Abstract :
Recent results from the recrystallization of a silicon sheet by a molten zone optical processing technique are reported. The apparatus has been used with promising results in Silso wafers (as a test material) and in preribbons produced by plasma gun deposition and electron beam processing. The use of the apparatus for obtaining thin ribbons (<200 μm) starting from ordinary preribbons (~0.5 mm) has been demonstrated. This process, called STTRECH, may lead to an important reduction in solar cell cost
