How to improve Organic solar cells'(OSCs) photoelectric conversion efficiency (PCE) is an urgent problem to be solved. One of the more commonly used methods is to add micro-nano structures for light trapping into the photoactive layer of OSCs to increase light absorption, thereby improving PCE. The photonic crystal (PC) structure is used in the photoactive layer of OSCs, which can enhance the light absorption of solar cells in specific wavelength bands. This case uses FDTD simulation to analyze the light absorption of an OSC with a 2D hexagonal-lattice PC structure.

Solar cell is a device that converts solar energy into electricity. When sunlight irradiates a semiconductor material with photovoltaic effect, electron-hole pairs (photogenerated carriers) are generated. An electric current can be produced by inducing electrodes at both ends of the solar cell. In this example, we simulate a planar silicon solar cell by SimWorks Finite Difference Solutions to calculate the absorption of solar energy (300-1100nm) and further to compute the photon generation rate and the corresponding photocurrent.
