Application of molybdenum foil in solar cell
Antimony sulfide has suitable energy gap and large absorption coefficient, and its composition phase is single, non-toxic environmental protection, low price, development prospect is huge. Because the interchain of antimony sulfide is bound by van der Waals force, it is very suitable for flexible devices. Flexible antimony sulfide battery has shown great application value in portable equipment, mobile power supply and other application fields.
At present, the conversion efficiency of antimony sulfide solar cells has been continuously broken through, but its research is based on the top lining structure of rigid substrates (such as FTO, ITO and other transparent conductive glass). Sunlight incident from one side of the glass, part of the light is absorbed by the substrate, resulting in loss, which is not conducive to the effective utilization of sunlight. The device performance is also limited by the structure of antimony sulfide device and sulfur vacancy defects in vivo, and its application in flexible electronics has not been developed.
Antimony sulfide films usually use high temperature process, so the process design and substrate selection are particularly important in flexible device applications. Molybdenum foil substrate has good thermal and chemical stability, which can not only ensure that the prefabricated layer can be annealed at high temperature and the substrate is not modified, but also has good bending property. The introduction of molybdenum foil will provide conditions for the design and preparation of flexible antimony sulfide solar cells.
Molybdenum foil is used as the flexible substrate in the flexible antimony sulfide solar cell, which can match the process of antimony sulfide solar cell very well. It has good flexibility, can realize thousands of large Angle bending, and maintain good performance, which is conducive to making portable equipment.
