Solanki C.S., Singh H.K. Anti-reflection and Light Trapping in c-Si Solar Cells

Springer, 2017. — 209 p. — ISBN: 978-981-10-4771-8.Solar photovoltaic technologies have been growing with over 35% CAGR annually, with annual production now crossing 77,000 MW. This is extremely impressive high production volume by any measure. About 90% of this production is done using crystalline Si wafers. Despite the competition from the other materials and technologies, strong growth in the crystalline Si cell technology and improvement in ef fi ciency has led to strong position of this technology in current market.
There is further scope for improvement in technology which will lead to cost reduction. International technology roadmap on crystalline Si cell technology has identi fi ed several areas of improvements in crystalline Si cell like front metal contact, front and back surface passivation, bulk material, reduction in wafer thickness, and alternative anti-re fl ection techniques. It is anticipated that the future crystalline Si solar cells will be much thinner than the current standard of 180 microns. In this scenario ef fi cient light harvesting becomes key to growth of the technology and cost reduction. Anti-re fl ection and light trapping techniques will play a key role in ef fi cient light trapping by future solar cells. In this context, this book brings an insight into various aspects related to re fl ection, refraction, and light trappings in c-Si cell technologies. Basic physics and technology for light trapping in c-Si-based solar cell has been covered starting from traditional light trapping structure to advanced light trapping structures based on nanostructures.
The book offers a valuable guide for graduate students, researchers and professionals interested in the latest trends in solar cell technologies.
