Crystalline-Silicon Solar Cells for the 21st Century


ABSTRACT
The worldwide market share for crystalline-silicon solar cells has
increased steadily in the last 10 years. In 1998, about 87% of the
photovoltaic modules shipped worldwide are based on crystalline
silicon. This dominance will likely continue into at least the first few
years of the 21st century. The long-term growth of crystalline-silicon
solar cells will depend on the development of low-cost ....etc

Solar power (photovoltaic) systems



INTRODUCTION

1.1 BACKGROUND OF THE PROJECT
The consumption of the energy is directly proportional to the progress of the mankind. With ever growing population, improvement in the living standard of the humanity, industrialization of the developing countries, the demand for energy increases day by day.
The primary source of energy is fossil fuel, though results environmental degradation caused by their widespr ....etc

Abstract
This paper presents the development of asimple 1.5kW single-phase sinusoidal Pulse WidthModulation (PWM) inverter. This inverter isdesigned to be either a stand-alone or grid connectedinverter from a direct supply of photovoltaic (PV)cells. The developed inverter unit converts the DCinput supply from the PV cells into a clean sinusoidalvoltage output. This power inverter is also capable tobe a grid

SOLAR CELLS


General Information

Research conducted by Panasonic over many years on solar cells and the application of this new technology culminated in 1984 with the successful development of the world’s first thin-film solar cell using compound semiconductors. The company named these cells Sunceram II. The Sunceram II cells have good weatherproof properties and high spectral sensitivity characteristics over a wide wavelength range. Furthermore, since the entire film-forming process involves only s ....etc
