A comparison is presented between semi-transparent mono-facial and bifacially active solar cells, including efficiency rates and production processes. The mono-facial efficiency rate was 10.4%, compared to 12.9% for bifacial, while mono-facial cells required a less elaborate production process than bifacial cells.

Research indicates that back-contacted silicon solar cells demonstrates several advantages over other solar cells. These include the emitter-wrap-through design, which creates a cell structure suitable for inexpensive base material, avoids grid shadowing losses and lowers module assembly costs.

The possible errors when characterizing silicon solar cells by means of the effective minority carrier diffusion length L(sub eff) are evaluated. Findings revealed that the approximations leading to the L(sub eff) result in considerable errors in the bulk diffusion length for certain parameter combinations even if the back surface recombination velocity is known. It is noted that these errors do not include an experimental uncertainties and are only due to an imprecise theoretical approach.
