In any case, various carrier-selective layer options for efficiencies > 26% exist and many more are currently developed in the PV labs world-wide. Transferring these new concepts to industrial solar cell production will be the next major challenge. Funding was provided by the State of Lower Saxony. Sol. Energy Mater. Sol.
The transparent conductive oxide (TCO) at the cell rear can improve the rear reflectance and is optional, whereas the front TCO in the case of the both-sides-contacted cell shown in (a) is required to provide the lateral carrier transport to the front grid fingers. 2. Present status of surface passivation in industrial solar cells
Contacting a solar cell requires a metal/semiconductor interface that typically shows strong recombination. For this reason it is advantageous to cover only a few percent of the cells front and rear side area with a metal.
Only very recently, a solar cell with an efficiency of 20.0% has been reported on n -type silicon with a thermally evaporated MgO x /Al electron-selective contact at the cell rear .
We would like to mention here that the unmetallized solar cell precursors exhibited an implied V oc (i V oc) of ≈720 mV after patterning and before laser processing. The LCO metallization approach results in a loss of ≈25 mV. Most of our ongoing efforts and those in near are towards minimizing the V oc loss. Fig. 13.
However, solar cells incorporating poly-Si based passivating contacts both on front and rear of a solar cells could have the potential to achieve efficiencies exceeding 26% [15, 16]. There has been increased interest in the solar cells with passivated contacts on both front and rear side.
