During the process of performance calibration of photovoltaic devices, calibration of solar light simulators, and establishment of the laboratory data traceability system, the stability, spectral matching degree and calibration accuracy of the standard cells directly determine the compliance and data credibility of the entire testing system. Ordinary standard cells on the market generally have problems such as significant light attenuation, poor sealing performance, spectral response deviation, and output parameter drift. Long-term use is prone to inaccurate benchmarks and calibration deviations, resulting in distorted efficiency calculation of photovoltaic cells, inaccurate light intensity calibration of simulators, and large dispersion of batch test data. Non-metric-level reference devices cannot meet the traceability requirements for scientific research completion, product certification, and mass production quality control, and are difficult to adapt to the strict standards of high-precision photovoltaic testing, new material research and development, and authoritative compliance acceptance. They have become the core bottleneck restricting the standardization and precision of photovoltaic precise testing.

Deeply engaged in the field of photovoltaic measurement benchmarks and precise calibration, Saifan Optoelectronics relies on mature single-crystal silicon cell screening process, vacuum sealing packaging technology, and metrological-level accuracy calibration system, and has launched the 7-SSC10A single-crystal silicon standard solar cell. As a core benchmark device in the photovoltaic testing field, with high-stability non-decaying reference output, precise spectral matching, full-sealed protection against aging, metrological-level traceable calibration, and universal compatibility with a wide range of equipment, it solves the industry pain points of large drift, easy aging, low accuracy, and inability to traceability of ordinary benchmark cells, providing compliant, precise, and long-term standardized benchmark support for solar light simulator calibration, photovoltaic device power calibration, IPCE testing, and laboratory value transfer.

Metrological-level precise calibration, building a compliant traceability benchmark

The 7-SSC10A single-crystal silicon standard solar cell strictly follows international photovoltaic measurement testing specifications. It undergoes precise calibration for each unit, strong light aging screening, and parameter stability verification before leaving the factory. Each cell has complete metrological traceability capabilities and can be directly used as a laboratory-level calibration benchmark. The output parameters of the device are precisely controllable, with minimal errors in core parameters such as short-circuit current, open-circuit voltage, and peak power. It can accurately complete light intensity calibration of the solar light simulator, irradiation accuracy calibration, parameter correction of the photovoltaic testing system, and lock the benchmark accuracy of the entire set of testing equipment from the source.

Different from ordinary civilian standard cells, this product has undergone strict parameter screening and stability iteration, with extremely high value consistency, batch deviation control, and no benchmark offset or parameter jump over a long period of use. It perfectly adapts to scenarios with high precision and compliance requirements such as university scientific research data traceability, third-party testing institution compliance acceptance, enterprise mass production process benchmarking, and high-end photovoltaic device precise calibration.

Native single-crystal silicon material, spectral highly matched to standard sunlight

The battery is made of high-purity single-crystal silicon substrate, with spectral response characteristics highly compatible with conventional crystalline silicon photovoltaic devices, perfectly matching the AM1.5G standard sunlight spectral response range. The spectral matching error is extremely low, and it can accurately replicate the photoelectric conversion characteristics of conventional photovoltaic cells. Compared with thin-film and polycrystalline reference cells, the single-crystal silicon material has more uniform response and wider band compatibility, which can eliminate calibration errors caused by spectral mismatch to the greatest extent, ensuring the authenticity and accuracy of simulator calibration, sample testing, and efficiency calculation.

The response wavelength band covers the core range of photovoltaic testing, has excellent photoelectric conversion linearity, and outputs linearly stably within the conventional irradiation intensity range, without saturation distortion or response offset. It can be adapted to weak light, standard light intensity, and strong light multi-condition calibration and determination, fully covering the benchmark calibration requirements of crystalline silicon cells, high-efficiency tandem cells, and photovoltaic modules. Its versatility and compatibility are fully demonstrated.

Vacuum full-sealed packaging, long-term anti-decay stable output

The product adopts industrial-grade full-sealed vacuum packaging technology. The core battery chip is placed in the center of the high-precision anodized aluminum base, combined with a high-transparency radiation-resistant glass window and special optical sealing glue for packaging and molding. The overall structure is sealed to prevent dust, moisture, oxidation and ultraviolet aging. It can effectively isolate the erosion and damage of air, dust, humidity and light aging on the chips, completely solving the problems such as oxidation and blackening, efficiency decline and parameter drift caused by the long-term exposure of ordinary standard batteries.

After long-term strong light aging pre-treatment, the performance of the device has stabilized at the factory. After being put into use, there is almost no initial light attenuation, and the output parameters during the entire life cycle are stable and the reference is constant. It can be long-term adapted to the routine lighting use of the laboratory, frequent calibration operations, and all-weather standby conditions. There is no need for frequent re-checking and calibration, which significantly reduces the calibration frequency and operation costs of the equipment, and realizes a stable and accurate benchmark output effect after one configuration.

The precise structure design is suitable for multi-scenario standardized operations.

The battery adopts a 20mm×20mm standard universal size, with a compact and regular structure and precise positioning, suitable for the installation reference of most solar light simulators, IV testing systems, IPCE testing equipment, and photovoltaic characterization platforms, ready for immediate use and convenient alignment. The standardized aluminum base has strong rigidity, is not prone to deformation, and has excellent insulation and heat dissipation performance, which can effectively avoid the influence of temperature drift and electromagnetic interference on the reference parameters, ensuring the consistency of calibration in different environments and different working conditions.

The equipment is equipped with dedicated connection leads and calibration certificates, with clear parameter information, complete value traceability, and can be directly used for laboratory system certification, project conclusion review, product compliance testing. The installation operation is extremely simple, no complex debugging is required, and beginners can quickly complete the equipment calibration and benchmarking work, significantly improving the efficiency of laboratory standardized operations.
