Solar panel companies turn to silicon because it is efficient and lasts a long time. A single panel lasts for at least 25 years, providing more than 80% of its initial power.
Despite the benefits, crystalline silicon is difficult to produce, which slows down the solar panel manufacturing process. In the past year, the cost of silicon has skyrocketed, up to a 300% increase, and the U.S. banned imports from China (due to a violation of international standards on child labor) — making it the second most abundant element on the planet an actual scarcity.
Alternative semiconductors: Some companies are ditching silicon for, a cheaper alternative. If they can commercialize low-cost films, the solar industry would change dramatically.
