“…There are two main surface-textured ZnO film deposition methods. Neither low-pressure chemical vapor deposition (LPCVD) − nor a postdeposition etching process after magnetron sputtering − is ideal for forming quality-stable ZnO films because of difficult process control. The high deposition temperature of 200−500 °C for magnetron-sputtered ZnO films is also deleterious to the device performance ,, .…”

Highly surface-textured ZnO:Al (AZO) thin films have been fabricated at room temperature by a two-step magnetron sputtering process and using an oxygen-deficient ZnO target with small grain sizes. The as-deposited AZO films are composed of a highly oriented seed layer and a closely packed columnar overlayer with pyramidal growth fronts, supporting a two-step mechanism of crystallite nucleation and grain growth. The structural, optical, and electrical properties of the AZO films can be tuned by the deposition conditions. The optimal two-step AZO film with a maximum root-mean-square roughness of 40.2 nm reaches a very low square resistance of 0.66 Ω/sq (ρ = 1.32 × 10−4 Ω·cm) with an average transparency of 87.9% in the range of 400−1100 nm. The maximum haze factor of the as-deposited film is 60.7% at 360 nm, and the average haze factor is 14.8%. These properties are comparable to or exceed the reported values of surface-textured SnO2- and ZnO-based transparent conducting oxide films, making our films suitable for transparent electrode applications, especially in thin-film solar cells.

“…The first part was for forming the seriesconnected structure by using the standard laser processes known as the P1 (ablation of the front electrode), P2 (ablation of the silicon film), and P3 (ablation of the back electrode and silicon film) scribing processes. [16][17][18][19] These scribes were carried out by backscribing [20] (through the glass side) irradiations with a 1064 nm laser for P1 and a 532 nm laser for P2 and P3 scribes.…”

The building‐integrated photovoltaic (PV) technology is one of the most promising applications for amorphous silicon (a‐Si) thin film solar cells. It is necessary to develop more various building‐integrated PV modules, which will provide architects and industries more options for the PV installation to their buildings or construction bodies. In this paper, a new type of a‐Si PV module, called image‐patterned translucent a‐Si PV module, is developed. Any required image can be displayed on the module by using laser processes. In the present result, a 5.5 generation (1100 × 1400 mm) image‐patterned translucent PV module with 10% transmittance exhibits the stabilized maximum power output (Pmax) of 92.5 W, which can be further improved by optimizing the laser parameters. The remarkable features of our module such as the image displaying, natural light transmission, and heat reduction create entirely new applications including windows and logos and provide an option that adds personal style and unique design to the building interiors.
