As the solar cell demand increased lately, the crystalline Si solar cell processing technology advances greatly. Samsung Electronics, LG Chem, and LG Electronics simultaneously conduct R&D studies upon a-Si, CIGS thin film solar cell, and crystalline solar cell. They also show R&D activities on application technologies for deposition equipments and laser equipments. Lately, laser applications in crystalline solar cell edge isolation and ID marking processes have become a standard and numerous production processes such as stringer soldering undergo developments and applications. When using a laser like "Sunweb", a crystalline solar cell which secures the best efficiency, it is expected to have effects of increased efficiency, reduced processing time, and enhanced yield. Therefore, the laser is being actively studied and developed as the next-generation technology.

In 2008, Solland Solar Cell operated Starfire project in collaboration with ECN (Energy Research Center for Netherlands) and gave birth to a high efficiency solar cell, Sunweb, by developing BSC (Back contact Solar Cell). Sunweb applies a technology to reduce a shadow low by using a special metal pattern that is different from the conventional solar cell as shown in figure 1. The application of these technologies enabled over 2% more output supply and over 9% more energy production when packaged in modules compared to the conventional cells. Solland Solar also employed a simple and efficient structure in a different type from the conventional PV modules and achieved cost-cut and efficiency enhancement. Figure 2 illustrates a structure of the high efficiency module. The conventional module is in Glass-EVA (Ethylene Vinyl Acetate)-Tabbed Solar Cells-EVA-Tedlar Back Foil structure, whereas Solland Solar' s module simultaneously prepares back sheet and EVA solar cell film, places Sunweb on top, and then stacks EVA and glass. Currently, Sunweb prepares for trial and mass production after a production in small-scale.
