Thin-film crystalline photovoltaic (PV) cell is a trend for future PV with its potential to achieve low cost and high efficiency. Concerning material utilization efficiency, we propose a method with a fast manufacturing method of thin crystalline Si by chemical solution. To obtain the highest efficiency of material utilization, experiments with different H2O2/HF ratio are conducted, where related...
Simulation data of the performance of amorphous hydrogenated silicon (a-Si:H) thin film solar cells using the software package Sentaurus TCAD (Synopsis Inc) are presented. The Sentaurus software is configured with standard theoretical models describing e. g. the density of states in the mobility gap of a-Si:H, generation/recombination statistics, optical data of a-Si:H thin films, etc. to calculate...
In this paper the photocurrent properties of the CdS/CdTe thin film solar cell were modeled by using relative physical models that were the incoherence model of the optical generation, the continuity equation for carriers and the current density equation. Then the effect of CdS and CdTe thickness on the photo current was simulated. The results of the simulation show that: a optimum CdTe thickness...
Silicon-based thin-film photovoltaics is on the way the overcome drawbacks such as high degradation and low efficiencies by applying novel multiple-junction solar cells consisting of amorphous and microcrystalline absorber layers. In order to produce reliable high-power low-cost solar modules the design of the back contact and back reflector is an important issue. In this paper, ersol Thin Film GmbH...
Surface texturing in bulk silicon solar cells leads to record high efficiencies due to the reduced reflection and increased optical path lengths. High efficiency thin film solar cells are also feasible with a combination of ultra-thin absorption layer and textured structural design. Based on the rigorous coupled-wave analysis, we report here the structural impact and optical optimization of thin film...
An initial efficiency of 14.7% (Jsc=14.4 mA/cm/sup 2/, Voc=1.41 V, FF=72.8%) has been achieved for a-Si:H/transparent inter-layer/microcrystalline Si solar cell (total area of 1 cm/sup 2/). The short circuit current (Jsc) was enhanced by the introduction of transparent interlayer, namely internal light trapping. The highest Jsc of 15 mA/cm/sup 2/ was obtained by this internal light trapping. It was...
