Thin Film PV is composed of thin layers of
semi-conductor materials grown on a glass or flexible substrate
In contrast to traditional crystalline silicon PV that is cut from solid crystalline material, Thin Film PV is composed of thin layers of semi-conductor materials grown on a glass or flexible substrate and sandwiched between front and back contacts.
Features and benefits of Thin Film PV include:
- Extremely lightweight
- Durable and weather resistant
- Teflon coated and self-cleaning
- Bonds to TPO or PVC roofing
- Works well on curved roofs and walls
- Easy to install using common roofing techniques and PV and roofing can be installed at the same time
- Great in hot climates such as Australia
- Performs better in low light conditions compared to monocrystalline and polycrystalline modules
EXAMPLES OF THIN FILM PV AND DETAILS ON PERFORMANCE
Our Thin Film PV laminate utilises unique triple junction solar cells. Each cell absorbs the blue, green and red light of the sun through the three layers of the cell.
Thin Film PV laminate produces energy when sun is low in the sky, through cloud cover and when installed at non-ideal angles to the sun’s path.
Cells are connected to each other via bypass diodes. Therefore, if one cell is shaded or soiled, only the power output of this one shaded cell is lost, usually less than 4.5%.
In conventional crystalline panels, cells are connected across a string. If one cell is shaded or soiled, the power output of the total string is lost, usually 30% or more.
