A method, system, and software for calculating a multi factor temperature index includes determining the values of at least two weather related parameters. The multi factor temperature index is calculated using the calculated values of the two weather related parameters and an actual temperature value. The two weather related parameters are selected from a group consisting of a wind speed parameter, a solar intensity parameter, a dew point parameter, an atmospheric pressure parameter and a precipitation parameter.

The invention provides a method for predicting radiation of a photovoltaic power station based on an all-sky nephogram. The method comprises the steps of building a clear sky radiation model according to historical radiation data of clear sky of the photovoltaic power station; acquiring motion vectors and cloud form variation trends of cloud clusters with different thicknesses in a future time period by using the all-sky nephogram; acquiring the solar intensity in the cloud clusters; and building an ultra-short term radiation prediction model, and performing prediction on the radiation of the photovoltaic power station in the future time period. The method provided by the invention is accurate and effective, and can accurately predict the radiation of a future time period on the basis of ensuring predicted data output of basic weather types; accurate prediction for moving conditions of cloud clusters within a certain period of time in the future and conditions of radiation attenuation caused by shielding of various cloud clusters for the solar radiation is realized, so that the radiation of the photovoltaic power station in the future time period can be predicted accurately, accurate and effectively decision-making support is provided for power dispatching, thus the operation cost of an electric power system is reduced, and greater economic benefits and social benefits are acquired.

There is disclosed ultrahigh-efficiency single- and multi-junction thin-film solar cells. This disclosure is also directed to a substrate-damage-free epitaxial lift-off (''ELO'') process that employs adhesive-free, reliable and lightweight cold-weld bonding to a substrate, such as bonding to plastic or metal foils shaped into compound parabolic metal foil concentrators. By combining low-cost solar cell production and ultrahigh- efficiency of solar intensity-concentrated thin-film solar cells on foil substrates shaped into an integrated collector, as described herein, both lower cost of the module as well as significant cost reductions in the infrastructure is achieved.
