Calculation of the cell temperature of a high concentrator photovoltaic (HCPV) module: A study and comparison of different methods

Comparison of methods for estimating the solar cell temperature and their influence in the calculation of the electrical parameters in a HCPV module

“…In this section the V oc -I sc method based on electrical parameters, the thermal resistance method based on the heat-sink temperature and the lineal method based on atmospheric parameters are described [3].…”

“…In order to address this issue, different authors have proposed a range of methods for obtaining the cell temperature. These methods can be classified in three categories: methods based on heatsink temperature, methods based on electrical parameters and methods based on atmospheric parameters [3].…”

Electrical-optical characterization of multijunction solar cells under 2000X concentration

“…A correct estimation of T C is essential to evaluate the real efficiency of the HCPV system. It can be provided by the analysis of V OC , the thermal-resistance and photo-luminescence peaks [6][7]. In any case, an unwanted increase of T C due to the overheating of the materials reduces V OC and causes, therefore, a cell efficiency drop.…”

Scalable solar thermoelectrics and photovoltaics (SUNTRAP)

“…Concentrator photovoltaics (CPV) use lenses or mirrors to concentrate sunlight to increase the incident photon density onto a small area of a semiconductor photovoltaic (PV) cell, typically 30-100mm 2 . There are two main benefits to using CPV, the cost of modules is reduced by exploiting cheap optics which reflect / refract photons onto the receiver assemblies.…”

“…Previous work has shown that cell temperature has a linear dependence on geometric concentration [1]. Several approaches for cell cooling have been investigated for CPV applications to reduce operational temperature below 80 o C [2]. Heat sinks are widely utilised in CPV.…”
