Light reflection from the glass surface of thin film photovoltaic (PV) modules is a source of significant energy loss for all types of thin film devices. The reflection at the glass and air interface accounts for ∼4% of the total energy. Currently, most of the commercial thin film solar modules are manufactured using a glass superstrate/substrate with no light trapping strategy to reduce the reflection loss. To minimise these losses, a series of broadband multilayer thin film coatings has been designed and tested. Anti-reflection coatings for CdTe, CIGS, perovskite and a-Si thin film PV are presented in this paper. The coatings consist of four to six dielectric layers of alternating thin films of ZrO2 and SiO2. The layers were deposited by using a high deposition rate pulsed DC magnetron sputtering tool. Spectrophotometer measurements confirm that the transmission increased by between 2% and 5% over the spectrum utilized by each thin film solar cells. The weighted average reflection reduced from around 4.22% to 0.62% (a-Si-4 layers), 0.80% (perovskite-4 layer), 1.22% (CdTe-4 layers), and 1.49% (CIGS-6 layers). This results in an increase in current density and cell efficiency. These dielectric coatings are highly durable and scratch resistant.
