Question: What is the total number of t (µm), when Technology is u c-si?
SQL: SELECT COUNT("t_m") FROM "comparison_with_other_technologies" WHERE "technology"='u c-si';

Question: What is the V OC (V), when t (µm) is greater than 5, and when I SC (A) is 0.8?
SQL: SELECT "v_oc_v" FROM "comparison_with_other_technologies" WHERE "t_m">5 AND "i_sc_a"='0.8';
