Description
Technical field
The present invention relates generally to test photovoltaic device, relates in particular to a kind of at least one and at least one dismountable system and method electrically contacting of photovoltaic device realized, and this system and method is tested photovoltaic device in the mode of economy, environmental protection and safety.
Background technology
Solar cell is a kind of solid state device, and it is directly converted to electric energy by photovoltaic effect by solar energy.Solar cell assembling, for the manufacture of solar module, is also referred to as solar panel.Relating to solar power generation, is an application of the sun from solar module produce power.Photovoltaic relates to apply photovoltaic cell and produces electric technology and research field from light, although it is often considered to refer in particular to from sunlight, produces electricity.
Photovoltaic cell is also referred to as solar cell, and it is light to be converted to the semi-conducting material of electric energy.Now, the photovoltaic cell of most of commercial distributions is crystal solar cells, and it is comprised of doped silicon thin slice.In order to set up and to electrically contact with these batteries, contact is set, for example at rear portion and the top of these thin slices, there is use metal layer.Conventionally, rear portion metal layer covers whole Background Region, and top metallization layer is comprised of very narrow finger piece and two or more bus.
In order to obtain high power, solar cell interconnects and assembles solar module.These solar modules are comprised of the battery of several series connection.The metal tape that is called " lug plate " by use, is connected the metallization top of previous battery and the metallization of next battery bottom.In order the resistivity of contact to be dropped to minimum and to obtain and to cross evenly electrically contacting of whole bus, these metal tapes are welded on battery.
In the final stage of producing battery, before battery is assembled into solar module, test solar cell is to determine their quality.Existing measuring technology is assessed the characteristic of different batteries, and existing measuring technology comprises electroluminescence imaging test, shunting thermal imaging test and the test of IV curve, and while using solar simulator, battery must be electrically connected to measuring element.
Electroluminescence be a kind of be the imaging technique that utilizes the anti-principle of photovoltaic cell.Electroluminescence imaging device can be positioned among the electric contact-system for battery and camera system.Whole system must be placed in darkness, so that unique low-down intensity of electroluminescence radiation is strengthened.Without the photon conversion in electronics, but in battery, utilize electric current, in the active regions of battery, found photon simultaneously.Active regions is the whole electron surface that produces photon.Photon cannot directly leave battery, thereby because photon can be reflected around finger piece or bus from rear contact site.By using extremely sensitive digital camera, can see the photon of launching in active regions.
