Design of family laminated solar energy battery
Laminated solar energy battery generally have 10~30 layers, or even more, and their stacking is not simply overlapping, but in the process of stacking, many technical conditions need to be met, such as bandgap matching, lattice matching, optical matching, etc.…

Discussion on the Development of I-V Group Tandem Solar Cells
In the design of solar cells, spectral matching is an important issue to be considered. Single-bandgap solar cells can only absorb sunlight with a frequency greater than a certain frequency, and the absorption is not complete, which leads to low…
