Third Generation Photovoltaics
Photovoltaics, the direct conversion of sunlight to electricity, is now the fastest growing technology for electricity generation. Present "first generation" products use the same silicon wafers as in microelectronics. "Second generation" thin-films, now entering the market, have the potential to greatly improve the economics by eliminating material costs. Martin Green, one of the world’s foremost photovoltaic researchers, argues in this book that "second generation" photovoltaics will eventually reach its own material cost constraints, engendering a "third generation" of high performance thin-films. The book explores, self-consistently, the energy conversion potential of advanced approaches for improving photovoltaic performance and outlines possible implementation paths.

Gravity Vs. the Girl
Samantha Green has just spent an entire year in her pajamas, and she is beginning to regret it. What's more, she is haunted by four ghosts that are former versions of herself. First up is the overachieving and materialistic attorney, who is furious with Samantha for throwing away the career she worked so hard to build. Second is the lackadaisical college student who is high on life but low on responsibility. Next is the melodramatic teenager, who is consumed with her social standing, teal eyeliner and teased bangs. Finally, there is the scrappy six-year old, whose only objective is to overcome gravity so that she can fly. Samantha's ghosts alternate between fighting with each other, rallying around Samantha's budding sanity and falling in love with a string of good-for-nothing drummers. Despite her reluctance to do so, Samantha must rely on these spirits from the past to repair the present and ensure her future.
From Space to Earth
From Space to Earth tracks the evolution of the technology of photovoltaics, the use of solar cells to convert the sun's energy into electricity. John Perlin's painstaking research results in a fascinating account of the development of this technology, from its shaky nineteenth-century beginnings mired in scientific controversy to its high-visibility success in the space program, to its current position as a versatile and promising power source.

Do Right and Fear No One
'If deaths are not investigated, then the authorities cannot be held to account and democracy is threatened. And if deaths are not investigated, we are not a society that values human life.' Inspired from a young age to help the marginalised and voiceless, Leslie Thomas QC has dedicated his career to fighting for the underdog and holding the State to account. This intimate and personal record of some of the most significant, controversial and disturbing legal cases of the last fifty years lays bare the very heart of the law enforcement and judicial process. It's an unforgettable account of an idealistic and outspoken lawyer's coming of age as a Black man in London, and a powerful portrait of the lives of those he has fought for. From the Grenfell Tower Inquiry, to the deaths of Christi and Bobby Shepherd by carbon monoxide poisoning, the Birmingham Pub Bombings and the police shooting of Mark Duggan, Do Right and Fear No One present a blistering argument for a level playing field in the pursuit of justice.
Peterson Reference Guide to Sparrows of North America
Sparrows are as complicated as they are common. This is an essential guide to identifying 76 kinds, along with a fascinating history of human interactions with them. What, exactly, is a sparrow? All birders (and many non-birders) have essentially the same mental image of a pelican, a duck, or a flamingo, and a guide dedicated to waxwings or kingfishers would need nothing more than a sketch and a single sentence to satisfactorily identify its subject. Sparrows are harder to pin down. This book covers one family (Passerellidae), which includes towhees and juncos, and 76 members of the sparrow clan. Birds have a human history, too, beginning with their significance to native cultures and continuing through their discovery by science, their taxonomic fortunes and misfortunes, and their prospects for survival in a world with ever less space for wild creatures. This book includes not just facts and measurements, but stories--of how birds got their names and how they were discovered--of their entanglement with human history.
