Abstract: Disclosed is a building blocks method for low-cost fabrication of single crystal organometallic perovskite materials with pseudo crystallized hole transporting material layer. This method uses self-assembled molecular monolayers SAM as building blocks. This approach enables creation of defect-free perovskite crystals with desired morphology and crystallinity in a controlled way. Additionally, the crosslinked molecular layers SAM play a role of hole transporting materials HTM and encapsulation against diffusion of metal atoms and gas molecules, thus enhancing the stability of the perovskite materials. This method is cost effective and can be scaled up.

Abstract: The present disclosure provides a new and innovative system, method, and non-transitory computer-readable medium for securely recovering access to an online service account. Secret splitting is utilized to require multiple recovery mechanisms in order to recover access to an online service account, thus decreasing the likelihood that a malicious attacker will compromise all of the recovery mechanisms to gain access to the online service account. The secret is split into a quantity of tokens via a secret sharing function that can reconstruct the secret with a predetermined threshold quantity of the tokens. The level of security provided by the system is flexible by adjusting the quantity of recovery mechanisms and the predetermined threshold quantity of tokens required to reconstruct the secret.

Abstract: The method of forecasting for solar-based power systems (10) recognizes that no single solar irradiance forecasting model provides the best forecasting prediction for every current weather trend at every time of the year. Instead, the method trains a classifier to select the best solar irradiance forecasting model for prevailing conditions through a machine learning approach. The resulting solar irradiance forecast predictions are then used to allocate the solar-based power systems (10) resources and modify demand when necessary in order to maintain a substantially constant voltage supply in the system (10).
