A shingled PV module is manufactured by dividing and bonding. In this method, the solar cell is divided by lasers and bonded using electrically conductive adhesives (ECAs). Consequently, the manufacturing cost increases because a process step is added. Therefore, we aim to reduce the production cost by reducing the amount of Ag paste used in the solar cell front. Various electrode structures were designed and simulated. The number of fingers was optimized by designing thinner fingers, and the number of fingers with the maximum power conversion efficiency was confirmed. The simulation confirmed the maximum efficiency in the 4-divided electrode pattern. The amount of Ag paste used for each electrode pattern was calculated and analyzed. The number of fingers was optimized by decreasing the width of the finger; this will not only reduce the amount of Ag paste required but also the increase the efficiency.

The shingled photovoltaic module can be produced by joining divided solar cells into a string of busbarless structure and arranging them in series and parallel to produce a module, in order to produce a high output per unit area. This paper reports a study to optimize solar cell electrode structure for shingled photovoltaic module fabrication. The characteristics of each electrode structure were analyzed according to the simulation program as follow: 80.62% fill factor in the six-junction solar cell electrode structure and 19.23% efficiency in the five-junction electrode structure. Therefore, the split electrode structure optimized for high-density and high-output shingled module fabrication is the five-junction solar cell electrode structure.

This paper has described about principle and form of proposed circuit made use of soft switching technology ZVS(Zero-Voltage-Switching) to reduce turn on and off loss at switching. Also, the analysis of the proposed circuit was described by using normalized parameter and operating characteristics has been evaluated as to switching frequency and parameters Based on the characteristics value, a method of the circuit design is proposed. The theoretical results are in good agreement with the experimental ones. The proposed circuit is consider-ated to be useful for induction heating and discharge lamp.
