6 FAQs about [The effect of silicon wafer thickness on battery short-circuit current]
What is the maximum efficiency of silicon wafers?
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.
Does wafer thickness affect the performance of SHJ solar cells?
In our work, we study the effect of wafer thickness on the performance of SHJ solar cells with a focus on the open-circuit voltage and FF. The potential and losses in experimental SHJ solar cells prepared on wafer with thickness in the range from 60 to 170 μm are investigated.
Does wafer thickness affect temperature coefficient of silicon heterojunction (SHJ) solar cells?
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]
Why do wafer thicknesses decrease VOC?
An alternative explanation is that at such low thicknesses, there is a higher possibility of wafer damage during the metallization process, which may also result in this drop on VOC. [ 42, 43] In predictions by Richter et al., a slight increase in FF with reduced thickness is expected for the studied wafer thickness range. [ 2]
How does wafer thickness affect effective carrier lifetime?
A reduction in wafer thickness leads to reduction of the effective carrier lifetime. The points of 1 sun i FF for all studied solar cell precursors are dominated by surface passivation; thus, reduction of wafer thickness leads to gradual reduction of i FF as opposed to the Auger limit predictions.
Why does a corner cell have a larger short circuit current?
It should be noted that for a large-size PV module, a corner cell will have a larger short circuit current than the middle cells due to the large backsheet area on the edge. In our simulation, we assume all the cell receives the same amount of light from the backsheet and calculate an average value.
