The specific embodiment
Referring to Fig. 1; Stable state solar simulator of the present invention; Comprise simulated solar light source 1, power module 2 and dodging device 3; Simulated solar light source 1 produces and the approaching simulated solar irradiation of solar spectrum, and power module 2 links to each other with the simulated solar light source and is provided for luminous constant-current supply to the simulated solar light source, and the place ahead that dodging device 3 is arranged on the simulated solar light source projects the even light that uneven simulated solar irradiation is integrated into technical indicator up to specification on the irradiation face.
Simulated solar light source 1 comprises housing 11, supporting and positioning device 12, xenon short-act lamp display 13, a plurality of spherical reflector 14, shutter 15, a plurality of optical filter 16 and cooling mechanism 17.
On the supporting and positioning device 12 that xenon short-act lamp display 13 is installed in the housing, the simulated solar irradiation approaching with solar spectrum is provided.Xenon short-act lamp display 13 can be listed as an evenly distributed formation of xenon short-act lamp by * n capable by m, and present embodiment Fig. 2 a is depicted as 2 row * 3 row.Each xenon short-act lamp is 90 ± 15 degree to the angle of light degree of irradiation face in the array.
A plurality of spherical reflectors 14 are provided with on the irradiation face that the light that corresponding xenon short-act lamp is sent reflexes to appointment with each xenon short-act lamp 13 is supporting respectively, and the reflecting surface of spherical reflector is parabola or ellipsoid.Present embodiment adopts parabolic mirror.
Shutter 15 is arranged on the place ahead of a plurality of spherical reflectors, shutter 15 with link to each other by computer-controlled transmission device, drive its rapid switch by the computer control transmission device.Shutter has the exposure time function at interval of adjustment xenon short-act lamp irradiation irradiation face.Before the total light flux maintenance of xenon short-act lamp was constant, shutter was positioned at the dead ahead of spherical reflector all the time, and the light that xenon short-act lamp is sent can't shine on the irradiation face; After the total light flux maintenance of xenon short-act lamp was constant, computer control system was opened shutter rapidly through transmission device, and the simulated solar irradiation that xenon short-act lamp is sent shines on the irradiation face; After test finished, computer control system was closed shutter once more, thereby realized the regulatory function of simulated solar irradiation to the exposure time of irradiation face.The time of closing and opening of realizing shutter through mechanical driving device can be satisfied the long test request of photoresponse time of thin-film solar cells much larger than 100ms.When shutter is in closed condition, light source and solar cell are isolated fully, prevent that solar cell is too high because of the long temperature of exposure time, guarantee that solar cell tests in the temperature range of regulation, thereby guarantee precision of test result.
A plurality of optical filters 16 correspond respectively to the place ahead that each spherical reflector is arranged on shutter.
Among the present invention the simulated solar light source in also be provided with cooling water refrigeration mechanism (not shown come out), the side away from xenon short-act lamp that this cooling water refrigeration mechanism is arranged on shutter provides refrigeration to shutter.Behind the xenon short-act lamp electrified light emitting and shutter when being in closed condition, the cooling water refrigeration mechanism has the heat radiation refrigeration to shutter, can avoid the shutter heating serious and then influence the operate as normal of shutter.
The operation principle of stable state solar simulator of the present invention is; When large-scale solar module is tested; To xenon lamp constant-current supply is provided by power module, after xenon lamp was switched on several minutes, the luminous total flux of xenon lamp kept constant; Therefore, the solar simulator in the embodiment of the invention has good irradiation stability and repeatability.The light that xenon lamp sends is radiated on the shutter through speculum, and shutter and control system thereof can realize the open and close of shutter, and then can realize the control of light source to the exposure time of irradiation face.When shutter was opened, optical filter can be handled and revise spectrum, to obtain the simulation light near solar spectrum.The effect of dodging device is to make light homogenising more, realizes that the light on the irradiation face satisfies the test request of irradiation uniformity.Housing and supporting and positioning device have effect fixing and position adjustments to xenon lamp.Cooling fan can be realized the forced refrigeration of 1kw～10kw xenon short-act lamp, guarantees the operate as normal of xenon lamp.After test finished, shutter was closed automatically, and light can't pass through optical filter and dodging device.Because the testing time is very short, the variations in temperature of solar cell only is confined to not influence the accuracy of solar module electric performance test in the very little scope.
Fig. 2 is the display of the xenon short-act lamp among the present invention distribution map, and the display of being made up of one group of xenon lamp can realize setting the irradiation intensity on the irradiated area, and the xenon short-act lamp display can be with different arrangement mode combinations, as m capable * n is listed as.The embodiment of Fig. 2 (a) has provided one group of xenon lamp and has constituted the xenon lamp array according to the mode that 2 row * 3 are listed as.Fig. 2 (b) has provided the symmetrical distribution of every row xenon lamp, has shown the angle of pitch of 2 xenon lamps among the figure.Fig. 2 (c) has provided the symmetrical distribution of every capable xenon lamp, has shown the angle of oscillation of 3 xenon lamps among the figure.Fig. 3 is the angle of light sketch map among the present invention, and each xenon short-act lamp is 90 ± 15 degree to the angle of light degree of irradiation face in the xenon short-act lamp display.
Fig. 4 regulates sketch map for 5 frees degree of the xenon lamp among the present invention.5 frees degree of xenon lamp comprise respectively: along x axial front and back translation, along y axial left and right sides translation, along the axial upper and lower translation of z, along the angle of pitch rotation of y axle rotation and the angle of oscillation rotation of rotating along the z axle.Because xenon lamp and spherical reflector thereof have axial symmetry, therefore need be around the rotation of X axle.
