Honda Soltec to Release New Enhanced Thin-film Solar Cell in 2011

January 26, 2011 - Honda Soltec Co., Ltd. will this year release a new thin-film solar cell with an even more compact design than the current model to allow efficient installation on a wide range of roof shapes. The module conversion efficiency*1 of the new solar cell module is expected to exceed 13.0%, ranking it among the world’s most efficient CIGS-based thin-film solar cells*2.

Based on the following formula to calculate the efficiency of converting solar energy striking 1m2 of module surface into electricity:
Module nominal maximum output (W) × 100
Module area (m2) × 1000W/m2
Solar cells consisting of a thin film made from a compound of copper, indium, gallium and selenium (CIGS)

[Key Features of the New Solar Cell]

  • The performance of the photosensitive CIGS layer has been improved and the surface area of the surrounding frame and other non-photosensitive portions reduced, resulting in approx. 10% increase in module conversion efficiency compared to the current model. This results in more power generated from the same installed surface area.
  • The new model is more compact, with only approx. two-third the module surface area of the current model, allowing it to be installed in limited space on a wide range of roof shapes. This will facilitate the efficient installation of more thin-film solar cells in a variety of locations.

The prototype manufactured using existing Honda Soltec equipment achieved a module conversion efficiency of 13.0%. Honda is working to further improve module conversion efficiency as it brings the product to market.

Honda's independently developed CIGS thin-film solar cells require little energy in the manufacturing process, further contributing to environmental preservation. Honda will continue to contribute to the preservation of the global environment by developing thin-film solar cells that respond to market needs, thereby promoting further widespread use.

These figures were measured by Honda under the conditions of AM1.5, solar radiation intensity of 1kW/m2, and module temperature of 25 degrees Celsius.
Actual output will differ depending on solar radiation intensity, installation conditions (direction, angle, surrounding environment), geographical area, and temperature conditions.
Prototype specifications may be different from the final product.
