Abstract

We present a simple method for passivation of silicon solar cells at room temperature. Oleylamine has been used as passivation agent on the n-type emitter of silicon solar cell surface. The desired effect is seen in the form of apparent enhancement in efficiency of the solar cell after coating. The efficiency increases by an amount of 14 % as compared to the one without any passivation applied and antireflection coating. The efficiency was found to decrease marginally and stabilized later. Device performance was monitored for 100 h and the efficiency was found higher as compare to bare solar cell without passivation coating.
