Development of Tandem Amorphous/Microcrystalline Silicon Thin-Film Large-Area See-Through Color Solar Panels with Reflective Layer and 4-Step Laser Scribing for Building-Integrated Photovoltaic Applications
Figure 4
4-step laser scribing processes of a thin-film tandem amorphous/microcrystalline silicon color see-through BIPV solar module. The schematic diagrams illustrate (a) the growth of the reflective layer onto the glass substrate, (b) the first laser scribing process P1 on the reflective layer, (c) the growth of the TCO film onto the reflective layer, (d) the second laser scribing process P2 on the TCO film, (e) the growth of the light-absorbing film onto the TCO film, (f) the third laser scribing process P3 on the light-absorbing film, (g) the growth of the TCO film onto the light-absorbing film, and (h) the fourth laser scribing process P4 on the TCO film and the light-absorbing film.
