Abstract

Recently, the important issues of photovoltaic cell are low cost and high efficiency. Making low cost and high efficiency photovoltaic cell, there are many effects to development of inexpensive wafer, simplify process and improve optical, electrical properties [1]. In this the study, the 2 step texturing method using micro blaster was developed to decrease reflection of incident lights. Bridge type electrode structures are suggested to expand the effective surface area and decrease the series resistance of finger electrode. We decided to use 10 μm size powders since efficiency of solar cell could rather reduce by using 50 μm size powders because of their extremely rough surface. And surface of after micro blaster etching with chemical etching method using HNA(HF: HNO₃: CH₃COOH = 4:9:7) solution, dry etching method using RIE, and oxide etching method removes oxide after wet oxidation process.
