The illuminated side of some types of solar cells, thin films, have a transparent conducting film to allow light to enter into the active material and to collect the generated charge carriers. Typically, films with high transmittance and high electrical conductance such as indium tin oxide, conducting polymers or conducting nanowire networks are used for the purpose. There is a trade-off between high transmittance
PV conversion efficiency measures the percentage of solar energy converted to electricity. 7 While most available solar panels achieve ~20% efficiency, 8 researchers have developed modules approaching
