Highly purified silicon represents up to 40 percent of the overall costs of conventional solar-cell arrays so researchers have long sought to maximize power output while minimizing silicon usage. Now, a team at MIT has found a new approach that could reduce the thickness of the silicon used by more than 90 percent while still maintaining high efficiency.
