Among PC technologies, amorphous silicon-based silicon heterojunction (SHJ) solar cells have established the world record power conversion efficiency for single-junction c-Si PV. Due to their excellent performance and simple design, they are also the preferred bottom cell technology for perovskite/silicon tandems.
This perspective focuses on the latter PC technology, more commonly known as silicon heterojunction (SHJ) technology, which achieved the highest power conversion efficiency to date for a single-junction c-Si solar cell. Moreover, the SHJ technology has been utilized in realizing world record perovskite/c-Si tandem solar cells.
Hence, the overall electrochemical properties of the B/P heterojunction have been enhanced by combining the advantages of the individual phosphorene and borophene monolayers, which guarantees the B/P heterojunction as a good candidate for the anode material used in Li-ion batteries. 1. Introduction
Among all the tested samples, the three-phase heterojunction Cu/Cu 2 O-Sb 2 O 3 -15 electrode exhibited the best catalytic performance in terms of the Faraday efficiency of CO (FE CO) (Figure S11, Supporting Information) and CO partial current density (jCO) (Figure S12, Supporting Information).
In this work, the B/P heterojunction was constructed as the lattice mismatch between the borophene and the phosphorene monolayer is very small (<4%), and it's expected to show good electrochemical performance as anode materials by combining the advantage of each monolayer.
