High-efficiency nano-structure solar cells

Cost-efficient, high-efficiency solar cells are interesting for all applications where off-grid energy is needed. Combining silicon solar cells and high efficiency solar cells into such a solar cell has been a dream of the solar industry for four decades. But differences in the material properties have rendered it impossible. A handful of research groups and companies are pursuing R&D on this type of solar cell. All of them are however using materials and/or techniques that are incompatible with integration on silicon solar cell substrates, or have a lower maximum efficiency than the materials used by Gasp Solar. Gasp Solar has developed, and patent protected, a significantly better material combination allowing for reaching higher efficiencies at the same cost.Together with DTU CEN, DTU Fotonik, and UCL in London, Gasp Solar will develop this solution to reach an initial efficiency of 20%.
