Thin film solar panel VS Crystalline silicon solar panel

【Abstract】

  Solar panels have a long history, but they are still in the development stage for a long time. When the sun shines on the solar panel, it will generate electric charge, and the photovoltaic effect will appear. The amount of charge depends on many factors: battery material (silicon, thin film, etc.), battery area, and the quality of the light source. There are different types of solar panels on the market. We can analyze thin-film solar panels and crystalline silicon solar panels to help you choose solar panels better.

1. In terms of nature:

Crystalline silicon solar panel: the most widely used solar panel, mainly because of the stability of crystalline silicon, the efficiency can reach 15%-25%. Crystalline silicon relies on mature process technology based on large amounts of data, and has generally proven to be reliable.

Thin-film solar panels: using waste silicon wafers, considering its efficiency level, silicon wafers are not necessarily low-cost. Thin-film solar panels are cheaper than traditional solar panels, but the efficiency is also lower, and the photovoltaic conversion rate is between 20%-30%.


2. In terms of characteristics:

Crystalline silicon solar panels:

Usually there are two types of crystalline silicon: monocrystalline silicon and polycrystalline silicon. Monocrystalline silicon comes from a high-purity single crystal, cut from a wafer with a diameter of 150mm and a thickness of 200mm. Polycrystalline silicon is more popular and has a larger production volume. For example, the silicon is cut into strips and then cut into wafers. The manufacturing process of polycrystalline silicon solar cells is similar to that of monocrystalline silicon solar cells, but the photoelectric conversion efficiency of polycrystalline silicon solar cells must be reduced. The photoelectric conversion efficiency is about 15%.


Thin-film solar panels:

completely different from the production method of crystalline silicon solar cells, the process is greatly simplified, the consumption of silicon materials is small, and the power consumption is lower. Its main advantage is that it can generate electricity in low light conditions. However, the main problem of amorphous silicon solar cells is that the photoelectric conversion efficiency is low. The international advanced level is about 10%, and it is not stable enough. As time goes by, its conversion efficiency decreases.


3. Thin-film solar panels VS crystalline silicon solar panels

Crystalline silicon solar panels:

Advantage:

①High conversion efficiency, reaching 12%-24.2%, high stability, easy manufacturing, and high reliability.

②Long production time and mature technology, monocrystalline silicon solar panels can withstand harsh environments and can be used for space flight.

③ Including heat resistance and low installation cost.

④Considering the waste/recycling time, silicon wafers are more environmentally friendly.

Disadvantages:

      The cost is relatively high, and the solar energy absorption factor is very low, and the material is brittle and fragile.


Thin film solar panels:

Advantage:

       Thin-film solar cells are cheaper than silicon wafer solar panels, can be prepared on thin silicon wafers, and are more flexible and easier to handle. And compared with crystalline silicon, it is not easily damaged by external shocks.

Disadvantages:

   Low efficiency, which can offset its price advantage in some applications. Its structure is also more complex, and flexible thin-film batteries require special installation skills, so at least they cannot be used in aerospace at present.


【Conclusion】

        Today, it may be felt that in the current market, thin-film solar panels are not only catching up with crystalline silicon solar panels, but will surpass crystalline silicon in all aspects, including price and efficiency, but it will still take a long time to achieve may. As far as the current situation is concerned, you can choose the solar panel that suits you according to each person's different usage.
