TL;DR: In this article, a large area was fabricated by a random reactive ion etching (RIE) texturing method using SF 6 /O 2 plasma chemistry, and the best MC-Si solar cells showed conversion efficiency, fill factor, short circuit current density, and open circuit voltages as high as 17.4%, 80%, 35 µm 2 and 620 µmV, respectively.

TL;DR: In this article, a novel approach for optimization of co-firing temperature profile in rapid thermal processing (RTP) is investigated by measuring the actual temperature of front and back surfaces of the solar cell.

TL;DR: In this paper, an optically and electrically optimum front electrode was reported by using a transparent conductive oxide (TCO) film integration, which was achieved by reduction of silver (Ag) grid shading losses while holding a similar series resistance.

TL;DR: In this paper, a transparent conducting oxide (TCO) layer was applied in crystalline Si (c-Si) solar cells without use of the conventional SiN x -coating.

TL;DR: In this article, the negative ion generation on an AZO target was contributed by the surface ionization leading to the spot emission from Al atoms adsorbed on the target surface, and the contribution of negative ions' current was mainly from the erosion area of the target due to its higher temperature.
