Today, with the rapid development of science and technology and industry, light, as a key element, profoundly influences the innovation process in numerous fields. However, the uncontrollability of natural light, such as the halt of photovoltaic research and development due to rainy weather, the difficulty in simulating space light in space tests, and the constraints of seasonal light changes in agricultural production, have become obstacles to the progress of many industries. For two decades, Saifan Optoelectronics has been dedicated to the field of optoelectronics. With its profound technical foundation and innovative spirit, it has successfully developed a solar simulator. With its outstanding features of "precision, stability, and customization", it provides controllable ideal light sources for various industries, helping to break through the limitations of light and release unlimited innovative vitality.
The precise light lays a solid foundation for photovoltaic research and development
A certain photovoltaic enterprise has been suffering greatly from the fluctuations of natural light when developing perovskite/silicon tandem cells. The efficiency data of the same batch of batteries tested at different times deviated by as much as 5%, leaving the R&D work in a state of confusion. The introduction of Saifan Optoelectronics' solar simulator is like seeing the light through the clouds.
This device is like a "precision mapping instrument of light", with a wide spectral coverage range, extending from the ultraviolet band of 400nm to the near-infrared band of 1100nm. Through the advanced 5th generation intelligent spectral fitting algorithm, various standard spectra can be precisely replicated, and the spectral matching degree reaches the astonishing A + level (0.875-1.125). Even in the near-infrared region of 780-1100nm, which is easily overlooked by traditional devices, the energy distribution can be clearly presented. In terms of stability, the light intensity fluctuation is as low as ±0.3% per hour, which means that after continuous testing for 10 hours, the change in light intensity is negligible. The spatial uniformity reaches ±2%, ensuring that every part of the battery cell can receive uniform and consistent light, effectively controlling the data deviation within 1%.
Relying on such high-precision equipment, the R&D team quickly identified the shortcomings of the battery's absorption efficiency in the near-infrared band. By specifically optimizing the material composition, they successfully increased the battery's conversion efficiency to 27.3%. The related achievements were not only published in the authoritative journal "ACS Energy Letters", but also rapidly moved towards the mass production stage. On the mass production line, an automated testing system built with 8 Saifan simulators screens batteries at an efficient speed of 60 cells per minute, significantly increasing the A-grade product rate from 88% to 94%. This has reduced the annual loss of defective products by over 16 million yuan, effectively promoting the implementation process of high-efficiency photovoltaic technology.
The light of stability safeguards space exploration
When a certain team from China's space industry was testing the flexible solar cell wings of the space station, they faced the severe challenge that traditional simulators could not adapt to extreme environments. When simulating the low temperature of -40 ℃ in space, the light intensity of the equipment fluctuates by more than 4%, which is a huge deviation from the real space light, seriously affecting the accurate assessment of the battery wing life. Saifan Optoelectronics' customized solutions have built an impregnable safety defense line for aerospace testing.
The Saifan simulator adopts a military-grade 6061-T6 aluminum alloy body, and is equipped with an airtight packaging design for the optical chamber and transmission chamber, as if covering the equipment with a sturdy "space protective suit", enabling it to operate stably within an extreme temperature range of -40 ℃ to 60℃. When simulating the AM0 spectrum in space, it can precisely eliminate the atmospheric filtering effect and highly restore the pure radiation of the sun in the universe. Meanwhile, it is equipped with a 0.1ms high-sensitivity sensor, which can correct the light intensity fluctuations in real time. Even after continuous 720 hours of low-temperature irradiation, the light intensity deviation can still be firmly controlled within ±1.2%.
It is precisely because of this outstanding stability that the team has comprehensively recorded the aging laws of the battery wing materials under strong ultraviolet and extremely low-temperature environments. The new protective coating selected has successfully extended the in-orbit life of the battery wing by three times, providing a core guarantee for the safety of the power system of the manned space program. During the Mars exploration mission, the Saifan team demonstrated a powerful rapid response capability. They customized the "AM0 + Infrared Enhancement" module in just 7 days, perfectly regenerating the surface lighting conditions of Mars. The power generation efficiency of the optimized Mars rover's solar panels increased by 22%, successfully solving the energy supply problem in deep space exploration.
The light of customization injects vitality into scientific research agriculture
When Professor Zhou's team from Qingdao University of Science and Technology was conducting research on photocatalytic hydrogen production, they urgently needed to adjust the proportion of the ultraviolet band from 5% to 15%, while enhancing the near-infrared energy. The fixed spectral mode of traditional equipment is difficult to meet this special demand. The "flexible customization" function of the Saifan solar simulator has brought new opportunities to scientific research work.
This device can be called a "palette of light", with fine adjustment of 1% accuracy in the ultraviolet, visible and near-infrared bands. The light intensity range can be freely switched from 0.1sun to 2sun, and it can simulate rich light cycles such as day and night alternation and seasonal changes. It even supports special light modes such as pulsed light and gradient light. With the help of this equipment, Professor Zhou's team precisely regulated the light parameters and successfully increased the photocatalytic hydrogen production efficiency by 40%. The related research results were published in "Applied Catalysis B: Environmental".
In the agricultural sector, the Saifan simulator also plays a significant role, becoming an "intelligent light fertilizer" for enhancing crop quality. A strawberry cooperative in Shandong Province once had strawberries with a sweetness of only 8 degrees and an average yield of less than 2,000 kilograms per mu due to insufficient winter sunlight. After the introduction of Saifan equipment, through a customized light scheme of "65% red light + 10% blue light + ultraviolet assistance", the photosynthetic efficiency of strawberries has significantly increased by 25%, the sweetness has risen to 11 degrees, the yield per mu has increased by 150 kilograms, and the annual income of 20 mu of land has increased by more than 200,000 yuan. The Yunnan flower base has cultivated blue roses with high anthocyanin content using the Saifan simulator. The flowering period has been extended by 7 days, and the market premium has reached as high as 35%, making it a popular product in the high-end floral art market.
The light of full-cycle service illuminates the entire process of innovation
Saifan Optoelectronics deeply realizes that high-quality equipment cannot do without perfect service support. For this reason, Saifan has established 7 regional spare parts centers covering the whole country, stocking over 95% of commonly used spare parts, and implementing a 7× 24-hour response mechanism to ensure that equipment failures are promptly repaired within 48 hours. For instance, a simulator on the production line of a certain photovoltaic enterprise suddenly malfunctioned. Engineers from Saifan promptly arrived at the scene within two hours and completed the repair in just three hours, effectively ensuring the smooth progress of the production tasks for the day. In response to the special needs of research institutions, Saifan offers "one-on-one" customized training services. After a certain university's laboratory purchased the equipment, engineers visited the site for three consecutive days to provide guidance, helping the team quickly master core operations such as spectral regulation and data calibration, enabling the equipment to be put into use for experiments within a week.
Today, Saifan solar simulators have successfully served over 200 customers worldwide. The repurchase rate of core customers is as high as 82%, and 85% of new customers come from recommendations from existing customers. From the efficient operation of photovoltaic production lines to the safe execution of space missions; From scientific research breakthroughs in the laboratory to the joy of harvest in the fields, Saifan Optoelectronics has always broken the shackles of light with "controllable light", enabling innovations in various fields to break free from the reliance on natural light. If your path of innovation is also plagued by the problem of lighting, then this "light" from Saifan Optoelectronics will undoubtedly be the key for you to break through the predicament and move towards success.
