For the bottleneck problem of the conversion efficiency in silicon-based solar cell, the Metallization Wrap– through (MWT) technology is one of the effective methods based on the analysis of factors affecting the solar cell conversion efficiency. The MWT technology is based on laser perforation and that the bus grid lines in the front surface of the solar cell are moved to the back surface. The...

The technology behind a large area array of flexible solar cells with a unique design and semitransparent blue appearance is presented. These modules are implemented in a solar tree installation at the German pavilion in the EXPO2015 in Milan/IT. The modules show power conversion efficiencies of 4.5% and are produced exclusively using standard printing techniques for large-scale production.

UNLABELLED The reflectance of the controlled periodic Si nanowire (NW) arrays is systematically explored, which characterizes the influence on the solar energy harnessing ability by the geometries of the NW. A unique dependence of the reflectance of the Si NW array on the diameter, the height, and the bending of the NW are disclosed. The solar energy loss caused by the reflection of the Si NW a...

Electricity generation using solar photovoltaic systems pose a unique challenge to improve the efficiency and to minimise the manufacturing cost. Research and development in this area has been expanding as it is environmentally friendly and helps the planet to reduce the greenhouse gas emission while reducing the carbon footprint. As a result, solar photovoltaic (PV) electrical power generation...

This paper provides new test methods and analytical procedures for characterizing the electrical performance of photovoltaic modules and arrays. The methods use outdoor measurements to provide performance parameters both at standard reporting conditions and for all operating conditions encountered by typical photovoltaic systems. Improvements over previously used test methods are identified, an...

A solar cell array is inherently a nonlinear device consisting of several solar cell modules connected in series-parallel combinations to provide the desired DC voltage and current. At a fixed insolation level, the terminal voltage decreases nonlinearly as the load current increases. Due to this nonlinearity, it is difficult to determine analytically the operating point at which the output powe...

In the future, solar energy will be a very important energy source. Several studies suppose that more than 45% of the energy in the world will be generated by photovoltaic array. Therefore it is necessary to concentrate our forces to reduce the application costs and to increment their performance. In order to reach the last aspect, it is important to note that the output characteristic of a pho...

Introduction: The Genesis Mission carried four collector arrays which where exposed to the solar wind depending upon solar conditions, representing the major solar regimes: Interstream is the “normal” SW, <500km/s, collected for 334 days by the L-array; Coronal Hole wind with speeds about 500-800 km/s was collected by the H-array for 313 days; the highest average and variable speed, Coronal Mas...

Induction Heating system utilizes electricity for the generation of heat, whereas solar energy is largely available energy source for generation of heat. Combining solar energy with induction heat generation technique is the efficient solution for the heat generation application. The proposed system presents an effective control scheme incorporated in half bridge series resonance induction heat...

This paper deals with the study of different type of MPPT (Maximum Power Point Tracking) algorithms in a solar photovoltaic system (SPV) in order to extract maximum power from the solar modules. Here the solar array is integrated with the grid to provide power, as the traditional sources of power generation is depleting at a faster rate and also to provide power during peak hours in urban areas...
