The highest efficiency thin-film polycrystalline CuIn1−xGaxSe2 (CIGS) and CdTe solar cells are compared directly with crystalline Si and GaAs cells with similar respective bandgaps. The excess efficiency losses (6.3% for CIGS and 9.9% for CdTe) are

The current–voltage curves of many ZnO/CdS/CuInSe 2 solar cells display significant distortion when only red light illumination is employed. This distortion generally disappears or partially disappears for a period of time following illumination wi

Solar cells suitable for the space environment must combine high-efficiency, high energy density, and radiation hardness in a manufacturable design. As improvement in one performance parameter usually results in degradation in one or more of the rema

Extensive environmental testing is necessary to assess the ability of thin-film solar cells to survive launch and space operational conditions. Such testing is vital prior to the use of thin-film solar cells in space and the realization of their bene

In 1999 Spectrolab completed design and qualification, and began production on the next generation of multijunction solar cells-a triple-junction GaInP/GaAs/Ge. With over 20% AM0 conversion efficiency at an operating temperature of 60/spl deg/C, this

A significant photocurrent loss in CdS/CdTe solar cells is due to window-layer CdS bandgap absorption below 520 nm. This work evaluates a coordinated effort by six laboratories to optimize the CdS thickness to increase CdTe cell performance, Quantum
