Solar Signals in Observation Indeed Implied Enhanced Predictability Since 1977

Option Returns and the Cross-Sectional Predictability of Implied Volatility∗

I study the cross-section of realized stock option returns and find an economically important source of predictability in the cross-sectional distribution of implied volatility. A zero-cost trading strategy that is long in straddles with a large positive forecast of the change in implied volatility and short in straddles with a large negative forecast produces an economically important and stat...

Solar Irradiance since 1874 Revisited

We reconstruct the solar irradiance since 1874 employing an evolved version of previously published models and improved sunspot and facular data. A good correlation between reconstructed irradiance and Earth’s global air temperature on time scales longer than the solar cycle is obtained and, in contrast to many earlier models, solar irradiance does not on average lag behind global temperature p...

Implied-voc and Suns-voc Measurements in Multicrystalline Solar Cells

Identifying loss mechanisms and predicting device performance are key goals of device and process characterization. Photoconductance measurements allow the extraction of the Implied Voc and Suns Voc, which together can be used for process monitoring, for loss analysis and to identify the potential device performance in the absence of unwanted defects. In this paper, we measure the Implied Voc a...
