Iain A. Wright, in Polyhedron, 2018 Bulk heterojunction (BHJ) solar cells have been developed intensively over the last two decades due to the cheap, flexible devices which may be obtained, although their efficiency remains below that of other emerging solar cell technologies such as dye-sensitized and perovskite solar cells.
Ordinary heterojunction solar cells are high efficiency if the carrier mobility and electrical conductivity of the D and A layers are high. However, only the excitons generated near the D/A interface contribute to the photocurrent.
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.
Silicon-based heterojunction solar cells (Si-HJT) are a hot topic within crystalline silicon photovoltaic as it allows for solar cells with record-efficiency energy conversion up to 26.6% (Fig. 1, see also Yoshikawa et al., Nature Energy 2, 2017).
On the back side, an electron collecting stack is used, and it is composed of an intrinsic a-Si:H passivation layer, a doped n-type amorphous silicon (both deposited by PECVD), a TCO layer and a metallic contacting layer (deposited by PVD).

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.
