copper indium gallium selenide solar cell

CIGS solar cell using aluminum doped zinc oxide film achieves 9.53% efficiency

Scientists have developed a technique for producing AZO and i-ZnO/AZO bilayer structures in solar cells that greatly improves cell efficiency and durability. Using a low power deposition method that avoids raising the substrate temperature, the team achieved a power conversion efficiency of 9.53% with good transmittance.

CIGS module manufacturer announces switch to perovskite

US-based Ascent Solar said its factory for copper indium gallium selenide (CIGS) thin-film PV modules is now dedicated to the industrial commercialization of its perovskite solar tech, which is reportedly showing lab efficiencies above 20%.

Only5mins! – Thin-film solar researcher discusses future of CIGS

The future outlook for copper indium gallium selenide (CIGS) solar cells is bright, due to recent R&D achievements and efficiency gains, according to Ayodhya Tiwari, head of laboratory at Switzerland’s Federal Laboratories for Materials Science and Technology (EMPA). CIGS has already shown its value in building-integrated PV applications, but as production volumes increase in the years ahead, ground-mount plants and big utility-scale installations could also become feasible, says Tiwari.

Swiss scientists achieve 21.4% efficiency for flexible CIGS solar cell

The result was confirmed by Germany’s Fraunhofer Institute for Solar Energy Systems (Fraunhofer ISE). The cell was fabricated through a low-temperature co-evaporation method for the growth of the light-absorbing CIGS semiconductor thin film.

Indium supply not an issue for CIGS industry

Scientists Ayodhya Tiwari and Daniel Lincot recently spoke to pv magazine about the future of copper indium gallium selenide solar tech, which could play a key role in providing flexible, lightweight products in the building-integrated PV segment.
