Thin-film CIGS manufacturer AQT Solar has announced its completion of a significant phase of its CZTS prototype module development, producing a 60-watt module in collaboration with its manufacturing partners. Earlier this year, the company revealed that it had achieved high efficiencies with its sputter-deposited CZTS thin-film solar cell.

The company claims that its speedy development was enabled by implementation of its “material agnostic production platform”, which has seen the company conduct “under-sun” testing for the past several months.

It is claimed that CZTS solar cells have low manufacturing costs, better energy harvesting than c-Si cells and lower yield losses during module assembly.
