    (ECS Transactions, 2022) Thejasiri, A.; Kafi, F. S. B.; Wijesundera, R.; Siripala, W.
    In this stud y, we have investigated the possibility of improving the Voe, FF and 1J values of Cu20 solar cells while preserving the resulted high Jsc values. Here we report that controlling the growth of p-Cu20 by varying the lactic acid ion concentration of thin film p-Cu20 deposition bath has improved the performance of Cu20 homo junction solar cell while preserving high J sc value. The fabricated surface treated thin film p-n homojunction solar cell has resulted Jsc = 12.95 mA cm-2, Voe = 445 mV, FF = 39.5% and 1J = 2.28%. The efficiency reported here is very significant in respect of Cu20 homojunction solar cells because it clearly demonstrates the possibility of adapting the low cost Cu20 material and fabrication methods in achieving a commercially viable solar cell.
