Strategies to increase CdTe solar-cell voltage

There is a significant difference in performance between today's highest efficiency of CdTe solar cells and single-crystal cells of comparable band gap. The largest contribution to this difference is the voltage, where the values for the best CdTe cells are about 230 mV below the best GaAs cells when an appropriate adjustment is made for band gap. CdTe voltage and fill-factor are currently compromised by low recombination lifetime (near 1 ns), low hole density (near 10¹⁴ cm^− 3), and in some cases an excessive back-contact barrier. Numerical simulation is used to evaluate how combinations of lifetime, carrier density, back electron reflection, and interfacial properties affect voltage and cell performance. Two different strategies for improving voltage and performance are explored.

A fuzzy multicriteria evaluation system for the assessment of tunnels vis-à-vis surface roads: the WPMA case—part II

The Fuzzy Multicriteria Evaluation System (FUMES) is applied on a real evaluation problem such as the Western Peripheral Motorway of Athens (WPMA). The lack of a formal development model of the study area suggested an evaluation strategy, which is characterized by the high uncertainty of the evaluation environment. This has resulted in using judgments when quantitative information on the performance of the tunnel or the surface road was not available. It also resulted in employing a relatively large number of alternative scenarios to deal with the different policy goals. The attempted impact analysis generated crisp and fuzzy scores for each competing alternative. The different scenarios under which the various alternatives were evaluated are of two types: socio-economic and policy scenarios. Subsequently, the criteria weights were computed using the Fuzzy Hierarchical Analysis and the different CBA and MCA methods were applied. Finally, the output of the evaluation determined that the surface road is the most ‘stable’ solution for all the ‘extrovert’ development scenarios, while the tunnel is more preferable for all the ‘introvert’ development scenarios.
