The utility model relates to a non-crystal-silicon solar cell diagnosis and therapy instrument which has high cure rate and can repair the non-crystal-silicon solar cell which is not coincident with the quality request via treating in order to increase the performance of the cell and the percent of pass of the finished products. The non-crystal-silicon solar cell diagnosis and therapy instrument comprises a general circuit which is composed of an undulation generator, a DC signal generator, an undulation selecting circuit, a timing circuit and a single trigger. The utility model is characterized in that the undulation generator can generate four voltage signals with four wave shapes of a DC signal, a square wave signal, a pulsation wave signal and a serrate wave signal, When treating, only one of the four voltage signals can be selected, and eight timing sections can be selected. The utility model has the characteristics of changeable polar, and adjustable changing rate and scope, and the electric treating signal and treating time of different types can be selected and combined. The utility model can not only be used for the treating of weak light and power type non-crystal-silicon cell, but also can be popularized for other hull cells.
