The conversion of solar light into electric power requires the generation of both negative and positive charges as well as a driving force that can push these charges through an external electric circuit. When connected to the external electric circuit any electrical device, such as
Solar cell efficiency tables (version 23)
free download
Consolidated tables showing an extensive listing of the highest independently confirmed efficiencies for solar cells and modules are presented. Guidelines for inclusion of results into these tables are outlined and new entries since July 2003 are reviewed. Copyright 2004 The development of a new efficient and stable semiconductor-liquid junction solar cell is reported. The n-CuInSe 2/I 2-I−-Cu+-HI/C cell utilizes relatively inexpensive, non-toxic components and requires less stringent sealing which makes this cell a more feasible It is my great pleasure to present our book P3HT Revisited from Molecular Scale to Solar (3-hexylthiophene), P3HT, which was first synthesized in the early 1990s and has become
