"After using the equipment from Saifan, the R&D cycle of our perovskite solar cells was shortened from 18 months to 6 months, and we also saved 200,000 yuan in electricity bills!" " "The space mission was delivered three months ahead of schedule, all thanks to its ability to customize the Mars spectrum in just seven days!" " These genuine feedbacks from the photovoltaic and aerospace fields reveal the core value of Saifan Optoelectronics' solar simulators. In the current context where the "dual carbon" goals are driving the iteration of photovoltaic technology, space exploration is advancing into deep space, and scientific research and agriculture are pursuing efficient breakthroughs, Saifan, with its three major advantages of "0.3% accuracy, 11-year maintenance-free, and 72-hour customization", has become a "key partner" for various industries to break through the bottleneck of light.
I. Photovoltaic R&D: From "Waiting for Sunny Days" to "All-weather Breakthrough", Achieving a Double Harvest of Efficiency and Cost
In the past, when testing perovskite solar cells, work would be halted whenever it rained or overcast. It took half a year to accumulate a set of valid data. The monthly electricity cost for eight xenon lamp devices is 20,000 yuan. When replacing the lamps, the entire production line has to be shut down for three days. The maintenance cost alone exceeds 150,000 yuan a year. The words of Mr. Wang, the R&D director of a certain TOPCon battery enterprise, hit the pain point of photovoltaic R&D. The arrival of the Saifan solar simulator has completely freed R&D from the reliance on weather conditions.
Accuracy: Reliable data, avoiding detours in R&D
The 5th generation intelligent spectral fitting algorithm independently developed by Saifan has been trained on 2 million sets of measured data. The full-band spectral matching degree from 400nm to 1100nm has reached the A + level, and the restoration accuracy in the near-infrared region of 780nm exceeds 98%. After the Wang team operated the preset AM1.5G mode with the touch screen, the device automatically generated the IV curve. The test deviation of the same batch of batteries was reduced from ±0.8% to ±0.3%. "Now, the data measured today can be reproduced without any problem next month, and there is no need to verify it repeatedly anymore." With the help of the equipment, they discovered the core problem of "13% lower near-infrared absorption efficiency of the battery" in just 12 days. After optimization, the efficiency jumped from 25.2% to 27.3%, and the results were published in Nature Photonics.
Cost account: 11 years of maintenance-free, saving "half a production line"
"Now we have full control over our own R&D pace. The money saved can be used to purchase two more devices, and we will be able to promote the mass production of perovskite-silicon tandem cells this year." " Engineer Wang said with a smile.
Ii. Aerospace Testing: From "Reliance on Imports" to "Domestic Customization", Reliable Even in Extreme Environments
For the test of spacecraft battery wings, if the light intensity drift exceeds 5% at a low temperature of -40℃, it is considered a scrapping data. Previously, only imported equipment could be used. The customization cycle took three months and a deposit of 2 million yuan had to be paid. The experience of Engineer Li from the Beijing Institute of Aerospace Metrology was once a common occurrence in the aerospace field. The "extreme environment adaptation + rapid customization" capability of Saifan has broken this situation.
Weather resistance: Withstands the test of space, with zero data risk
Saifan adopts the 6061-T6 military-grade body and airtight packaging, and operates stably within the temperature range of -40 ℃ to 60℃. The light intensity fluctuation in the 720-hour low-temperature irradiation test is ≤±1.2%. During the test of a battery wing on a certain space station, the team used it to precisely reproduce the AM0 space spectrum. The new anti-radiation coating they developed has extended the in-orbit lifespan of the battery wing from 5 years to 15 years. "The data is even more accurate than imported equipment, and there is no need to worry about delays at milestone nodes anymore."
Customization power: Complete the Mars spectrum in 7 days, with a 98% speed increase
During the Mars exploration mission, the R&D team of Saifan completed the design of the "AM0 + Infrared Enhancement" module in 72 hours. By increasing the density of lamp beads in the 800-1100nm band, the irradiance of this band was raised by 30%, and the installation and debugging were completed in 48 hours. "Foreign manufacturers have to wait for three months, but Saifan delivered in just seven days and saved 1.5 million yuan in customization fees. The key data of the 22% increase in the efficiency of the Mars rover's sails was all measured by it." " Engineer Li sighed.
Iii. Scientific Research Experiments: From "Seizing Time slots" to "Breaking through at Any time", the output of achievements is 50% faster
The photocatalytic hydrogen production experiment is particularly sensitive to temperature. The surface of the xenon lamp equipment exceeds 70℃, and the experimental bench gets hot, resulting in poor data repeatability. I want to adjust the proportion of ultraviolet light, but the equipment only has three fixed Settings. The experiment has been stuck for half a year without any progress. Professor Zhou from Qingdao University of Science and Technology is troubled by a common problem in the field of scientific research. The "flexible regulation + low heat generation" advantages of the Saifan solar simulator have brought new vitality to the laboratory.
Flexible regulation: 1% accuracy, unlocking more possibilities
The Saifan equipment supports 1% precision adjustment in the ultraviolet (300-400nm), visible and near-infrared bands. The light intensity can be continuously switched from 1W/m² to 1500W/m², and it can also simulate 8 scenarios such as day and night alternations and pulsed light. After Professor Zhou's team adjusted the proportion of ultraviolet light from 5% to 15%, the efficiency of photocatalytic hydrogen production increased by 40%, and the cost of green hydrogen dropped to 35 yuan per kilogram, reaching the commercialization threshold. "Experimental parameters that were previously unimaginable can now be precisely achieved."
Low heat generation: Stable environment and reliable data
Adopting the "distributed heat dissipation + microchannel water cooling" technology, the surface temperature of the equipment is only 38℃ during operation, and the fluctuation of the experimental environment is ≤±0.5℃. "Previously, students had to seize the cold period in the early hours of the morning to conduct experiments. Now, they can obtain stable data at any time, and the research progress has directly accelerated by 50%. This year, two papers have already been published in SCI." " Professor Zhou mentioned that the agricultural research group used it to simulate the strong sunlight on the plateau, and the yield of the cultivated barley varieties increased by 25%, which has been widely promoted in Qinghai.
Iv. Agricultural Planting: From "Relying on weather for harvest" to "increasing income solely through formula", farmers earn an additional 200,000 yuan annually
In winter, the greenhouses lack sufficient light, and the sweetness of strawberries is only 8 degrees. They are sold at 6 yuan per jin, and the 20 mu of land can earn less than 100,000 yuan a year. "Traditional supplementary lights burn strawberries if placed too close, have no effect if placed too far away, and the electricity cost is also high." " The predicament of Lao Yang, a strawberry grower in Shandong Province, is a microcosm of facility agriculture in the north. After introducing the Saifan solar simulator in 2023, his strawberry garden has completely transformed.
Light Formula: Precise production increase, quality upgrade
After on-site research by the Saifan technical team, they customized a solution of "65% red light + 10% blue light +2 hours of 380nm ultraviolet light" - red light promotes sugar accumulation, blue light enhances fruit firmness, and ultraviolet light increases anthocyanins. The equipment is hung 30 centimeters above the strawberries. The surface temperature of 38℃ will not burn the crops, and the uniformity of light exposure reaches 95%. After one growing season, the sweetness of strawberries rose to 11 degrees, the yield per mu increased from 2,000 kilograms to 2,150 kilograms, and the price per jin rose to 12 yuan.
Energy-saving account: Save 70% on electricity bills and earn more real money
Previously, sodium lamps were used for supplementary lighting, with a monthly electricity bill of 1,200 yuan. Now, with the Saifan equipment, it only costs 360 yuan, saving 10,000 yuan in electricity fees each year. With the increase in production and income, the annual profit of the 20 mu of land has increased by 200,000 yuan. Now, more than 10 farmers around have followed me to buy!" Lao Yang's strawberry garden has now become a "demonstration base for science and technology agriculture", and many growers often come to learn from it.
