“…Our results fit well to an approach to pattern CIGS modules by micro‐welding using a comparable fs laser reported in literature . The authors found that adjusting the laser parameters correctly will partly remove the CIGS and create some well around this patterning line (P2).…”

Local electric defects may result in considerable performance losses in solar cells. Infrared (IR) thermography is one important tool to detect these defects on photovoltaic modules. Qualitative interpretation of IR images has been carried out successfully, but quantitative interpretation has been hampered by the lack of “calibration” defects. The aims of this study are to (i) establish methods to induce well‐defined electric defects in thin‐film solar cells serving as “calibration” defects and to (ii) assess the accuracy of IR imaging methods by using these artificially induced defects. This approach paves the way for improving quality control methods based on imaging in photovoltaic. We created ohmic defects (“shunts”) by using a focused ion beam and weak diodes (“interface shunts”) by applying a femto‐second laser at rather low power on copper indium gallium selenide cells. The defects can be induced precisely and reproducibly, and the severity of the defects on the electrical performance can be well adjusted by focused ion beam/laser parameters. The successive assessment of the IR measurement (ILIT‐Voc) revealed that this method can predict the losses in Pmpp (maximal power extractable) with a mean error of below 10%.

“…The fractured molybdenum substrate (eroded) yields a poor electrical connection to the back contact of the solar cell [27,28]. Such damage suggests limiting particle velocities to below 200 m/s using a gas velocity of 270 m/s at an operating stagnation pressure of P 0 = 1.5 bar.…”

“…Efficiency measurements of fully laser scribed mini-modules had been reported by several groups (Burn et al, 2013;Murison et al, 2010;Westin et al, 2008Westin et al, , 2011. However, this approach requires the integration of the laser scribing tool into the CIGS production line or its close geographical location.…”
