You can use Li ion battery with the tripple junction solar cells. In order to make the configuration universal you need to connect battery charge controller between the PV source and the battery. The PV module must be capable to supply the required nominal charging current at the normal illumination. It must also has a voltage greater than the maximum voltage of the battery. So, it must be able to output the total charging energy in the day time.

Your li ion batteries can be charged from either the dc or ac of hcpv system using charge controllers or bidirectional converters respectively. It depends on the configuration you that suits your purpose.
