Optical Design Impact on PERC Solar Cell Efficiency: Upright Pyramids vs Inverted Pyramids Textured Surfaces

Aims: Textured surfaces morphology on solar cell are benefited to minimize the reflection. Many configurations are used for solar cell manufacturing. The ray’s simulators are used in this work. The gains (photogeneration) and losses (reflection, transmission, parasitic absorption) are recorded for each ray. The global gains and losses are determined by averaging many rays. With a sufficiently large number of rays, the Monte Carlo simulation converges to the physical model. The Monte-Carlo algorithm employed by the Wafer Optics Calculator necessarily results in output uncertainties. These uncertainties are calculated by dividing the user-requested number of rays into several sub-simulations, then applying statistical analysis to the set of sub-simulations to arrive at a mean value and 95% confidence interval (about two standard deviations). The calculators weight the magnitudes by the photon flux in the user-defined spectrum, then integrates over the wavelength, to calculate photon current density. The photogenerated current JG in a wafer equates to the short circuit current that could be extracted from a perfect solar cell made from the wafer. This work focuses on two textured surfaces morphology such that, upright pyramids, and inverted pyramids. To show their impact in solar cell efficiency. Which involve evaluating the external reflection for both surface morphology. Also compare the photogeneration JG absorbed by the substrate.
