Some ideas transform not only ways of thinking - but also the market. By using less silicon, our efficient thin-film modules not only conserve resources, they are also less vulnerable to raw material shortages in the marketplace.
Efficient thin-film modules from HelioSphera Solutions Ltd. deliver module performance similar to crystalline. Also, given unique design properties -- such as a higher output in low-light situations, a lower vulnerability to deviations of azimuth and tilt angles, and a lower temperature coefficient -- our modules are suitable for use in traditionally unusable areas.
These advantages also improve performance on partially shaded surfaces, resulting in higher output using the lower cost production methods of thin-film modules. In crystalline solar cells the light energy is absorbed within a thin surface layer (ca. 10 µm) while using a total thickness of approximately 180 µm of material. The Micromorph Technology from HelioSphera Solutions Ltd. needs only 3 µm to absorb a similar amount of light energy with no other silicon required. The costly cutting of the relatively thick crystalline silicon blocks is eliminated as micromorph silicon is coated directly onto the glass surface.
A solution for a sustainable future!

| What is "Si" technology? |
|
Apart from oxygen, silicon is the most abundant element on the surface of the earth. It almost always occurs in oxidized form as silicon dioxide, as sand or quartz. It is a non-toxic material and is possibly the most studied material in the history of mankind.
Advantages of thin-film Si technology
- Unrestricted availability of raw materials
- Significantly lower silicon use
- No need for cell assembly
- Suitable for architectural applications

| Micromorph technology |
|
| What is micromorph? |
|
| The thin-film cell, unlike the simple amorphous version, has a dual structure with an amorphous and microcrystalline silicon layer. The initial production steps, the TCO coating of the glass and creation of the amorphous layer of the top cell, are similar to those of the amorphous technology. A second layer of microcrystalline silicon is then deposited after the amorphous layer. The back contact, lamination, and protective glass cover are then identical to the conventional production process.
|
|
| Why micromorph? |
|
The dual semiconductor layer structure makes optimal use of the sun's light spectrum because the two silicon layers convert a bigger part of the light into electricity. The amorphous layer is sensitive to the visible range of the solar radiation, while the microcrystalline layer converts the infrared part of the spectrum into electricity. As a result a module based on micromorph technology is 50% more efficient than a module based on the conventional amorphous technology.
Micromorph technology is based on environmentally friendly, non-toxic abundant materials. micromorph modules require two to three years to deliver the energy consumed for their production.
