The absorber layer is the heart of the solar cell configuration . The optical and electrical properties of I-III-VI2 compound films have majorly relied on their defective chemistry and structure and stoichiometric composition, which are, consequently, majorly associated with firm growth indicators.
When the processing temperature during the deposition of the layers is low, a wide range of low-cost substrates such as glass sheet, metal or polymer foil can be used. The first successful solar cell was made from c-Si and c-Si is still the most widely used PV material.
Due to this, the absorber layers of all thin film solar cells are selected from semiconducting materials with bandgap energies that coincide with the photon-rich region of the solar spectrum.
Solar cell layers technology has achieved global standing in the solar cell layers deposition process, and it covers the innovative methods and techniques in significant applications.
These devices are characteristically developed on polycrystalline absorber layers with thicknesses in the 1–10 range. I-III-VI2 and CdTe ternary and multi-notaries are amongst the polycrystalline compounds formed as absorber layers for the thin-film of high-efficiency solar panels.
Chapter 3. In most of today solar cells the absorption of photons, which results in the generation of the charge carriers, and the subsequent separation of the photo-generated charge carriers take place in semiconductor materials. Therefore, the semiconductor layers are the most important parts of a solar cell; they form the hart of the solar cell.
