Abstract: The improvement of device performance of a recycling solar air heater featuring a wire mesh packing was investigated experimentally and theoretically. The application of the wire mesh packing and recycle-effect concept to the present study were proposed aiming to strengthen the convective heat-transfer coefficient due to increased turbulence. Comparisons were made among different desi...

Dye-sensitized solar cells (DSCs) promise a short energypayback time and offer a potential lowcost alternative to conventional photovoltaic devices based on semiconductors. This work describes the effort which has mainly been developed on DSSC solar cells with suitable dye for light harvesting and interfacial electron transfer processes with nano crystalline wide band-gap semiconductors. The ph...

Solar-induced ventilation could be provided by incorporating the solar chimney with buildings. This technique is getting popular in new constructions which are intended to exploit renewable resources to save conventional energy without sacrificing indoor thermal comfort and air quality. Authors [1] [2] have been conducted various experimental and theoretical studies on ventilation performance o...

In this paper, a scaling analysis using a simple three-region structure was conducted for the unsteady natural convection boundary layer (NCBL) of a homogeneous Newtonian fluid with Pr > 1 adjacent to a vertical plate evenly heated with a time-dependent sinusoidal temperature. A series of scalings were developed for the thermal boundary thickness, the viscous boundary thicknesses, the maximum v...

UNLABELLED To fabricate high-performance metal-halide perovskite solar cells, a thermal annealing process is indispensable in preparing high quality perovskite film. And usually such annealing is performed on hot plate. However hot-plate annealing could cause problems such as inhomogeneous heating (induced by non-tight contact between the sample and the plate), it is also not fit for large scal...

Seasonal solar thermal energy storage (SSTES) has been investigated widely to solve the mismatch between majority solar thermal energy in summer and majority heating demand in winter. To study the feasibility of SSTES in domestic dwellings in the UK, eight representative cities including Edinburgh, Newcastle, Belfast, Manchester, Birmingham, Cardiff, London and Plymouth have been selected in th...

The demand for low-priced solar cells with higher efficiencies becomes more necessary to reach grid parity. An optimized solar cell design which uses the same equipment as state of the art solar cells could be easily implemented into solar industry. In this paper an approach for a front side design is discussed, using more busbars than the widely used three busbar design for the solar cell fron...
