To our knowledge, it is the first experimental demonstration of the dependence of SHJ solar cell performance on wafer thickness in the 60–130 μm range. We demonstrate that the gettering process continues to be beneficial for achieving solar cell efficiency above 26%.
In this study, the impact of wafer thickness on the optical and electrical properties of c-Si solar cells is characterized systematically in a wide range of wafer thicknesses from 400 down to 30 µm, with particular interest in SHJ solar cells. 2. Experimental methods
Theoretical predictions have estimated a maximum efficiency for silicon wafers to be at about 100−110 μm thickness. The potential and losses in silicon heterojunction solar cells prepared on wafers with thickness in the range of 60−170 μm with focus on open-circuit voltage ( VOC) and fill factor (FF) are studied experimentally.
It has been demonstrated that reduction in wafer thickness is beneficial for the temperature coefficient of silicon heterojunction (SHJ) solar cells. [ 14] Departing from the standard 1 sun illumination, once indoor applications are addressed, it is predicted that significant reduction of thickness is beneficial. [ 15]
The SHJ technology inherently possesses an advantage in the production of solar cells on thin wafers, owing to its capability for low-temperature processing. We manufactured solar cells on commercial-size p-type CZ wafers across a range of thicknesses and investigated the relationship between wafer thickness and cell performance.
