Sharp Provides Highest Full Size Efficiency

Sharp Corporation has achieved the world’s highest full size conversion efficiency of 25.09%*2 using a 6-inch-size silicon solar cell.

This achievement of high conversion efficiency for mono-crystalline silicon solar cell was realized with Heterojunction Back Contact structure, a fusion of back contact structure*3, utilized in Sharp’s high-efficient solar module BLACKSOLAR and heterojunction structure, forming an amorphous silicon film on the surface of mono-crystalline silicon substrate.

This technology accomplishment is supported by the research and development initiative promoted by New Energy and Industrial Technology Development Organization (NEDO)*4 under the theme of “Development of Cost Reduction Technology of High Performance, High Reliability Solar Power Generation”. Measurement of the value of 25.09% was validated by the Japan Electrical safety & Environment Technology laboratories (JET) *5.

Sharp will continue to work to achieve higher conversion efficiency as well as improving power generating costs in order to contribute to the development of renewable energy.
