SHJ modules are estimated to be approximately 3-4 ¢/Wp more expensive than PERC modules (both assuming Chinese manufacturing; sources cite 2018 benchmark). The majority of the increased operational expenditure is due to differences in metallisation technology, which was estimated to be responsible for about 1.8 ¢/Wp of that difference. The cost of PECVD for a-Si and sputtering for TCO layers were also significant contributors to cost increases. Other factors include higher cost of n-type
