Realization of Colored Multicrystalline Silicon Solar Cells with SiO2/SiNx:H Double Layer Antireflection Coatings

open access: yesInternational Journal of Photoenergy, 2013
We presented a method to use SiO2/SiNx:H double layer antireflection coatings (DARC) on acid textures to fabricate colored multicrystalline silicon (mc-Si) solar cells. Firstly, we modeled the perceived colors and short-circuit current density (Jsc) as a

Calibration of a single‐diode performance model without a short‐circuit temperature coefficient

open access: yesEnergy Science & Engineering, 2018
We calibrate the seven parameters of a single‐diode model (SDM) for photovoltaic device performance using current‐voltage (I‐V) curves measured under controlled laboratory conditions over a matrix of nominal temperature and irradiance combinations.
