Overview: This paper discusses the influence of wafer thickness and surface texturing of silicon solar cells on cell results which has been investigated using neighboring multi-crystalline silicon wafers with thickness ranging from 150 ?m to 350 ?m and isotropic NaOH or acid etched. It was found experimentally that Voc decreases nearly 1.5 % and Jsc decreases nearly 3 %, resulting in a 4 % relative decrease in efficiency, in halving the wafer thickness. These trends are independent of the front surface texturing.
