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

Investigations of CuInSe2 Thin Films and Contacts: Annual Subcontract Report, 1 January 1990 - 28 February 1991

Description: This report describes research into electrical contacts for copper indium diselenide (CulnSe2) polycrystalline thin films used for solar cell applications. Molybdenum contacts have historically been the most promising for heterojunction solar cells. This program studied contact stability by investigating thermally induced bilayer reactions between molybdenum and copper, indium, and selenium. Because selenization is widely used to fabricate CulnSe2 thin films for photovoltaic cells, a second par… more

PVWatts Version 1 Technical Reference

Description: The NREL PVWatts(TM) calculator is a web application developed by the National Renewable Energy Laboratory (NREL) that estimates the electricity production of a grid-connected photovoltaic system based on a few simple inputs. PVWatts combines a number of sub-models to predict overall system performance, and makes several hidden assumptions about performance parameters. This technical reference details the individual sub-models, documents assumptions and hidden parameters, and explains the seque… more

New Concepts for High-Intensity PV Modules for Use with Dish Concentrator Systems

Description: In this paper we report on our efforts to fabricate monolithically interconnected modules (MIMS) from GaAs device structures. The small size of the component cells comprising the MIM allows for operation at very high flux densities. This relaxes the requirement for a small spot-size to be generated by the optics. The devices are grown on semi-insulating substrates, allowing the incorporation of an extremely efficient back surface reflector (BSR). This BSR is an effective tool for thermal manage… more

New Microscopic Model of the Staebler-Wronski Effect in Hydrogenated Amorphous Silicon

Description: A new microscopic and kinetic model of light-induced metastability in hydrogenated amorphous silicon (a-Si:H) was recently proposed. Carrier recombination excites H from deep Si-H bonds into a mobile configuration, leaving a threefold-coordinated Si dangling bond (DB) defect at the site of excitation - a process long suspected to be an element of metastable DB production. Normally, mobile H are recaptured at DB defects and neither metastability nor net DB production results. However, when two m… more
