Japanese Spectral IPCE Quantum Efficiency Tester

One preface:

SM-250It is a large-scale quantum efficiency testing system launched by a well-known company, Japan Spectrometer Co., Ltd. Japan Spectral is a pioneer and professional manufacturer of spectral response measurement systems and solar simulators. Provide development and testing instruments for photovoltaic cells and panels. The product is widely used in the evaluation system of SM-250 dye-sensitized/organic thin film solar cells, one of the flagship products of major research institutions and manufacturers in Japan, in cooperation with the National Institute of Advanced Industrial Science and Technology (AIST). Our products are manufactured with high specifications and provide excellent performance. The JIS (Japanese Industrial Standards) widely used for measurement provides a system that can be used for any international measurement standard system consisting of a 300-1150nm light source and a 3/, monochromator. Internally, an electric 6-digit filter wheel is also configured to achieve high-precision measurement.

Overall system requirements:

1)Use xenon lamps exceeding 150 watts.

2)Elliptical reflector is used to introduce efficient white light into monochromators

3)Use a forced air cooling fan.

4)High stability power supply ± 1%.

5)Equipped with safety interlock function. The system function stops working with sensors or automatic system functions, and the lights will not light up. When the access door is opened, the temperature of the lights rises abnormally. Or the abnormal warning is clearly conveyed through warning lights or other means.

6)Manual shutter.

II Function:

1. Requirement for testing specification: New version of IEC-60904-8.

2. The full spectrum measurement range is 300~1150nm.

3. Same point in-situ measurement of EQE and IQE.

4. The illumination area of the system is 10 x 10mm.

5. Measurable spectral response and external quantum efficiency.

6. Automatically calculate spectral mismatch factor.

7. The following parameters can be measured by software settings (PC). The start and end wavelengths can be set to any wavelength (short ->long wavelength, long wavelength ->short wavelength). The wavelength interval can be selected (1 nanometer, 2 nautical miles, 5 nm, 10 nm, 20 nm, or 50 nm). The polarity data can be selected (P/N, N/P). The measurement mode can be selected (AC or DC). The frequency of the AC can be measured. The high-order optical filter with wavelength conversion can be selected. The shutter conversion can be selected

8. Data processing is possible. Axis: wavelength Y-axis: spectral response axis: wavelength Y-axis: quantum efficiency, short-circuit current density calculation, integrated quantum efficiency and solar spectrum.

III Features:

③ The field of monochromatic light irradiation is over 10 x 10 millimeters.

④ The monochromatic light emitted from the sample at a working distance exceeds 80 millimeters.

⑤ The height of the optical axis is 140 millimeters. The system is installed on a vertical surface for illumination.

⑥ The non-uniform illumination of light is within ± 5%.

⑦ Constant light shining within ± 1%.
