Perovskite Photovoltaics: Basic to Advanced Concepts and Implementation, Second Edition brings together the latest advances in perovskite photovoltaics, associated challenges and opportunities, and how to achieve further developments. This edition presents new topics and novel areas, including defect engineering, interface engineering, additive engineering, anti-solvents, single crystal perovskite solar cells, inorganic perovskites, optoelectronic characterization, and mathematical modeling of perovskite solar cells. In addition, the book contains a detailed analysis of the implementation and economic viability of perovskite solar cells, highlighting what photovoltaic devices need to be generated by low cost, non-toxic, earth abundant materials using environmentally-scalable processes.This book is a valuable resource for all those with an interest in perovskite solar cells, photovoltaics, and more broadly solar energy and renewable energy, including researchers, scientists, graduate students, engineers, R&D professionals, and other industry personnel.

Provides detailed coverage of perovskite solar cells for targeted photovoltaics fields and applicationsIncludes commercialization examples of large-scale perovskite solar technology, giving users detailed analysis on implementation, technical challenges, economic viability, and lifecycleOffers a thoroughly updated new edition, covering a range of new and novel topics in perovskite solar cell technology

How social networks shaped the imperial Chinese stateChina was the world’s leading superpower for almost two millennia, falling behind only in the last two centuries and now rising to dominance again. What factors led to imperial China’s decline? The Rise and Fall of Imperial China offers a systematic look at the Chinese state from the seventh century through to the twentieth. Focusing on how short-lived emperors often ruled a strong state while long-lasting emperors governed a weak one, Yuhua Wang shows why lessons from China’s history can help us better understand state building.Wang argues that Chinese rulers faced a fundamental trade-off that he calls the sovereign’s dilemma: a coherent elite that could collectively strengthen the state could also overthrow the ruler. This dilemma emerged because strengthening state capacity and keeping rulers in power for longer required different social networks in which central elites were embedded. Wang examines how these social networks shaped the Chinese state, and vice versa, and he looks at how the ruler’s pursuit of power by fragmenting the elites became the final culprit for China’s fall.Drawing on more than a thousand years of Chinese history, The Rise and Fall of Imperial China highlights the role of elite social relations in influencing the trajectories of state development.

Under what conditions would authoritarian rulers be interested in the rule of law? What type of rule of law exists in authoritarian regimes? How do authoritarian rulers promote the rule of law without threatening their grip on power? Tying the Autocrat's Hands answers these questions by examining legal reforms in China. Yuhua Wang develops a demand-side theory arguing that authoritarian rulers will respect the rule of law when they need the cooperation of organized interest groups that control valuable and mobile assets but are not politically connected. He also defines the rule of law that exists in authoritarian regimes as a partial form of the rule of law, in which judicial fairness is respected in the commercial realm but not in the political realm. Tying the Autocrat's Hands demonstrates that the rule of law is better enforced in regions with a large number of foreign investors but less so in regions heavily invested in by Chinese investors.
