These parameters are correlated to the performance of the emitter (collection efficiency [ IQE0] and width [ we ]), bulk region (surface recombination velocity [ SRVB] and effective diffusion length [ Leff ]), and rear optics (rear internal reflectance [ RB] and how diffused the light is after internal reflection [ DB ]) of a Si solar cell.
The power conversion efficiency of a solar cell is a parameter that quantifies the proportion of incident power converted into electricity. The Shockley-Queisser (SQ) model sets an upper limit on the conversion efficiency for a single-gap cell.
The prospects of various solar cell technologies are promising but differ in focus. Silicon-based solar cells continue to evolve, with prospects for improved efficiency and cost reduction through advanced materials and manufacturing techniques.
In 2022, a perovskite cell was fabricated based on Cs 0.05 FA 0.95 PbI 3 composition (of 1 cm 2) by using vacuum evaporation and the efficiency obtained was 23.44% for 1 cm 2 aperture area (Hoppe and Sariciftci, 2004). In Fig. 6a. the schematic structure of a typical Planar Perovskite Solar Cell is provided. Fig. 6.
A similar methodology was proposed by Abdullah-Vetter et al. [ 49] to automate the analysis of internal quantum efficiency (IQE) measurements. IQE curves of Si solar cells were simulated using an analytical model [ 50] and a series of RF models were trained to predict six key parameters from the curves.
These cells are more effective because they employ a variety of absorber materials with different bandgaps, allowing them to effectively absorb a wider range of sunlight wavelengths and so enhance both spectrum utilization and overall efficiency.
