This document discusses transparent solar cells that use a molecular organic donor chloroaluminum phthalocyanine and a molecular acceptor C60 to harvest energy. These solar cells achieved a power conversion efficiency of 2.4% +/- 0.2%, which is calculated based on the short circuit current, open circuit voltage, and fill factor. While current efficiencies are low at 2-3%, the document predicts efficiencies could reach 15-24% for transparent solar cells and 12-14% for existing solar cell architectures. The conclusion is that sole reliance on individual architectures will not meet energy demands, and greater efficiency is still needed.
