Effect of temperature in electrochemical texturising of multi–crystalline silicon in KOH solution
In this paper we present the study of electrochemical etching of silicon in KOH solutions to improve texturisation and reflection properties of p–type multi–crystalline silicon. The influence of etching temperature on surface morphology and reflection properties of the silicon wafers has been investigated. The results of the study showed that etching at high temperatures formed isotropic textured ...

Applicability of Equivalent Diode Models to Modeling Various Thin-Film Photovoltaic (PV) Modules in a Wide Range of Temperature and Irrandiance Conditions
Abstract In the paper results of fitting of current-voltage (I-V) curves acquired in a wide range of irradiances and temperatures with use of equivalent either single (SEM) or double (DEM) diode model as applied to several commercial thin-film photovoltaic (PV) modules are presented. It is shown that like in case of crystalline silicon PV modules also for CIGS (CuInGaSe2) as well as CdTe ...

Comparison of the Temperature Coefficients of the Basic I-V Parameters for Various Types of Solar Cells
Abstract It is well-known that the maximum power output of photovoltaic devices changes with temperature. Therefore, the temperature coefficients of the basic device performance parameters (open-circuit voltage, short-circuit current, fill factor, and efficiency) are important factors which must be taken into account in the design of a photovoltaic power system, where temperature changes occur ...

Where Are We Now? A Brief Overview of the Current Solar Industry
Although there have been reports of a decline in renewable energy investment over the past few years, the outlook for the current solar industry has been improving. In 2012, a total of 31 gigawatts of solar capacity was installed, while 39 gigawatts of capacity was installed in 2013 even though overall investment in solar energies fell by 23 percent between the two years. According to the ...

Solar Cell Thin Film Analysers: The Basics
Global energy consumption is rapidly outstripping the available supply. When we factor in that over half of the world’s electricity is generated by non-renewables and that the global population growth remains incredibly high, concerns about the energy sector’s ability to provide for future generations seem well-founded. A gradual pivot towards renewables seems both inevitable and ...

A primogenius study on characterisation of c-Si solar cell
The use of solar photovoltaic (PV) as distributed energy resources is increasingly being pursued as a supplement and alternative to conventional grid electricity. It has become an important source of energy because of its high reliability, requirement of very little maintenance and capability of generating power with no noise and emissions. Silicon solar cell as renewable energy resource has ...
