Solland Solar will enable the solar energy sector to take a major step forwards with its new Sunweb cell. By concentrating the generated energy to the back of the cell, Sunweb can offer a 2 percent higher output per cell.

Processed and connected in a solar module, the output even increases to 9 percent. This is a substantial improvement for the sector.

"Metal Wrap Through"
Sunweb is the outcome of years of intensive research and testing by the R and D division of Solland Solar in collaboration with ECN (Energy research Centre of the Netherlands).

Sunweb transfers the collected energy at the front of the cell via the especially developed MWT (Metal Wrap Through) method through the cell to the back of the cell.

By removing the "bus bars" from the front of the cell, the Sunweb cell has a larger surface area available for collecting (sun)light and converting it to electricity. Whereas the output of a solar module with a traditional cell is around 13.5 percent, the Sunweb cell increases this efficiency to nearly 15 percent. A substantial improvement in output.

Grid Parity
For many areas in the world, Sunweb's combination of increased efficiency and lower cost price means one further step towards grid parity. This is the point where the price of solar electricity is the same or lower for consumers as/than traditional electricity from oil, coal and gas.

Organisations like the IEA (International Energy Agency) estimate that grid parity will become feasible in many parts of Europe (including the Netherlands) within the next 5 to 10 years. This will make solar energy an economic alternative for fossil fuels a lot sooner than many people realise.

'Backsheet Foil'
Solland is currently working with third parties on the development of a special back-sheet foil to connect the Sunweb cells at the back. This will enable further automation of the production process, saving time and cost in the manufacturing of solar modules.

Module manufacturers
The PV sector is already showing a strong interest in the Sunweb cell. Major solar module producers are currently investigating how they can adapt their production process to allow for the short term incorporation of the Sunweb cell in their solar modules.

Solar energy can meet all the world's energy demands: expert

Madrid (AFP) Sept 5, 2008
The world must speed up the deployment of solar power as it has the potential to meet all the world's energy needs, the chairman of an industry gathering which wrapped up Friday in Spain said.
