In summary, a conductive cloth was employed as the substrate for a composite carbon film electrode in perovskite solar cells. Highly conductive metal coating and the embedded structure at carbon/conductive cloth interface assure the low resistance of carbon film electrode for large area device. In addition, the fabric nature of conductive cloth
In perovskite solar cells, the interfaces between the perovskite and charge-transporting layers contain high concentrations of defects (about 100 times that within the perovskite layer), specifically, deep-level defects, which substantially reduce the power conversion efficiency of the devices1–3. Recent efforts to reduce these interfacial defects have focused mainly on surface

Many brands of AGM batteries have a high power discharge capability, having said that it might only be 5-8 times its Amphour rating. So if a 100Ah battery refers to its ability to discharge 10 amps over 10 hours, it might also have a fast discharge capacity of 600 amps, referred to as 600CA (Cranking Amps).
