Micro triple junction gallium arsenide solar cell
YIM ground-efficient JT solar cells are ideal for GPS trackers, IoT, drones and precision instruments that require efficient solar cells
1.Description
MSCM-4.5-12.5 is a miniature photovoltaic cell power generation module. It uses two aerospace triple junction Gaas solar cells with an average conversion efficiency of 29.0% (AM0, 1sun, 136.7mW/cm2, 25°C). When used on the ground, the standard design voltage is 4.5V, and the operating current is 12.5mA. It can be used as a primary power supply in the fields of wearables, Internet of Things, etc. to directly supply power to batteries and electronic products.

9.Notification
u The product is a segmented absorption and utilization of the full spectrum of sunlight, and the performance cannot be output normally under indoor LED lights, fluorescent lights and other non-full spectrum light sources;
u Product performance test should be carried out under natural light of the sun, or a simulated light source similar to natural light;
u The performance indexes listed in this manual have been obtained through rigorous testing and should be correct, but still can not guarantee the performance of the representative products in the specific working environment.
