Since last year, the industry thought that silicon materials would increase in price, and finally began to “grab the show” in the near future. Data show that the price of polysilicon materials has soared recently, and the density of single crystal materials has risen by more than 10%.
This has overwhelmed the most closely related silicon wafer companies. Even though the wafers are processed into thin slices, they still cannot amortize costs and can only take the road of rising prices.
OFweek Veken believes that the price increase of silicon materials will eventually be transmitted to the modules, which will affect the annual photovoltaic installations in the short term. However, in the long run, it will certainly promote the development of other low-silicon, even non-silicon solar cells.

At present, more attention is paid to thin-film solar cells and perovskite solar cells.
Among them, the thin-film battery is to prepare a layer of thin film into a solar battery, which uses very little silicon, making it easier to reduce costs. Although it sounds forward-looking, it is not far from our lives.
The more familiar American company First Solar is a photovoltaic company with profound knowledge in the field of thin-film cells. Its module shipments in 2020 have also entered the top ten, and it is also the photovoltaic company that is most hopeful of making a breakthrough in the field of thin-film cells.
Perovskite solar cells belong to the third generation of solar cells, and their advantages are high conversion efficiency upper limit and extremely low cost. However, the disadvantage is also very obvious, that is, the stability is poor. Although many scientific research teams have announced that they have developed perovskite solar cells with a conversion efficiency of more than 20%, they rarely mention key stability issues. Hope that as technology advances, a breakthrough will be made as soon as possible.
In the long run, photovoltaics still have a very broad room for growth in the future. Therefore, companies and scientific research teams need to make breakthroughs in different technical routes to achieve greater progress. The rise in the price of silicon materials this time is also an opportunity for the development of other solar cell technology routes.
