Heat transfer process and fluid flow in a solar chimney used for natural ventilation are investigated numerically the present work. Solar was tested by selecting different positions of absorber namely: at back side, front middle air gap. CFD analysis based on finite volume method is to predict thermal performance, two dimensional under unsteady state condition, identify effect parameters such a...

Thick wafer-silicon is the dominant solar cell technology. It is of great interest to develop ultra-thin solar cells that can reduce materials usage, but still achieve acceptable performance and high solar absorption. Accordingly, we developed a highly absorbing ultra-thin crystalline Si based solar cell architecture using periodically patterned front and rear dielectric nanocone arrays which p...

The non-toxic and wide bandgap material TiO2 is explored as an n-type buffer layer on p-type Cu(In,Ga)Se2 (CIGS) absorber layer for thin film solar cells. The amorphous TiO2 thin film deposited by atomic layer deposition process at low temperatures shows conformal coverage on the CIGS absorber layer. Solar cells from non-vacuum deposited CIGS absorbers with TiO2 buffer layer result in a high sh...

Organic Solar Cells (OSCs) have a great potential for solar energy harvesting due to their low material cost and cheap production. The most common and promising type of OSC is the bulk-heterojunction (BHJ) OSC, which have shown power-conversion efficiencies of 8-10% [1]. The absorber layer in these OSCs consists of a mix of two phases; (i) a polymer, that serves as an electron donor, and (ii) a...

Recent developments in the following areas are briefly reviewed: a) the electrical structure of grain boundaries in CdTe absorbers, b) impurities and non-stoichiometry in CdTe solar cells and c) use of Sb2Te3 in contacts to CdTe. Nominally identical solar cells fabricated using 99.999% pure CdTe feedstock from two different suppliers were compared. Differences in the photovoltaic response and a...

In recent years, perovskite solar cells have been considerably developed, however the lead in the absorber MAPbI3 is a potential threat to the environment. To explore potential alternatives, the structural and electronic properties of MAGeX3 (X = Cl, Br, I) were investigated using different density functional theory methods, including GGA-PBE, PBE-SOC, HSE06 and HSE-SOC. The results implied tha...
