Half-cell solar modules have solar cells that are cut in half, which improves the solar module`s performance and durability. Traditional 60-cell and 72-cell solar panels will have 120 half-cut cells and 144 half-cut cells, respectively. When solar cells are halved, their current is also halved, so resistive losses are lowered and the solar cells can produce more power.
Smaller cells experience reduced mechanical stresses, reaching a decreased opportunity for cracking. Half cut cell PV modules have higher output ratings and are more reliable than conventional solar panels.

Is the mobile 3D camera exclusive to Apple? Domestic Obi Zhongguang can also do it
It's highly likely that Apple's event will take place on September 12, and the buzz surrounding the new iPhones is growing stronger. Rumors about the next generation of iPhones are varied. Renowned analyst Ming-Chi Kuo has reported that Apple won't be using under-display fingerprint technology due to technical difficulties. He claims that despite its maturity, the Touch ID technology might not provide an ideal user experience if implemented under the screen. If this holds true, will Apple’s 10th anniversary of the iPhone come without some groundbreaking innovation? From Kuo’s prediction that Apple would introduce a 3D front-facing camera, to the release of the AR Kit features alongside iOS 11 in June, and the recent AR app demos by developers worldwide (like AR Measure), these announcements seem to be paving the way for a revolution in 3D camera technology in smartphones.
In particular, the 3D front-facing camera, which combines facial recognition with iris scanning for fast user authentication, could become a major highlight in both smartphones and the broader smart device sector. Whether this speculation becomes reality remains to be seen, but 3D cameras are undoubtedly the next big trend in smartphone camera technology.
What are the main 3D camera technologies?
The current three primary 3D imaging technologies are:
1) Structured Light: This projects specific light patterns onto objects and captures their reflection using a camera. By analyzing the changes in the optical signals caused by the object, the technology calculates its position and depth, reconstructing the full three-dimensional space.
2) Time-of-Flight (TOF): This uses a specialized sensor to measure the time it takes for near-infrared light to travel from emission to reception, determining the object's distance.
3) Binocular Vision: This involves using two cameras to capture images of the same object and calculating its distance based on the principles of triangulation.
As seen in the comparison chart, structured light offers the advantage of achieving comparable results to the other two 3D camera technologies at a lower cost and with less complex algorithm development.
What technology does Apple's front 3D camera use?
It's anticipated that the iPhone 8's front 3D camera will utilize PrimeSense structured light technology. Given Apple's history of keeping its technology largely proprietary since acquiring PrimeSense in 2013, the demand for structured light solutions has been monopolized globally. As domestic smartphone manufacturers grow increasingly interested in 3D camera technology, they're seeking alternative providers beyond PrimeSense.
Shenzhen Obi Zhongguang Technology Co., Ltd. has stepped into this gap! Recognized as part of the Shenzhen Peacock Plan in 2014, Obi Zhongguang’s 3D depth cameras—Astra, Astra Pro, and Astra Mini—had already achieved mass production by 2015. The company received strategic investment from MediaTek in 2016 and is now the fourth global manufacturer capable of mass-producing consumer-grade 3D sensors, following Apple, Microsoft, and Intel. Their products support multiple functionalities such as facial recognition, gesture recognition, human skeleton tracking, 3D measurements, environmental perception, obstacle avoidance, object tracking, 3D mapping, and more. These applications span across TVs, smartphones, robotics, drones, VR/AR, smart home security, automotive driving assistance, and other domains.
Recently, Obi Zhongguang is set to launch an upgraded version of their structured light 3D sensor. Compared to the initial generation, the new product is more compact, features higher resolution parameters, and consumes less power, making it suitable for mobile devices like smartphones, tablets, and laptops. This innovation is poised to significantly influence the design of mobile terminals, especially smartphones!
