Working Principle: The working of solar cells involves light photons creating electron-hole pairs at the p-n junction, generating a voltage capable of driving a current across a connected load.
A conventional front junction solar cell forms a collecting (p-n) junction near the front surface, at a depth of ∼0.5 μm. Thus, the overall carrier collection efficiency of a front junction solar cell is primarily dictated by the rear surface recombination parameter.
The front side metallization is same for all solar cells. Data shown here corresponds to a set of 10 solar cells for each set of experimental condition. The fill factor of the solar cells improved slightly when the LCO pitch was increased from 100 μm to 250 μm, but deteriorated with further increase in the LCO pitch.

This chapter highlights key areas of innovation and progress in solar cell research.
The current landscape of solar cell technology predominantly revolves around crystalline silicon solar cells, which account for the majority of the market share. Silicon solar cells come in two main forms: monocrystalline and polycrystalline.
By engineering the bandgap properties, photonic crystals can redirect light toward the active layer of the solar cell. Grating Structures: Gratings consist of periodic structures that act as diffraction elements, redirecting light to specific locations within the solar cell for enhanced absorption.
Improving front contacts of n-type solar cells
In this article we describe the work carried out in order to optimize n-type silicon solar cell front contacts by reducing the contact and line resistances. Both front and back contacts were created by screenprinting of a metal paste followed by the contact firing. After firing the front contacts were improved by electrolytic deposition of silver using a non-cyanide silver solution. …
