Unformatted text preview: e (a-SiN). Crystalline Silicon offers an improved efficiency when compared to amorphous silicon while still using only a small amount of materials. The commercially available multi-crystalline silicon solar cells have efficiency around 14-19%. P HOTOVOLTAIC THERMAL COLLECTORS [ 4 ] Hybrid photovoltaic/thermal (or simply PV/T) collectors are devices that simultaneously convert solar energy into electricity and heat. A PV/T collector typically consists of PV module on a back of which an absorber plate (a heat extraction device) is attached. 22 Figure 17: Photovoltaic Collector17 A number of solar cells electrically connected to each other and mounted in a support structure or frame is known as a photovo...
