a typical 4-inch n-type wafer with (100) crystal orientation, 1~10 ohm-cm and about 525 μm thickness. The p and i a-Si:H layers are deposited by a 13.56 MHz plasma enhanced chemical vapor deposition. The i a-Si:H layers are especially deposited by pulse-wave modulation plasma technique with fixed plasma turn-off time toff = 10 ms and changed plasma turn-on time ton= 10 to 40 ms to selectively control the different silicon to hydrogen bonding configurations. The effect of various Si:H bonds on the performance of HIT solar cells are explored.

In general, the layered feature of electrical structure is analyzed first of all for defining preliminarily whether a DES exists in the target area or not. Then the contours of resistivity in resistivity tomogram are analyzed from the deep to the shallow part. If they extend upwardly from the deeper part to shallower one and shape into the integral dislocation, great flexure or gradient zone, it would indicate there exists the DES reflecting a buried fault. At last, horizontal tracking needs to be carried out for defining the trend of the DES reflecting a buried fault.

一般情况下，在分析时，首先分析电性结构的层状特征，以此初步判定探测区域中是否存在电性结构间断面；其次，要由深入浅分析电阻率等值线，如果它们能够从探测剖面的深部向上延伸到浅部，且存在等值线的整体性错断、强烈弯曲或梯度带，则表明存在表征隐伏断裂的电性结构间断面；最后需进行水平追踪分析，以确定表征隐伏断裂的电性结构间断面的空间展布。
