New fractal solar panels combine efficiency and aesthetics

Researchers from the United States have proposed a new electrode design for fractal solar panels that combines the typical aesthetic advantages of the technology with the efficiency of busbar design. The proposed pattern is based on the fractal tree structure known as H tree, or T-branching, which is a geometric shape consisting of a repeating pattern that resembles the letter H. The hybrid H-tree/busbar pattern showed power losses that are close to those of standard busbars.


German module maker increases production capacity

Soluxtec is almost trebling output capacity at its 200 MW fab in the Eifel region. The Luxembourg-owned manufacturer says it wants production capacity of 550 MW for monocrystalline PERC modules and special formats this year.

UK researchers confirm correlation between micro-cracks and hot spots in polycrystalline cells

A research team from the University of Huddersfield used electron microscopy to analyze micro-cracks in 4,000 polycrystalline silicon solar cell samples. The results showed power losses may vary from 0.9-42.8%, and increased temperatures due to micro-cracking may favor the formation of permanent hot spots in the cells.

Panasonic to use Meyer Burger’s SWCT in HIT module research

Panasonic has been improving the cost and durability of heterojunction cells for years. Meyer Burger’s smartwire connections could replace three-busbar technology and drive further advances

Debates about future demand for silver in PV continue

With silver use per cell falling as demand grows, two different consultancies have given different accounts of future demand for silver in PV applications.
