Methods

The four main methods used for the direct conversion of solar energy into electricity are related to photovoltaic power conversion, photoemissive power conversion, photogalvanic power conversion, and photomagnetic power conversion. Indirect conversion methods involving a heat stage are also considered, taking into account the conversion of solar energy into heat, the conversion of solar heat directly into electricity, and the indirect conversion of solar heat into electricity. A description is presented of approaches involving the conversion of solar energy through a mechanical stage. The conversion of solar energy through a chemical stage is potentially also feasible. Attention is given to primary photochemical processes for the conversion of solar energy and basic concepts regarding a solar energy power system
