As the scale of the solar cell moves into nanometer regime, the numerical analysis should evolve at the same pace. By using the Matlab (R) as the tool and solving the general Poisson and continuity equations, we are able to have a good platform for the nano-scale solar cells. By adapting proper parameters, the perovskite solar cells and their behavior under different surface recombination conditions were analyzed.

In this work, we demonstrate the influence of the substrate thickness and the arrangement of nano-rod arrays on the n-side up GaAs thin film solar cell. The J-V characteristics can be altered significantly with different design parameters. The thickness of the substrate can have strong influence on the collected carrier. Also the closeness of the rod to each other can affect the short-circuit current as well due to the limited penetration depth of the photons.
Numerical Study on Doping and Positioning Effect of Type-II GaSb/GaAs Quantum Ring Layer on Solar Cell Performances

In this work, we demonstrate the doping concentration and positioning effect of the type-II quantum well (QR) on the solar cell performances in terms of numerical simulation. The variation in doping concentration and location can affect the band diagram seriously and possibly form the back surface field which can either facilitate or deteriorate the carrier collection. A wide range of parameters are calculated to reveal this trend and the previous experimental results are also discussed.
