AI Technical Summary

Problems solved by technology

In the process of converting light energy into electricity, if the chip is too large, the current will be too large through the high-power concentrated energy. When the light energy is converted into electrical energy through the multi-PN junction battery, the temperature of the multi-PN junction battery will inevitably rise. It is necessary to set up a heat dissipation mechanism to dissipate heat. Increasing the heat dissipation mechanism will inevitably lead to an increase in production costs and a decrease in the production efficiency of components, and will affect the stability of product components, etc., and ultimately affect the mass production of products to the market.

Moreover, in the principle of high-power concentrating light, the thermal electron dissociation and molecular vibration (rotation) kinetic energy level cause the reduction of the energy gap and the reduction of the open circuit voltage, because the increase in temperature will also narrow the depletion region of the multi-PN junction, and the capacitive effect Reduced, so the open circuit voltage is reduced, so it has a greater impact on the overall module power output
