Advantages and disadvantages of thin-film solar cells

You can find more information on our web, so please take a look.

Thin-film solar cells are widely used in photovoltaic agricultural greenhouses and photovoltaic facilities that require light transmission. Do you know what are the advantages and disadvantages of thin-film solar cells? How many years does this thin-film solar panel last?

At present, the existing thin-film solar cells mainly include: cadmium telluride thin-film solar cells, copper indium gallium selenide thin-film solar cells, and amorphous silicon thin-film solar cells.

1. Advantages of thin-film solar cells

(1) The value of sunlight with high absorption rate.

GaAs belongs to III-V compound semiconductor materials, and its energy gap is 1.4eV, which is just the value of high absorption rate sunlight, which is more suitable for matching with the solar spectrum.

(2) High temperature resistance.

Under the condition of 250 °C, the photoelectric conversion performance is still very good, and its highest photoelectric conversion efficiency is about 30%, which is especially suitable for high-temperature concentrating thin film solar cells.

(3) Lower cost.

Using silicon wafers as substrates, the heteroepitaxial method of MOCVD technology is a promising method to reduce the cost of GaAs cells.

2. Disadvantages of thin-film solar cells

(1) Easy deliquescent.

The growth mechanism of thin-film solar cells determines that thin-film solar cells are prone to deliquescent, so the water resistance of fluorine-containing materials required to encapsulate thin-film solar cells is about 9 times stronger than that of crystalline silicon cells.

(2) Photoinduced attenuation.

The attenuation of thin-film solar cells is about 30%.

(3) The conversion efficiency of thin-film solar cells is low.

Due to the high conversion efficiency of membrane solar cells, most of them only appear in small-scale and flexible electronic products.

(4) Cadmium telluride in the production material is a toxic substance.

Cadmium is a highly toxic substance that accumulates in the food chain like mercury, which is contrary to the concept of being environmentally friendly, safe and non-toxic. Many institutions and laboratories are looking for environmentally friendly, high-efficiency alternatives, and solar manufacturers are exploring ways to recover and recycle cadmium-containing materials to solve environmental problems.

Vancouver, BC, Feb. 01, (GLOBE NEWSWIRE) -- First Tellurium Corp. (CSE: FTEL, OTC FSTTF) (the &#;Company&#; or &#;First Tellurium&#;), reports that a recent article in Solar Power World highlights the increasing importance of cadmium telluride (CdTe) solar cells for generating solar energy and domestic security. The article also notes that demand for American-made CdTe solar is outpacing supply, with supply issues related partially to recent bans on Chinese silicon solar panels.

The article, titled &#;Accelerating CdTe Solar Panel Adoption Can Make U.S. Solar More Secure,&#; notes that CdTe solar panels are an essential part of the green energy transition, with most utility-scale projects in the United States powered by CdTe technology.

&#;Industry trends continue to support the long-term, exponential growth of cadmium-telluride solar panels,&#; said First Tellurium President and CEO Tyrone Docherty. &#;New, primary sources of tellurium will be in high demand as market coverage expands. This is why we&#;ve positioned First Tellurium to be a leader in tellurium exploration in North America.&#;

CdTe photovoltaics, a type of thin-film solar cell made from a combination of cadmium, tellurium and other materials, offers distinct advantages over traditional silicon-based solar cells. They&#;re cheaper and require less energy to produce, and they&#;re more efficient at converting sunlight into electricity. With a theoretical maximum conversion efficiency of over 31%, CdTe solar technology has yet to reach its full potential for growth.

Historically, CdTe panels have faced competition from Chinese-made silicon solar panels. However, Chinese solar companies have been connected to forced labor in the Xinjiang region, prompting the U.S. government to ban more than 1,000 shipments of solar energy components following a June law banning imports from the solar manufacturing region.

According to Solar Power World, &#;The Cadmium Telluride Accelerator Consortium (CTAC), a group of research teams, universities and companies, is working to accelerate the development of domestically manufactured, cheaper, more efficient CdTe solar cells, making American-made solar panels more affordable and accessible for consumers.&#;

&#;While solar power continues to grow as the leading use of tellurium,&#; said Docherty, &#;new technologies such as lithium-ion batteries will add to the steady rise in tellurium consumption.&#; First Tellurium&#;s strategic partner Fenix Advanced Materials and the University of British Columbia are spearheading development of tellurium use in next generation lithium-ion batteries.
