However, the complete development of the “modern” SHJ structure took place well before BO defect stabilization processes were developed. Due to the susceptibility of p-type Czochralski (Cz)-grown silicon to BO-LID, such wafers were deemed unsuitable for SHJ solar cells.
If commercial-grade c-Si wafers were used to fabricate SHJ solar cells, the severity of BO-related degradation would impact the conclusions regarding the potential of such wafers of achieving the V OC required by SHJ solar cells, if care was not taken to prevent any unwanted light-exposure prior (and during) solar cell characterization.
Based on these findings, the potential of p-type wafers to enable a next-generation of high-efficiency solar cells featuring carrier-selective contacts is discussed. A silicon heterojunction (SHJ) solar cell is formed by a crystalline silicon (c-Si) wafer sandwiched between two wide bandgap layers, which serve as carrier-selective contacts.
