MiaSole Commercial Scale Thin-Film Solar Modules Reach 13.8 Percent Efficiency

Miasole reports that that the U.S. Department of Energy’s National Renewable Energy Laboratory (NREL) independently confirmed the 13.8 percent efficiency of its copper indium gallium diselenide large area production modules (one square meter in size). The modules are designed for utilities and independent power producers in industrial scale deployments such as large-scale rooftop and ground mount installations. Miasole asserts that the new high efficiency will allow it to offer solar modules with the efficiency of polysilicon and the lower manufacturing costs of thin-film modules.

The company utilizes a unique manufacturing process which lays CIGS on a flexible stainless steel substrate in a continuous sputtering process.
