[0078] Next, the working principle and usage method of the performance test device for the photovoltaic effect nuclear battery optoelectronic conversion device provided in this embodiment will be further disclosed.

[0079] The energy conversion efficiency PCE of the photovoltaic effect nuclear battery is jointly determined by multiple factors such as the surface emission efficiency η emit of the isotope radiation source, the energy transfer efficiency η trs , the light output efficiency η r-l of the scintillator, the light transfer efficiency η l-p between the scintillator and the optoelectronic conversion device, and the optoelectronic conversion efficiency η p-v of the optoelectronic conversion device. The above relationship can be expressed by formula (1).

[0080] PCE = η emit ·η trs ·η r-l ·η l-p ·η p-v (1)

[0081] Among them, η p-v describes the maximum output power density P max of the optoelectronic conversion device and the optical power density P pe received by the optoelectronic conversion device.The ratio is mainly related to the material properties and device quality of the optoelectronic conversion device, and is the core factor affecting the performance of the radiation-induced photovoltaic effect nuclear battery.

[0082] The key role of the present invention lies in accurately measuring η of the optoelectronic conversion device p-v , open circuit voltage V OC and short circuit current I SC and other key performance indicators. During the measurement of η p-v , as Figure 9 shown, the optical power density P received on the surface of the optoelectronic conversion device pe and the light source power P l satisfy a proportional relationship, which is expressed by formula (2). In the formula, Ω represents the solid angle of the light spot at the position of the optoelectronic conversion device with respect to the light source, and is related to the aperture of the diaphragm and the spatial size; T represents the light transmittance of the light attenuation sheet; S represents the area of the light spot at the position of the optoelectronic conversion device.

[0083]

[0084] Using the performance test device for the optoelectronic conversion device of the radiation-induced photovoltaic effect nuclear battery in the embodiment to carry out the performance test of the optoelectronic conversion device of the radiation-induced photovoltaic effect nuclear battery includes two links: optical power density calibration and optoelectronic conversion device performance test, specifically as follows:

[0085] Optical power density calibration

[0086] The optical power calibration test mode is as Figure 8 shown. Use the adapter at the bottom of the second housing to tightly clamp the upper surface of the integrating sphere. The lower light passing hole of the second housing is coaxial and tightly connected to the light passing hole of the integrating sphere. Connect one end of the optical fiber cable to the optical fiber interface of the integrating sphere, and the other end to the optical fiber interface of the optical power meter. In the state where the LED light source is turned on, the optical power density P received on the surface of the optoelectronic conversion device can be measured through the optical power meter pe . Successively change the combination mode of the diaphragm aperture and the light transmittance of the light attenuation sheet to adjust and measure P pe .

[0087] Optoelectronic conversion device performance test

[0088] Keep the parameters of the light source module and the light attenuation module the same as those in the above optical power density calibration link. The performance test device for the optoelectronic conversion device of the radiation-induced photovoltaic effect nuclear battery is as Figure 1 shown. Place the optoelectronic conversion device to be tested in the device test module. The optoelectronic converter to be tested is connected to the test connector using a signal wire, and the test connector is also connected to the digital source meter using a signal wire. In the state where the light source is turned on, use the digital source meter to measure the current-voltage characteristic curve of the optoelectronic conversion device, and extract the open circuit voltage V OC and short circuit current I SC, maximum output power density P max and other key performance parameters, the photoelectric conversion efficiency η of the photoelectric conversion device p-v is equal to P max and P pe ratio.

[0089] Further change the parameters of the light source, diaphragm, and filter, and repeat the above steps 1 and 2 to obtain the performance parameters of the photoelectric conversion device under different wavelengths and light power densities.
