Solar3D’s 3-dimensional solar cell technology has reached a new milestone. The company revealed that it has reached design completion for its light collector element, which should allow the research and development team to begin calculating the efficiency that the 3D solar cell can achieve.
“Our innovative solar cell design has two main sections: a light collector section coupled with a micro-photovoltaic section. The completion of the light collector design is the key to expediting the entire project,” commented Jim Nelson, president and CEO of Solar3D.“The structure of every other element of the cell is dictated by the light collector and flows from its design. While the design element is complete now, we expect minor modifications to further fabricate a prototype.”
Solar3D’s technology uses a 3-dimensional design that is said to trap sunlight inside micro-photovoltaic structures where photons bounce around until they are transformed into electrons. The company was motivated to create 3D solar cell technology after studying the use of light management in fiber optic devices.
“The light collector was the first giant step. We will now be able to know how much of the light will come through to the absorbing structure,” continued Nelson “With that understanding, we will soon know what the increase in efficiency will be with our new cell relative to current technology.”
With this new advancement, Solar3D expects to complete a working prototype by the end of the year.
