1.Strong Light Absorption

CIGS PV draws on the best characteristics of copper, indium, gallium, and selenium. It absorbs light over the widest spectral range, not only within the visible light spectrum in the same manner as crystalline silicon and amorphous, but also absorb light in the infrared range, from 700-1,200 nm. This means that CIGS PV can capture light for a longer period of time during a given day, a crucial advantage for high latitudes and altitudes where sunlight may be limited, or for short winter days.

2.Stable Energy Generation

Crystalline silicon PV exhibits light diffusion and photo deterioration when exposed to the sun for long periods of time, thus causing their power generation capability to gradually decline. CIGS PV does not suffer from these phenomena. Thus, from the long-term perspective, CIGS PV offers more stable energy generation and requires less maintenance costs.

3.High Transfer Efficiency, High Overall Electrical Output

According to the National Renewable Energy Labs (NREL), CIGS PV can currently attain up to a 19.9% efficiency rate. However, the highest rate recorded in the industry has been up to 16%, with an average rate of 12%. It is worth noting that when crystalline silicon (efficiency of 16%) and CIGS are tested together outdoors, the latter generates 1.2 times more energy than the former. Even though the current in use CIGS PV’s efficiency be lower than that of silicon-based, CIGS PV absorbs more sunlight per day and so produces more energy in total.

4.Low Production Costs

The main cost of CIGS PV lies in its raw materials—copper, indium, gallium and selenium. However, it requires only ordinary soda glass as opposed to special ultra-white or thin-film conductive glass. While the aforementioned metals are precious metals, CIGS PV requires no more than a 3 um (1 um = 1/1000mm) coat, giving it a competitive per unit cost.

5.Short Energy Payback

 Time Renewable energy offers many benefits. However, manufacturing the technology to produce such energy is itself resource-intensive. Thus, in assessing whether a particular type of renewable energy is genuinely sustainable, one needs to look at not only its efficiency but also how long it takes for the renewable energy produced to offset the resources needed to produce that facility. This is known as “EPBT”(energy payback time). According to the U.S. Department of Energy, assuming a 30-year lifespan for solar installments, the EPBT of crystalline silicon PV has been estimated to be about 2-4 years. By contrast, CIGS PV is estimated only  1-2 years. In other words, any of the PV systems above mentioned would have a roughly 26-29 year lifespan of truly pollution-free use. In a nutshell, CIGS comes out on top.
