“…Under high sun-light illumination, the electric field of i-layer weakens and the recombination ratio increases near i/n interface. From our previous theoretical study, we observed that one effective way to improve these phenomena is decreasing thickness of i-layer [7].…”

“…A numerical analysis was carried out using a onedimensional device simulation program AMPS-1D (Analysis of Microelectronic and Photonic Structures) [8] in order to investigate the influence of irradiance intensities of sunlight on multi-junction silicon-based thin-film solar cell performances. The concentration ratios of incident light were varied from 0.01 to 50 suns.…”

Multi-junction silicon-based thin-film concentrator solar cells are promising candidate to achieve both low-cost and high-efficiency. For the application of silicon-based thin film solar cells to concentrator photovoltaics, it is required to be revealed the light intensity dependence of the performance of silicon-based thin film solar cells. From these reasons, in this study both calculation and experimental studies were conducted with several types of single-junction and multi-junction tandem solar cells. From both simulation and measurement results, we observed that double-and triple-junction solar cells achieve high open-circuit voltage and large logarithmic increment in open-circuit voltage with increasing lightintensities. On the other hand, it became clear that the drop of fill factor is required to be improved for the realization of the multi-junction silicon-based thin-film solar cells with very high efficiency under low concentration ratios of sunlight.

“…From these reasons, as a first step of the development for multi-junction silicon-based thin-film concentrator solar cells, we had studied the performance of solar cells under various light intensities. Previously we have performed theoretical analysis and experimental study on the performance of single-junction μc-Si:H solar cells [6,8].…”
