Microwire Silicon Solar Cell with Singlet Exciton Fission
Under development · Massachusetts · Last reported May 2025
Source: pv magazine International
Scientists at MIT have designed and built a microwire solar cell that couples singlet exciton fission with silicon to potentially surpass the quantum efficiency limit of conventional PV devices. The cell features an interface based on hafnium oxy-nitride film, an aluminum oxide passivation layer, and a zinc phthalocyanine electron-donor layer to improve charge transfer and reduce recombination.
