ES-30TJSC-33 is a triple junction GaAs solar cell, and its brief introduction is as follows:
Structural characteristics: Three junction GaAs solar cells are usually composed of three single junction diodes of different materials connected in series, generally including GaInP top cells, GaAs middle cells, and InGaAs bottom cells. Different layer materials have different band gaps and can absorb photons in different bands of the solar spectrum. ES-30TJSC-33 achieves a wider utilization of the solar spectrum through this structural design, thereby improving the photoelectric conversion efficiency.

Microsatellite
Cube satellites are representative of microsatellites and nanosatellites. The initial definition of a cube satellite was an external dimension of 10cm × 10cm × 10cm cube is also known as a cube satellite, consisting of multiple standard cube units (Units), such as 2U cube satellites, 3U cube satellites, 6U cube satellites, etc.
CubeSat Concept Definition
The interface between the solar panel and the satellite varies depending on the manufacturer, provided that the overall dimensions of the cube satellite comply with the specifications of the cube satellite. This product is compatible with ISIS (Innovative Solutions In Space) cubic satellite interfaces (Clyde and other standards can be customized).
