Abstract
The utility model discloses a prismatic focusing type photovoltaic power generation device, which mainly comprises a convex lens, a triangular prism and a solar cell module which are sequentially arranged on an optical path, wherein convergent light at the focal point of the convex lens enters one lateral surface of the triangular prism; and light with the wavelength being 0.4-1.2 micrometers, which is emitted by the triangular prism, radiates on the solar cell module. By adopting the light splitting mode of the triangular prism, the photovoltaic power generation can be carried out on light of which the maximum sensitivity of the wavelength responding to a silicon solar cell spectrum is 0.8-0.95 micrometers and light with other wavelengths radiates plants for photosynthesis, so that solar energy can be fully utilized.
Description
Technical field
The utility model relates to a kind of photovoltaic power generation apparatus, particularly a kind of focus prism formula photovoltaic power generation apparatus.
Background technology
Growing along with social production, in continuous growth, the energy crisis in the global range becomes increasingly conspicuous to the demand of the energy.Traditional energy, especially coal, oil, natural gas three macrofossil dyestuffs are limited especially, use traditional energy unreasonably, and they will be on the verge of exhaustion in 21 century, produce energy crisis, also can cause the global environment problem.Therefore the application of natural energy generation technology is subjected to more and more general attention, and clean cheap solar energy just is being suitable for as reproducible alternative energy source.
Solar cell can change luminous energy into electric energy, is different but the luminous energy of different wave length changes the ratio of battery into, and this character is called the spectral effects of solar cell.The solar spectral effect can be divided into absolute spectral response and relative spectral response.The unit radiation luminous energy of various wavelength or corresponding photon incide on the solar cell, will produce different short circuit currents, and short circuit current is called the absolute spectral response (is unit with A/W) of this solar cell with wavelength change.Short circuit current ratio peaked with it (normallized current) is called the relative spectral response of this solar cell by the distribution of wavelength.The solar cell kind is a lot, at present in the product still based on silicon solar cell, silicon solar cell has different sensitivity to the incident light of different wave length, the solar radiation wave-length coverage that can produce photovoltaic effect is 0.4～1.1 micron, and the peak response of silicon solar cell spectral response is 0.8～0.95 micron.
Solar power system is made up of solar panel, controller for solar, storage battery, when being alternating current 220V or 110V as out-put supply, also needs to dispose inverter, and solar panel is the core in the solar power system.At present, because the efficient of solar cell lower (general monocrystalline silicon commercialization battery efficiency is between 13～17%), therefore when building the solar power plant, need to install large-area solar cell cell panel, like this, the back side of solar cell cell panel is caused plant to carry out photosynthesis and can't be made full use of luminous energy because sunlight (luminous energy that comprises the part wavelength that can't carry out photovoltaic generation) is blocked.
Summary of the invention
The utility model provides a kind of focus prism formula photovoltaic power generation apparatus, and purpose is to solve the problem that existing photovoltaic power generation apparatus can't make full use of luminous energy.
For achieving the above object, the technical solution adopted in the utility model is: a kind of focus prism formula photovoltaic power generation apparatus, mainly form by convex lens, prism and solar module, described convex lens, prism and solar module set gradually on a light path, the focus place of described convex lens converges the side that light enters prism, and the wavelength that prism penetrates is that the irradiate light of 0.4-1.2 micron is on solar module.
Related content in the technique scheme is explained as follows:
1, in the such scheme, described prism is located at the focus place of convex lens.
2, in the such scheme, the wavelength that described prism penetrates is that 0.8～0.95 micron irradiate light is on solar module.
Because the technique scheme utilization, the utility model compared with prior art has following advantage:
1, because the utility model adopts the mode of convex lens optically focused, after therefore converging with it to light when carrying out photovoltaic generation, efficient is higher.
2, because the utility model adopts the mode of prism beam split, to the peak response of silicon solar cell spectral response is that 0.8～0.95 micron wavelength carries out photovoltaic generation, and photosynthesis is carried out in shining of other wavelength on the plant, so solar energy is fully utilized.
