The use of the scribing method for the carbon perovskite solar modules

What is it about?

in order to optimise the geometric fill factor, the scribing method was used for the fully printable perovskite solar cells. However, to minimise the waste of space, the contact area should be minimised. Porous carbon electrodes, however, are not as conductive as compact metal electrodes. This study shows the effect of the contact area and the distance between the cells

Why is it important?

The fully printable carbon perovskite solar cells are most likely to achieve market penetration in the near future. This because of the low-capital cost, the unexpensive materials and process that is adopted, and the long term stability that this perovskite solar cell architecture can achieve. To obtain large area devices with high output power, the coverage of the substrate with active areas is crucial. This work adopts the scribing method to achieve high output power per substrate area. The issues that can be faced with the use of this method were presented and overcome.
