Solar Silicon Cells up to 19.5% efficiency.

Since the 1970s the National Renewable Energy Lab (NREL) has cataloged over 20 differerent type of solar cell technology. Below are some solar cell technologies:

  • traditional crystalline silicon cells
  • thin-film cells
  • single-junction cells
  • multi-junction cells
  • quantum dot cells
  • solar concentrators

These above tech have various efficiencies.Our monocrystalline solar cells have efficiencies of up to 19.5%.

What does solar efficiency rating measures the percentage of sunlight photons hitting the solar cell for a given space. Higher efficiency means that less surface area is required to to generate electricity. So a small rooftop will want to use higher efficiency panels to compensate for smaller surface area.

Thin Film Solar Cell Technology Research Aided by UniversityWafer Silicon Wafers

Researchers at the University of Oviedo have used electronic silicon wafers as the base to deposit their thin films on. These wafers had three different types of film used on them for their research purposes. The first was a Si:H layer, second a C doped Si:H layer and lastly a P type Si:H layer. These wafers and coatings have been investigated as non-hydrogenated samples.

Samples preparation: a-Si:H thin films

Three different a-Si:H thin films deposited on electronic quality Si wafers (University Wafer, USA) have been employed in this study: an intrinsic a-Si:H layer (334 ± 8 nm thickness), a B and C doped a-Si:H layer (p-a-SiC:H) (376 ± 7 nm thickness) and a P doped a-Si:H layer (n-a-Si:H) (242 ± 9 nm thickness). The thickness of the layers was experimentally determined by profilometry on cross-sectioned witness samples by using a mechanical step profilometer (Model Ambios XP1, AmbiosTechnology, USA). Moreover, a certified reference material (CRM) 13X-8110L with 1.07% of B (MBH Analytical Ltd., UK), a steel sheath coated with a 10 μm thick NiP layer with a P concentration of 6% (SWEREA-KIMAB AB, Sweden) and an electronic quality Si wafer (University wafer, USA) have been investigated as non-hydrogenated samples.
