Technological Status and Market Trends of Photovoltaic Cell Industry

摘要

In this study, technological developments and market tendencies in photovoltaic cell (PV) industry are investigated. The increasing energy demand and decrease in conventional energy resources orientates researches to be in tendency to continuously increase the output of alternative energy resources. Today, crystal silicon cells significantly dominate tendencies in PV Cell market with their converting outputs exceeding 20% in small areas. However, a PV panel with silicon crystal is very expensive. To increase output efficiency by decreasing costs of PV cells and modules, nanotechnology approaches are very important. Nanomaterials that used in PV cell production, absorb sunlight better, increase the energy transformation and cheaper than other materials but require special fabrication fixtures. PV cell market is dominated by Japan and Germany. Installation tendencies are become dense on grid-connected systems. Although the costs of PV module per watt generally follow a horizontal route, system installation costs decrease regularly.
