- Abstract
Soft lithography refers to a series of fabricating techniques for replicating structures using "elastomeric stamps, molds, and conformable photo masks. In this paper, we have fabricated an array of micro-scale PMMA/SiO2 Fresnel lenses CPV-system for high efficiency crystalline silicon solar cells(Si-Solar cells). Fresnel rings units containing eleven concentric rings having maximum diameter of45.24μm were created on PMMA layer. The resulting CPV-system when placed on the surface of Si-Solar cells increased the open circuit voltageV0C by 17.9mV, short current ISC by 31.22mA and the maximum power Pmax by 11.42mW. Meanwhile, this system enhanced power conversion efficiency of Si-Solar cells by 3.54% and decreased the series resistance Rs of Si-Solar cells by 0.81Ω.
