    Abstract: Vacuum-free process has been attracted much attention due to its advantages such as low cost, high throughput, and low temperature processes with roll to roll technique. However, one of issues from the vacuum-free process is its relative low efficiency performance. By employing nanostructure to enhance the capability of the light absorption, we are able to boost the efficiency enhancement, which has been reported in various kinds of PV. In this regard, we demonstrate a template-free, facile way to create large area CuIn(S,Se)2 nanotip arrays from vacuum-free CuInS2 nanocrystals. The CuInS2 nanocrystals are synthesized via a chemical process. After coating of CuInS2 nanocrystals on molybdenum substrate, the samples are followed by a post-selenization treatment to form the CuIn(S,Se)2 phase. By simply utilizing one-step Ar+ bombardment process, CuIn(S,Se)2 nanotip arrays can be formed with controllable lengths and tilting orientations by adjusting sputter time and Ar+ incident angles. The nanotips arrays shows a significance decrease in reflectance at incident light wavelengths from 300 to 1200 nm compared with the pristine CuIn(S,Se)2 thin film sample. XRD and Raman analysis were used to further confirm the chalcopyrite phase of CuInS2 and CuIn(S,Se)2. We believe that our unique approach of creating CuIn(S,Se)2 nanotip arrays, including one-step fast process with free of template and non-vacuum process, can stimulate great attention not only from academic investigations but also industrial side for practical applications.
