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

Table 1

The output power (𝑃_mpp), voltage (𝑉_mpp), current (𝐼_mpp) at the maximum peak power (mmp), open-circuit voltage (𝑉_oc), short-circuit current (𝐼_sc), and the transmittance of the visible light for see-through BIPV modules with different colors of purple, dark blue, light blue, silver, gold, orange, red, and coffee. A best-recorded regular solar module of black brown without the see-through function is listed for the purpose of comparison.
