A CHIP PROTECTING STRUCTURE FOR SOLAR BATTERY

摘要

A chip protecting structure for solar battery is provided, and there is a condensing mirror over the battery chip, and a portion of the transmission structure whose size corresponds to the chip is a transmission region, but on the edge of the transmission region of the condensing mirror is a reflection region; the transmission region is mat surface glass or curve surface lens. The transmission region's size is exactly corresponding to the chip's size, then the chip can collect solar beam effectively; in addition, the useless collecting beam outside the solar chip is reflected or absorbed by the reflecting region to avoid irradiating on the PCB board, which causes warming-up to make the PCB melting or broken, so that the solar battery's useful life can be effectively extended; and the mat surface treatment on the transmission region or being a optical curve lens makes the redistribution of the light irradiated in the chip by the diffused reflection through mat surface or the refraction through the curve lens, thus facilitating the uniform distribution of the light irradiated in the chip to increase the filling factor of the chip of the solar battery, and hence avoiding the fault of the solar battery so that the effective utilization of the solar battery is greatly increased.
