N2 - Photovoltaic (PV) has been considered to be one of the most quickly developing renewable energy technologies in recent years. Among others, Cu(In,Ga)Se2 (CIGS) thin film architecture has shown great promise owing to its high efficiency at low material cost and its compatibility with various engineering platforms. To upscale into module level which will provide desired voltage and power outputs, laser scribing technology has been actively developed taking number of advantages over mechanical scribing, including reliable and precise scribing capabilities due to non-contact processing nature. This study focuses on the manufacturing of build-integrated photovoltaic (BIPV) based on CIGS thin film in two different ways; fabrication on flexible substrates that will be attached to the arbitrary building surfaces, and fabrication of see-through patterns on conventional glass substrate. The key laser processing parameters are controlled by nanosecond and picosecond pulsed laser sources, and strategies to achieve desired scribing quality are discussed in conjunction with fundamental laser processing mechanisms, highlighting relevant thermomechanical aspects and suppression of unwanted phase change in CIGS material systems.
