On the basis of the summarization of the development and research status of quantum structure solar cell, starting from the structural model of quantum structure solar cells, the First principles was used to calculate the limit efficiency, and according to the Shockley-Queisser limit and the principle of detailed balance of a p-i-n junetion, theoreti- cal analysis and calculation for the limit efficiency, optical properties and electrical properties of the InGaN quantum structure solar cell were carried out. When a barrier is 1.73 eV and potential well is 1.12 eV, the battery conversion efficiency is 58.4%. When a barrier is 1.89 eV and potential well is 1.35 eV, the battery conversion efficiency is 58.4%.
