Failure Analysis of CIGS Solar Cells by SEM/EDS

Explanation of Light/Dark Superposition Failure in CIGS Solar Cells

CIGS solar cells in many cases show a failure of light/dark superposition of their currentvoltage (J-V) curves. Such failure generally becomes more pronounced at lower temperatures. J-V measurements under red light may also show an additional distortion, known historically as the “red kink”. The proposed explanation is that a secondary barrier results from the conduction band offset between CIG...

Numerical Simulation of CdS/CIGS Tandem Multi-Junction Solar Cells with AMPS-1D

Numerical modeling of polycrystalline thin-film solar cell serves as an imperative procedure to test the suitability of proposed physical clarification and to anticipate the effect of physical changes on cell performance. All in all, this must be conducted with only partial knowledge of input parameters. In this paper, we evaluated the numerical simulation of CdS/CIGS tandem multi junction sola...

Recycling of CIGS solar cell waste materials

The increased interest in solar power over the last few decades has led to a constant development of existing and new types of solar cells. One type of solar cell that is making advances on the global market is copper indium gallium diselenide (CIGS) thin film solar cells. The advantage of thin film solar cells is that they require less semiconductor material than conventional silicon solar cel...
