Why Silicon-based Thin Film Photovoltaic Technology

Silicon based thin-film photovoltaic technology makes use of the photo-electric effect of amorphous silicon (a-Si) and micro-crystalline silicon (µc-Si) semiconductor material to generate electricity in an environmentally sustainable manner.  It compares favorably over conventional crystalline silicon PV technologies by generating more electricity (kWh) with the same installed power capacity in watts.  The following characteristics of the high-performance DuPont Apollo products make it a preferred choice in sub-tropical and tropical climates:

Superior Temperature Coefficient
DuPont Apollo silicon based thin film photovoltaic modules have a smaller temperature coefficient than that of crystalline silicon modules.  This means less output power drop given the same increase in module operating temperature.  As a result, customers end up paying less for purchasing modules to achieve similar or even higher actual power output in the field.

Exceptional Power Performance under Weak Light conditions
Silicon based thin film photovoltaic modules can generate more power than crystalline silicon modules in weak light conditions, such as overcast and rainy days, resulting in the generation of more electricity over time. The power output of Silicon based thin film photovoltaic modules  is also less affected by shading.

High tolerance to diffused light
Silicon-based thin film photovoltaic modules have better performance under diffused light than crystalline silicon modules, making them less sensitive to mounting angles, dust coverage, and module surface damage.

High absorption of blue rich spectrum contributes to higher energy output
In low-latitude regions, a higher portion of solar power falls into the blue spectrum range. The large band gap of a-Si efficiently  captures the blue photons, contributing to higher energy yield.

Higher stabilized power at high temperature environment
DuPont Apollo  modules have higher stabilized power in high temperature environments, 60ºC or above due to annealing effects.  This allows for generation of more electricity by each watt from the PV modules.

Predictable system performance ensures investment return
The reliability of a PV module is a pre-requisite to ensure a system’s energy performance over 25 years, which is crucial to realizing a solar project’s return on investment. Our modules adopt robust packaging design with reliable materials, allowing for exceptional moisture resistance and environmental stability.

No power degradation caused by EVA browning
Our modules have no EVA layer in front of the solar absorber layer, avoiding power degradation caused by EVA browning under UV light during solar irradiation.

Environmentally Sustainable PV modules
DuPont Apollo products comply with the RoHS directives.  We are fully complaint to QC 080000 in the design, development and manufacturing of our thin film photovoltaic modules.
