Abstract: The present invention relates to a method for manufacturing a CZTS-based thin film solar cell and a CZTS-based thin film solar cell manufactured by using the method. The method for manufacturing a CZTS-based thin film solar cell comprises: the step (step 1) of forming a back surface electrode on a substrate; the step (step 2) of re-crystallizing the back surface electrode by radiating an energy beam onto the back surface electrode of step 1; and the step (step 3) of forming a CZTS (Cu_2ZnSn(S,Se)_4) optical absorption layer on the back surface electrode of step 2. In accordance with the method for manufacturing a CZTS-based thin film solar cell according to the present invention, an effect arises in that an interfacial compound which may be formed between the back surface electrode and a CZTS-based thin film can be suppressed by re-crystallizing the back surface electrode, and thus the flow of holes can be improved by reducing a back surface electrode barrier and a fill factor can be improved by series resistance of a device, thereby improving the efficiency of the overall device. Furthermore, an advantage arises in that the re-crystallization of the back surface electrode is performed via an energy beam at a low temperature, and thus a substrate capable of improving the characteristics of the optical absorption layer, such as a soda lime glass substrate, can be employed.

Abstract: A current spark can be generated when a light emitting diode is dynamically reduced. The current spark can be presented by using a voltage control loop for controlling the output of an LED driver directly before a transition period. Especially, in the adjustment of an LED driver, a current control loop directly before an LED chain is reduced (for example, a control loop of adjusting the output current of an LED driver) is switched into a voltage control loop (for example, a control loop of adjusting the output voltage of the LED driver). Next, the voltage control loop reduces the voltage of the LED driver to a target voltage before the LED chain is reduced. Therefore, the LED chain can be reduced without inducing the current spark.
