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

International 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

Graphene-based photovoltaic cells for near-field thermal energy conversion [PDF]

, 2012
Thermophotovoltaic devices are energy-conversion systems generating an electric current from the thermal photons radiated by a hot body. In far field, the efficiency of these systems is limited by the thermodynamic Schockley-Queisser limit corresponding ...

Study on heat transfer process of insulated floating cover of water pit for solar seasonal thermal storage

Energy Reports, 2022
Water pit thermal energy storage (PTES) can transfer the solar energy heating from the non-heating season to the heating season, which can efficaciously cope with the mismatch problems in energy intensity, usage time and space of solar energy heating ...

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

Energy 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.
