US technology developer Solar3D has begun fabrication of a manufacturing prototype of a crystalline silicon (CSi) cell it reckons could reach game-changing efficiencies of better than 25% by using micro-PV technology and light-management techniques from the fibre-optics industry.

Solar3D’s maiden prototype, which uses a three-dimensional design to trap sunlight inside a PV structure where photons “bounce around” until converted into electrons, produced 250% of the power of a conventional CSi cell made under the same conditions.

“When we completed our first prototype...we achieved more power, relative to current technology, than we dared to hope. As we continue our work, we have discovered a number of ways to fine-tune our process so the product will produce even more power, and be less expensive to manufacture,” says director of technology Changwan Son
