The simplest semiconductor junction that is used in solar cells for separating photogenerated charge carriers is the p-n junction, an interface between the p-type region and ntype region of one semiconductor. Therefore, the basic semiconductor property of a material, the possibility to vary its conductivity by doping, has to be demonstrated first before the material can be considered as a suita...

We report the results of production start-up efforts at the 2MW Sovlux photovoltaic production line. Triple-junction solar cells with higher than 10% initial effXency were produced in this production line with subcell yield up to 96%. The production process demonstrated high reproducibility and consistency from run to run. 2 t? and 4 @ modules assembled in sovlux plant using these solar cell ma...

Optimizing any tandem solar cells design before making them experimentally is an important way of reducing development costs. Hence, in this work, we have used a complete analytical model that includes the effects depletion regions III-V compound order to simulate behavior two and four-terminal InGaP/GaAs//Si for optimizing them. The optimization procedure described first, then it shown expecte...

The ongoing energy transition to curb carbon dioxide emissions and meet the increasing demands have enhanced need for integration of renewable into existing electricity system. Solar has been gaining an market share over past decade. Multi-junction solar cells (MJSCs) enable efficient conversion sunlight without being bound by 33% limit as in commercialized single junction silicon cells. III-V ...

The defect-free IDDQ has two major components: (i) the reverse biased p-n junction leakage current, and (ii) the transistor sub-threshold leakage (off) current. The reverse biased p-n junction leakage current can be further divided into two segments: state dependent, and state independent. The state dependent component p-n junction leakage current depends on the reverse biasing of the p-n junct...
