Solar cell efficiency is the measure of how much incident sunlight is converted into electricity. Most solar cells today are made from silicon, an inexpensive and abundant raw material. Due to the physics of silicon, the theoretical maximum efficiency of high-grade crystalline silicon solar cells is approximately 29%. In commercial practice, the efficiency ranges from 15% to 19%.(1) Our 3D solar cell is calculated to have an internal efficiency of 25.47%, more than any existing silicon solar cell, and is designed to take advantage of low cost manufacturing processes.
