Packaging structure for high-efficiency and energy-saving reflective focused type solar power generation device

Abstract

The invention relates to a packaging structure for a high-efficiency and energy-saving reflective focused type solar power generation device. The packaging structure comprises a solar power generation chip which is arranged on a reflective substrate; a focusing lens is capped on the power generation chip, and silica gel is arranged between the focusing lens and the reflective substrate; the reflective substrate is provided with a groove corresponding to the other end where the power generation chip is arranged; the reflective substrate carries out total reflection on lights that enter into the reflective substrate to the surface contacted with the power generation chip by utilizing the groove and lateral walls at two sides of the groove; fixed brackets are arranged at two ends of the focusing lens and the reflective substrate, conducting electrodes which are fixedly connected are arranged in the fixed brackets and electrically connected with the power generation chip; and conducting pins which are fixedly connected are arranged on the fixed brackets and electrically connected with the conducting electrodes. The invention has favorable heat conductivity and light transmission, utilization ratio increase of lights, low cost, long service life as well as convenient installation and use.

Description

technical field [0001] The invention relates to a packaging structure of a solar power generation device, in particular to a packaging structure of a high-efficiency energy-saving reflective focusing solar power generation device. Background technique [0002] The solar energy irradiated on the earth is very huge, and the solar energy irradiated on the earth in about 40 minutes is enough for the energy consumption of human beings all over the world for one year. It can be said that solar energy is truly inexhaustible and inexhaustible energy. Moreover, solar power generation is absolutely clean and does not produce pollution. So solar power is known as an ideal energy source. [0003] Obtaining electricity from solar energy requires photoelectric conversion through solar cells. It is completely different from other power generation principles in the past, and has the following characteristics: ①No risk of depletion; ②Absolutely clean (no pollution); ③Not restricted by geo...

AI Technical Summary

Problems solved by technology

The disadvantages are: ① The energy distribution density of irradiation is small, that is, it will occupy a huge area; ② The energy obtained is related to the weather conditions such as four seasons, day and night, and cloudy and sunny.

However, its large-area monocrystalline silicon components lead to high costs. The biggest problem here is how to reduce the amount of monocrystalline silicon used, while improving its photoelectric conversion rate, and how to reduce the price of power generation equipment per watt to 0.4 At the level of ~$1, it is enough to compete with current power generation methods
