Heterojunction technology is currently a hot topic actively discussed in the silicon PV community. Hevel recently became one of the first companies to adopt its old micromorph module line for manufacturing high-efficiency silicon heterojunction (SHJ) solar cells and modules.
Silicon heterojunction devices rely on the use of thin‐film silicon coatings on either side of the wafer to provide surface passivation and charge carrier‐selectivity. Beyond traditional indium tin oxide, multiple higher‐mobility indium‐based transparent conductive oxides have been employed successfully in HJT cells.
As a result, the open-circuit voltage (V oc) of SHJ cells has recently reached values as high as 750mV. Up to now, only monocrystalline CZ wafers have been used for large-scale manufacturing of SHJ solar cells. The electronic properties of monocrystalline silicon wafers for high-efficiency solar cells are determined by impurities and Figure 1.
The interconnection of SHJ cells is a stumbling block for the whole process chain: soldering, which is used for the interconnection of conventional c-Si cells, is not compatible with LTC Ag paste, which has to be applied instead of the standard fire-through silver paste because of temperature restrictions for the a-Si/c-Si heterojunction.
