Mfundo yosinthira mphamvu ya dzuwa kukhala mphamvu zosiyanasiyana ndi: mphamvu yowunikira imakondweretsa ma electron kuti apange mphamvu zamagetsi;kuyenda kwa ma electron kumapanga mphamvu yamagetsi, motero kutembenuza mphamvu ya kuwala kukhala mphamvu yamagetsi.
Njira yosinthira mphamvu ya dzuwa kukhala mphamvu yamagetsi imatchedwa photovoltaic power generation.Mfundo yopangira mphamvu ya photovoltaic ndiyo kugwiritsa ntchito ma photon mu kuwala kwa dzuwa kusangalatsa ma elekitironi mu cell photovoltaic kupanga panopa.Selo la photovoltaic ndi chipangizo cha semiconductor chomwe nthawi zambiri chimakhala ndi ma silicon wafers angapo.
Chophika cha silicon chili ndi zida ziwiri, silicon yopangidwa ndi phosphorous ndi silicon yopangidwa ndi boron, zomwe zimakhala ndi zida zamagetsi zosiyanasiyana.Kuwala kwa dzuŵa kukafika pa chowotcha cha silicon, ma photon amagunda ma elekitironi mu wafer wa silicon, kuwasangalatsa kuchokera ku maatomu awo ndi kupanga ma electron-hole pairs mu wafer.Silicon yopangidwa ndi phosphorous ndi semiconductor yamtundu wa n, ndipo silikoni yokhala ndi boron ndi semiconductor yamtundu wa p.Ziwirizo zikalumikizidwa, gawo lamagetsi limapangidwa, ndipo gawo lamagetsi limapangitsa kuti ma electron asunthike ndikupanga magetsi.
