Features

The proprietary manufacturing techniques we use for our Copper Indium Gallium Selenide thin film compound solar panels embody the values of green production through their low energy consumption, high efficiency, and extraordinary reliability. These processes include: Cadmium-free manufacturing techniques, the RTD rapid diffusion tempering process and equipment, the linear flow enhanced CVD process and equipment, and the higher mechanical load module structure technique and specialized waste management process. With these processes at its core, Eterbright is determined to continue innovating, never satisfied and always driven to improve, so as to further its products and contributions to the world.

Cadmium Free and Lead Free Manufacturing Techniques

The CdF® CIGS PV Module, Copper Indium Gallium Selenide Thin Film Compound Solar Module, is a proprietary technique of Eterbright. This process, known internationally under the trademark CdF®, uses our revolutionary Cadmium-free manufacturing technique: not only does it create Cadmium-free products, but it also generates zero Cadmium waste. It passes product’s RoHS certification and represents what high efficiency and environmentally conscious engineering should be in the field of thin-film solar products and technology. This is in contrast to the manufacturing methods employed in building conventional thin-film compound solar cells, such as the CdTe thin-film solar cell, or the older CIGS thin-film solar cell with CdS buffer layer; both of these technologies contain Cadmium and generate Cadmium waste in their manufacturing, which is hazardous to the environment.

Superior Power Generation Characteristics

The CdF® CIGS PV Module is capable of generating power in low-light conditions, and is therefore able to continuously supply electricity through overcast weather and the early morning and sunset—in comparison, the Crystalline Silicon solar module but not able to perform that. We employ an advanced compound crystalline technique in building the CdF® CIGS thin-film solar cell, enabling us to achieve optimal uniformity and consistency of crystallization over CIGS thin-film. This level of precision is what gives the CdF® CIGS thin-film solar cell its superiority over conventional styles of the CIGS solar cell, especially in situations where there is low light available. The opposing situation of bright light can also be a hindrance to Crystalline Silicon solar modules because it might induce a state of low power generation, because of the module thermal effect; the CdF® CIGS PV Module avoids this problem because it is minimally impacted by heat. These two characteristics of the CdF® CIGS PV Module, under the same standardized output, allow it to generate 15-20% more electricity yearly than the Crystalline Silicon solar module.

High-Impact Resistance to Wind and Snow

The CdF® CIGS PV Module applies an ultra-thin Sodium Calcium glass substrate—unique among photovoltaics—and as a result, has tremendous flexibility and stability. We have incorporated additional structural reinforcement into this module, allowing for enhanced mechanical load; our products have a wind resistance and endurance capacity of up to 2400Pa and snow resistance and endurance capacity of up to 5400Pa. This not only increases the reliability and durability of our products, but also allows them to be transported and installed in distant locations without the worry of impact and damage. These qualities make our products global leaders in the CIGS thin-film solar industry.

Ease of Installation

In contrast to the Crystalline Silicon solar module, the CdF® CIGS PV Module is minimally impacted by the direction of sun exposure, making it particularly suitable for areas where there are construction and terrain limitations. We have optimized the size and weight of the CdF® CIGS PV Module, so that the installation process is simple and safe.

Aesthetic of Royal Black Lustre

Since the CdF® CIGS thin-film solar cell can absorb a wider range of wavelengths than the Crystalline Silicon solar cell can, the CdF® CIGS thin-film solar cell maximizes the absorption of photons and minimizes the amount of reflection, generating more electricity. In addition, this exceptional absorption gives CdF® CIGS thin-film a natural Royal black lustre without any unnecessary refraction. The visual aesthetic of our products is elegant and sleek, in both large-scale power plants and as rooftop units; no longer does architecture have to sacrifice sophistication and style in the name of solar power. Our products provide a bridge between the industries of architectural design and renewable energy, merging and revolutionizing them so that the future can be both functional and beautiful.

Strong Anti-Shade Effects

The unique structural design of the CdF® CIGS PV Module allows for normal power generation even when the light reception surface is partially shaded, making it versatile and efficient in a variety of situations. In comparison, the crystalline Silicon solar module can stop operating in partially shaded conditions, creating a series connection issue; the shaded module itself can cause other modules to stop operating, and its elevation in temperature can also raise further safety concerns.

CDF Manufacturing Process

Energy Payback Time (EPT)

Energy Payback Time (EPT) means how long a PV panel takes to generate the required energy when making a PV panel. Comparing with the traditional Crystalline modules’, Nano CdF® CIGS PV panels’ EPT is obviously much shorter.
