Efficiency Enhancement of Nanoporous Silicon/Polycrystalline-Silicon Solar Cells by Application of Trenched Electrodes

Table 1

Parameters of current-voltage characteristics of NPS/poly-Si cells with and without TEC structures. The devices were measured by a solar simulator under irradiation of = 100 mW/cm² at AM1.5, with an irradiated area of 0.5 cm².

Devices	(mA)	(V)	FF	%
Non-TEC Cell	2.42	0.41	0.26	0.52
TEC cell	11.77	0.48	0.36	4.10
