T he Korea Institute of Energy Research has successfully developed ultra-lightweight flexible perovskite/CIGS tandem solar cells and achieved a power conversion efficiency of 23.64%, which is the ...

South Korean researchers have fabricated a copper indium gallium selenide (CIGS) solar cell with a 90 μm-thick UTG provided by South Korea’s Unique Technology Integral. The device uses a ...

The scientists introduced the cell technology in “Perovskite-CIGS Monolithic Tandem Solar Cells with 29.7% Efficiency: A Numerical Study,” which was recently published in Energy Fuels.

Chinese researchers have achieved a key breakthrough in the development of flexible solar cells. These scientists have developed an ingenious technique to overcome a major obstacle: the roughness of ...

Second Generation: Thin-Film Solar Cells Second-generation solar cells include thin-film technologies such as cadmium telluride (CdTe) and copper indium gallium selenide (CIGS). These cells are more ...

Quantum-dot-based solar cells promise to deliver efficiencies approaching those of crystalline solar cells but with the manufacturing simplicity of organics. Crystalline materials such as silicon ...

This is a microscopic cross-section of a tandem solar cell made with two photovoltaic materials, perovskite and copper indium gallium diselenide, or CIGS. Photographs, videos and other images ...

For high efficiency of such tandem device, the bandgap of the bottom CIGS cell should be ~ 1.1-eV with an anticipated bandgap of the Perovskite cell of 1.6-1.7 eV. In our research group Solar ...
