How do tandem solar cells work?
Unlike single solar cells, tandem cells stack different materials together. This lets them absorb more types of sunlight. The trick is the order in which these cells are stacked. The top layers handle blue light, then green and red light are absorbed below. This way, all the sunlight that hits the cells is used efficiently to make power.
