A study on soldering characteristics of laser tabbing system for crystalline silicon photovoltaic module production

Abstract

Photovoltaic energy generation has been one of the fastest growing markets in the last years. The rising oil price, climate changes and moreover significant financial market aids in form of fed-in tariffs resulted in a growth of more than 40 % over almost the complete last decade. Most of these financial incentives include dropping fed-in tariffs in order to force the market to drop production cost consistently, which is therefore the FIGURE 1: Thin silicon solar cell (< 40 µm) with an efficiency of 20 %: Laser processes like Laser-Fired Contacts allow the manufacturing of these high-efficient next generation devices due to their selectivity, flexibility and contact-less nature. major goal in current research and development. These goals can be achieved in two main ways:
