Photovoltaic thermal hybrid solar collector Photovoltaic thermal hybrid solar collector Photovoltaic thermal hybrid solar collectors, also known as hybrid PV/T (PVT) or solar cogeneration systems, are power generation technologies that convert solar radiation into usable thermal and electrical energy. Such systems combine a solar cell, which converts sunlight into electricity, with a solar thermal collector, which captures the remaining energy and removes waste heat from the PV module. These technologies can be more energy efficient overall than solar photovoltaic (PV) or solar thermal alone. Significant research has gone into developing a diverse range of PV/T technologies since the 1970s.. While many collector types have been
Serial module turns out that a serial ring "R" is a finite direct sum of homogeneously serial right ideals if and only if "R" is isomorphic to a full "n"x"n" matrix ring over a local serial ring. Such rings are also known as primary decomposable serial rings . Serial module In abstract algebra, a uniserial module "M" is a module over a ring "R", whose submodules are totally ordered by inclusion. This means simply that for any two submodules "N" and "N" of "M", either formula_1 or formula_2. A module is called a serial module if it is a direct sum of
