The troughs concentrate sunlight onto a receiver tube that is positioned along the focal line of the trough. Sometimes a transparent glass tube envelops the receiver tube to reduce heat loss .
Multi-junction solar cells were originally designed, and are still used today, for space applications. Using high-efficiency, small solar cells paired to less expensive optics made from glass or acrylic allows for a reduction in the amount of expensive semiconductor material while retaining superior performance.
The resulting solar modules are highly efficient and allow the generation of electricity at a lower cost than traditional silicon solar panels. A Fresnel lens can be made from many materials but the most popular for concentrator photovoltaic applications are acrylic or silicone on glass SOG.
Suncore went the extra mile by developing the required optics manufacturing processes and now produces the SOG lenses in house. Solar Cell Multi-junction solar cells use multiple solar cells each stacked on top of one another.
Each of these solar cells in the stack are tuned to a specific wavelength of light to maximize the conversion efficiency of incoming light into electricity. The conversion of a wider solar spectrum into electricity is key to gaining higher solar cell efficiencies. Conventional single layer silicon solar cells will never be as efficient as a multi-junction semiconductor.
Currently, most multi-junction concentrator solar cells consist of 3 cells but scientists are currently working on 4 and 5 junction solar cells to reach even higher efficiencies.
The middle diagram shows the portion of the incoming solar radiation used by a conventional PV SI cell, while the right diagram shows the portion of the incoming solar radiation used by our triple junction CTJ cells: Direct sunlight is the light that reaches the ground when there are no clouds to scatter the light.
In order to capture the direct sunlight and concentrate it into a single point over the cells, CPV modules must be pointed towards the sun.
High efficiency is one of the main methods for reducing the cost of solar power.
Less modules, less space, more savings! Yes, you can make power by placing a solar panel on the ground, but peak power can only be achieved by pointing that module at the sun as it crosses the sky!
CPV achieves this by the use of tracking systems, which provide more consistent power output throughout the day. This means more energy generation during the peak hours of the day when electricity consumption is at its highest. CPV uses dual axis tracking systems to precisely follow the sun within 1 degree of its current position, ensuring maximum sunlight to electricity conversion.Using the sunâ€™s energy to heat water is not a new idea.
