The contact quality of metal-semiconductor (MS) can influence the solar cell''s performance dramatically. 15 Hence it should be investigated carefully to attain the best possible design for a device. While NiO is p-type, the main focus has been on contacts between metals and this type of semiconductor.
One of the concepts is to keep both the contacts on the back side of the solar cell and shift the emitter to the rear side. This type of cell is called an interdigitated back contact (IBC) solar cell, as the contacts are alternately arranged on the rear side with the interdigitated format.
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.
The buried-contact solar cell of Fig. 12 was developed to overcome the efficiency limitations of the screen-printed cell approach. The most distinctive feature of this approach is the use of laser-defined grooves in the top surface to locate the cell metallization.
The standard conventional solar cell has an emitter on the front surface and contacts on both sides of the device. Different concepts have been developed to improve the efficiency of the solar cell to meet higher power ratings.
All solar cells fabricated in this work featured selective poly-Si contacts on the front side. 10 solar cells were fabricated for each individual experimental split/variation presented in this work. The front side of the solar cells incorporated poly-Si fingers over which the metal fingers were screen-printed.
a, Solar cell modelling in which the rear contact parameters (J0c and ρc) act as the input and the optimized contact fraction (black lines fc), and so cell efficiency (coloured contours) is output. The modelling, performed in Quokka 2.0 228, is based on perfect absorption and an idealized front contact.
