Module Technology: Current Practice and Issues

Description: PV modules must provide mechanical support for the cells, protect the world from the voltages inside, protect the cells, diodes and interconnects from the weather outside, couple as much light as possible into the PV cells and minimize the temperature increase of the cells. The package must continue to serve these functions for at least 25 years as that is the typical module warranty period today. Furthermore the package must do all this for as low a cost as possible since the key to large scal… more

Test-to-Failure of Crystalline Silicon Modules: Preprint

Description: Accelerated lifetime testing of five crystalline silicon module designs was carried out according to the Terrestrial Photovoltaic Module Accelerated Test-to-Failure Protocol. This protocol compares the reliability of various module constructions on a quantitative basis. The modules under test are subdivided into three accelerated lifetime testing paths: 85..deg..C/85% relative humidity with system bias, thermal cycling between ?40..deg..C and 85..deg..C, and a path that alternates between damp … more

Research on stable, high-efficiency, amorphous silicon multijunction modules. Final subcontract report, 1 May 1990--30 June 1993

Description: This report describes work performed dudng the period 1 July 1992 through 30 June 1993. Dudng this period, major improvements were achieved in the stabilized conversion efficiency of triple-junction modules. These resulted in the demonstration of triple-junction initial conversion efficiency of 11.3% and stabilized conversion efficiency of approximately 9%. Significant advances were made in the deposition of a-Si:H intrinsic layers that led to higher open-circuit voltage and improved stability.… more

Development of a Visual Inspection Checklist for Evaluation of Fielded PV Module Condition (Presentation)

Description: A visual inspection checklist for the evaluation of fielded photovoltaic (PV) modules has been developed to facilitate collection of data describing the field performance of PV modules. The proposed inspection checklist consists of 14 sections, each documenting the appearance or properties of a part of the module. This tool has been evaluated through the inspection of over 60 PV modules produced by more than 20 manufacturers and fielded at two different sites for varying periods of time. Aggreg… more

Real-Time and Accelerated Solar Weathering of Commercial PV Modules: Preprint

Description: Presented at the 2001 NCPV Program Review Meeting: We report the observed degradation in 6 different types of PV modules as a function of total UV exposure and give a number of recommendations for future weathering tests. Since 1997, using existing ASTM standards for weathering of materials, we have been conducting a solar weathering program on a group of six different types of photovoltaic (PV) modules. The methods used include real-time outdoor, accelerated outdoor, and accelerated indoor wea… more
