Selenium-Silicon Tandem Solar Cell
Solar energy is a cornerstone of our sustainable energy future, and thankfully, solar cells are highly efficient. In fact, mass produced solar cells routinely reach above 80% of their theoretical maximum efficiency, but that also means that they can't get much better without a radical change._x000D_ _x000D_ By combining two solar materials in a stack, a tandem solar cell can give significantly higher efficiency than a regular solar cell. This decreases land requirements and cost for sustainable solar power. SelSiCell will use a combination of the most well-known solar material (silicon) and the world's oldest solar material (selenium). A selenium-silicon tandem cell should not cost much more than a standard solar cell to produce, require only tiny amounts of extra materials, while boosting the limiting efficiency from below 30% to ultimately above 40%. This should make the selenium-silicon an attractive candidate for next-generation solar cells for ultra-large scale global deployment.
