What is it about?

Recently, ternary solar cells have attracted much attention due to enhanced photon harvesting by using absorption spectral or energy level complementary materials as the second donor or acceptor based on a single bulk heterojunction structure. For better promoting the development of ternary solar cells, we summarize the recent progress of ternary solar cells and try our best to concise out the scientific issues in preparing high performance ternary solar cells.

Why is it important?

We first pay more attention on the fundamental physical principles that govern the photovoltaic process in ternary solar cells and the corresponding characterization techniques, such as charge transfer, energy transfer, and parallel-linkage or alloy model. We then discuss and summarize the advantages of ternary solar cells according to the latest literature studies, like efficient strategies for enhanced photon harvesting, phase and morphology adjustment, crystallinity forming and device stability. The current challenges and further prospects on ternary solar cells are also briefly analyzed in the last section.
