“…The unwillingness of relatively poor households to adopt solar home systems highlights the energy access gap that financial constraints engender. Our findings are similar to those of Billino ( 2009), Ugulu (2019) and Qu et al (2019) who found that household income levels propel the willingness to adopt solar home systems (SHSs). This phenomenon calls for probes by all relevant stakeholders to consider ways through which SHSs can be made affordable irrespective of socio-economic status.…”

Ghana heavily relies on hydrogenated and thermal electricity. For the past thirteen years, the dynamics of climate change and increasing fuel prices have engendered an electricity crisis since the supply of electricity cannot match the ever-burgeoning demand from households and industries. While this is so, the uptake of renewable energy sources has been abysmal in Ghana. This study thus seeks to assess the adoption behaviour of solar home systems, an environmentally friendly and convenient alternative electricity source by households in Ashongman Estate, a suburb of Accra, Ghana. Using a mixed research approach including binary logistic regression analysis, the study found that education, income levels, the performance expectation and housing tenure arrangements were crucial factors that determine the willingness of households to adopt the solar energy sources. We recommend that to encourage the uptake of Solar Home Systems (SHSs) which are environmentally sustainable, it is expedient that government collaborates with relevant stakeholders to provide solar home systems (SHSs)for households with the necessary technical capacity while putting financial policy measures in place to ensure their affordability regardless of socio-economic status. In addition, we recommend further studies to explore the role of incentives in solar home systems adoption to inform policies that will encourage their uptake.

“…[7,8,9,10] Advanced photothermal conversion devices can utilize the solar energy effectively, [11,12,13,14] but the photoelectric conversion efficiency still needs to be improved. Louise et.al [15] clarified the intrinsic loss mechanism that lead to fundamental limits in solar cell efficiency. Their valuable study [15] indicated that the photons with energy below the bandgap restricted the current of PV cell.…”

“…Louise et.al [15] clarified the intrinsic loss mechanism that lead to fundamental limits in solar cell efficiency. Their valuable study [15] indicated that the photons with energy below the bandgap restricted the current of PV cell. There is an increasing concern that photoelectric conversion cannot convert the full solar energy spectrum (400~2 500 nm) into electricity due to the mismatch between the band gap of the semiconductor material and the broad range of solar photon energies.…”

Conventional Si photovoltaic cells cannot convert full solar energy spectrum (400~2 500 nm) into electricity owing to the mismatch between Si band gap and broad range of solar photon energies. Transparent silicon PV cell allows sunlight in the wavelength of 1 100~2 500 nm to transmit through itself and irradiate on the thermal absorber below. The traditional photon management method based on texturing silicon layer with nanostructures can enhance 400~1 100 nm absorptivity and 1 1002 500 nm transmittance of transparent silicon PV cell. However, an increase in charge carrier capture and a decrease in electricity generation efficiency are often observed with this. In this study, a novel spectral splitting method based on frontlocated wavelength-sized TiO 2 biomimetic moth-eye nanophotonic structure is put forward, which can inhibit the increase of charge carrier capture and recombination. The biomimetic moth-eye nanophotonic structure was optimized by using finitedifference time-domain (FDTD) method to achieve excellent photon anti-reflection and scattering properties. The calculation results indicated that the absorption factor and transmission factor of transparent silicon PV cell could be increased from 46% to 58% and from 11% to 14%; the relative power conversion efficiency enhancement rate and relative incident radiation power enhancement rate was 32% and 27% when the TiO 2 biomimetic moth-eye was adopted.

In this paper, we studied in particular solar energy that recovers heat from solar radiation in a fluid, by converting the solar energy into thermal energy by the implementation of thermal solar collectors. This study is the modeling of heat transfer of the parabolic solar collector trough. The objective of this recent simulation is to determine the variation of the outlet temperature, the useful energy and the thermal efficiency of two different receivers. The fluid is water liquid. In order to determine these parameters, we simulate the different types of receivers by the MATLAB/Simulink. According to the simulation findings, using the second receiver leads to an increase of the fluid temperature at the output and the overall solar collector thermal efficiency.
