Design and construction of non-imaging planar concentrator for concentrator photovoltaic system

Performance study of crossed compound parabolic concentrator as secondary optics in non-imaging dish concentrator for the application of dense-array concentrator photovoltaic system

“…error ranging from 0°to 0.4°with increment of 0.1°. The choice of range for pointing error takes into consideration of practical tracking accuracy as if a 12-bits optical encoder is employed as feedback sensors in the tracking algorithm (Chong et al, 2009a(Chong et al, , 2009b. After setting all the parameters for primary concentrator, secondary concentrator and receiver planes, the ray-tracing program is initiated to plot the flux distribution pattern on the receiver planes for both NIDC and exit apertures of CCPC lenses.…”

The optical design and performance of a concentrator photovoltaic module

“…Since the I sc is directly proportional to the concentrated incident irradiance, it will increase linearly with concentration (Hegedus. & Luque, 2002;Cotal et al, 2009;Chong & Siaw, 2008). The logarithmic increase observed in the V oc is due the increased in I sc with increasing irradiance (Cotal et al, 2009;Kinsey et al, 2009).…”

“…The secondary element distributes the intensity and spectral content of the concentrated light homogeneously across the area of the CPV receiver (CTJ) as illustrated in Figure1. The increased photon flux on the CTJ results in increased photocurrent density and hence, will lead to an increased power output from the CTJ (Kost et al, 2014;Chong & Siaw, 2008;Rumyantsevm et al, 1997).…”

Waveguide solar concentrator design with spectrally separated light

“…The basic principle of solar concentration is to use a low cost optical component that concentrates sunlight onto photovoltaic (PV) cells (Luque and Andreev, 2007;McConnell and Symko-Davies, 2006;O'Gallagher, 2008;Takamoto et al, 2005;Wurfel, 2005). Three main families of concepts exist in relation to photovoltaic processes: reflective optics (Chong et al, 2009;Coventry, 2005;Cvetković et al, 2007;Feuermann and Gordon, 2001), refractive optics (Leutz, 2000;Vasylyev, 2005;Xiea et al, 2011;FerrerRodrguez et al, 2017;Steiner et al, 2016;Helmers et al, 2013) and light guide techniques (Gallagher et al, 2007;Goldschmidt et al, 2009a;Goldschmidt et al, 2009b;Karp et al, 2010).…”
