1Volume of moving object
If micro battery cells are integrated with solar cells in semiconductor structures, then miniaturization of power supplies is achieved, but efficient coupling methods between components are lacking
Solution Approach 1:
The invention divides the power supply system into separate functional modules: micro battery cell (anode, cathode, electrolyte) and solar cell, which are fabricated independently on separate substrates and then coupled together. This segmentation allows each component to be optimized independently while maintaining compact integration through the coupling structure.
2Reliability
If micro battery cells are formed on semiconductor substrate with through-silicon-via connections, then reliable electrical coupling is achieved, but manufacturing process complexity increases
Solution Approach 1:
The through-silicon-via connections and bonding pads are fabricated and positioned in advance during the micro battery cell manufacturing process, before coupling with the solar cell. This preliminary preparation of electrical connection structures ensures reliable coupling while streamlining the overall manufacturing process by avoiding complex post-assembly operations.
