We developed a novel process for synthesizing Si solar cells with improved efficiencies. The process involved the formation of pyramid-like structures on the Si substrate and the deposition and subsequent thermal annealing of an antireflection coatin

We have developed a new texturing method by forming a pyramidal black silicon structure using a metal mesh in the reactive ion etching (RIE) system in order to overcome the disadvantages of the texturing process using wet etching and the drawbacks of

We have developed a surface texturing process using a polytetrafluoroethylene coating with a pyramidal structure for obtaining superhydrophobic surfaces. In order to investigate the hydrophobic properties of the surface, we measured the contact angle

We have found optimized RIE conditions by increasing the distance between the metal mesh and silicon wafer. We have also found that by increasing the reactive ion etching (RIE) process time with an optimized SF 6 /O 2 ratio, pressure, and RF power. I
